24 –RESET*IDevice Reset (with pull-up). The active low –RESET input resets the device logic
and returns the configuration of the device to the original factory default values or
"stored values" in the NVRAM. –RESET is tied to VCC through a time-constant
circuit for “Power-on-Reset” functionality. The SocketModem is ready to accept
commands after a fixed amount of time (“X” Time) after power-on or reset.

*The SocketModem device may respond to a shorter reset pulse.
Reset Line Interface for the MT5692SMI. The modem’s reset line employs a 10K
pull up resistor. If an open collector driver is to be used, run that output to the
modem only and use a separate driver for other embedded components. The
modem’s reset signal may also be driven by a circuit that both sinks and sources
current if desired. It is also important to note that these modems do not require an
external reset. They have their own internal reset circuitry and voltage monitor and
will function correctly even if the reset input is open.
Reset GPRS and CDMA (MTSMC-G2 and MTSMC-C1). This signal is used to
force a reset procedure by providing low level during reset of at least 500us.The
signal is considered an emergency reset only. A reset procedure is already driven
by internal hardware during the power-up sequence. If no external reset is
necessary, this input can be left open. If used (emergency reset), it has to be driven
by an open collector or an open drain.
Reset EDGE with pull-up (MTSMC-E1). The active low –RESET input resets the
device logic and returns the configuration of the device to the original factory default
values of "stored values" in the NVRAM. The SocketModem is ready to accept
commands after a fixed amount of time after power-on or reset.
Reset for MT810SWM-IP. It can take up to 45 seconds before the MT810SWM-IP
is ready to accept AT Commands. When configuring the MT810SWM-IP using
security mode WPA or WPA2, the bootup will take longer.

33 –RTS I Request to Send (Active Low). –RTS is controlled by the DTE to indicate whether
or not the DTE is ready to receive data. –RTS ON (low) indicates that the DTE is
ready to receive data from the modem on RXD. –RTS OFF indicates to the
SocketModem that it should not transfer data on the RXD.
Note: When the –RTS pin is not in use, it should be tied low.
* RESET – A Design Consideration: Allowing the host processor to control the RESET line of the SocketModem provides
the benefit of allowing the host to reset the device in the event of a failure to respond normally. Resetting the SocketModem
will return it to a known functional state.

Pin Signal
Name
In/Out Description
34 –RXD O Received Data. The SocketModem uses the RXD line to send data to the DTE and to
send SocketModem responses to the DTE. In command mode, –RXD data presents
the SocketModem responses to the DTE. SocketModem responses take priority over
incoming data when the two signals are in competition for –RXD. When no data is
transmitted, the signal is held in mark condition.
35 –TXD I Transmitted Data. The DTE uses the –TXD line to send data to the SocketModem for
transmission or to transmit commands to the SocketModem. The DTE holds this circuit
in mark state when no data is being transmitted or during intervals between characters.
36 –RI O RING (Active Low). Incoming ring signal from phone.
Ring Indicate. –RI output ON (low) indicates the presence of an ON segment of a ring
signal on the telephone line. The modem will not go off-hook when –RI is active; the
modem waits for –RI to go inactive before going off-hook.
SocketWireless Bluetooth (MTS2BTSMI). Strobes 1/sec for slave indication.
37 –DSR O Data Set Ready (Active Low). –DSR indicates SocketModem status to the DTE. –
DSR OFF (high) indicates that the DTE is to disregard all signals appearing on the
interchange circuits except Ring Indicator (–RI). It reflects the status of the local data
set and does not indicate an actual link with any remote data equipment.
38 –CTS O Clear to Send (Active Low). –CTS is controlled by the SocketModem to indicate
whether or not the SocketModem is ready to transmit data. –CTS ON indicates to the
DTE that signals on TXD will be transmitted. –CTS OFF indicates to the DTE that it
should not transfer data on TXD.
39 –DCD O Data Carrier Detect (Active Low). –DCD output is ON (low) when a data connection
is established and the SocketModem is ready to send/receive data.
40 –DTR I Data Terminal Ready (Active Low). The –DTR input is turned ON (low) when the DTE
is ready to communicate. –DTR ON prepares the modem to be connected, and, once
connected, maintains the connection. –DTR OFF places the modem in the disconnect
state under control of the &Dn and &Qn commands.
Note: When the –DTR pin is not in use, it should be tied low.

Design Considerations
Noise Suppression Design Considerations
Engineering noise-suppression practices must be adhered to when designing a printed circuit board (PCB)
containing the SocketModem.Suppression of noise is essential to the proper operation and performance of the
modem itself and for surrounding equipment.
Two aspects of noise in an OEM board design containing the SocketModem must be considered: on-board/off-
board generated noise that can affect digital signal processing. Both on-board and off-board generated noise
that is coupled on-board can affect interface signal levels and quality. Of particular concern is noise in frequency
ranges affecting modem performance.
On-board generated electromagnetic interference (EMI) noise that can be radiated or conducted off-board is a
separate, but equally important, concern. This type of noise can affect the operation of surrounding equipment.
Most local government agencies have stringent certification requirements that must be met for use in specific
environments.
Proper PC board layout (component placement, signal routing, trace thickness and geometry, etc.) component
selection (composition, value, and tolerance), interface connections, and shielding are required for the board
design to achieve desired modem performance and to attain EMI certification.
Other aspects of proper noise-suppression engineering practices are beyond the scope of this designer guide.
The designer should consult noise suppression techniques described in technical publications and journals,
electronics and electrical engineering text books, and component supplier application notes.
PC Board Layout Guidelines
In a 4-layer design, provide adequate ground plane covering the entire board. In 4-layer designs, power and
ground are typically on the inner layers. All power and ground traces should be 0.05 inches wide.
The recommended hole size for the SocketModem pins is 0.036 in. +/-0.003 in. in diameter. Spacers can be
used to hold the SocketModem vertically in place during the wave solder process.
All creepages and clearances for the SocketModem have been designed to meet requirements of safety
standards EN60950 or EN60601. The requirements are based on a working voltage of 125V or 250V. When the
recommended DAA* circuit interface is implemented in a third party design, all creepage and clearance
requirements must be strictly followed in order to meet safety standards. The third party safety design must be
evaluated by the appropriate national agency per the required specification.
User accessible areas: Based on where the third party design is to be marketed, sold, or used, it may be
necessary to provide an insulating cover over all TNV exposed areas. Consult with the recognized safety
agency to determine the requirements.
Note: Even if the recommended design considerations are followed, there are no guarantees that a particular
system will comply with all the necessary regulatory requirements. It is imperative that specific designs be
completely evaluated by a qualified/recognized agency.
*DAA stands for Data Access Arrangement. DAA is the telephone line interface of the SocketModem.
Important – Tooling Holes for Mounting
Hardware on the Board
It is recommended that nylon hardware be used if the SocketModems are to be mounted on the board using the
two tooling holes on the board due to possible traces and vias around the tooling holes.
For Cellular SocketModems:
#4 or M2/M3 hardware should be used for mounting the following cellular SocketModems to the board:
SocketModem® Cell & SocketModem® iCell GPRS (MTSMC-G2)
SocketModem® Cell and SocketModem® iCell CDMA 1xRTT (MTSMC-C1)
SocketModem® Cell & SocketModem® iCell HSPA (MTSMC-H4/H3)
SocketModem® Cell & SocketModem® iCell EV-DO (MTSMC-EV2/EV1)
For the MT5692SMI Analog SocketModem:
#2 or M2 for hardware should be used for mounting the analog modem on the board when the tooling hole
diameter on the board is .093.
#4 or M3 for hardware should be used for mounting the analog modem on the board when the tooling hole
diameter on the board is .128

E
Electromagnetic Interference (EMI)
Considerations
The following guidelines are offered specifically to help minimize EMI generation. Some of these guidelines are
the same as, or similar to, the general guidelines but are mentioned again to reinforce their importance. In order
to minimize the contribution of the SocketModem-based design to EMI, the designer must understand the major
sources of EMI and how to reduce them to acceptable levels.
1. Keep traces carrying high frequency signals as short as possible.
2. Provide a good ground plane or grid. In some cases, a multilayer board may be required with full layers
for ground and power distribution.
3. Decouple power from ground with decoupling capacitors as close to the SocketModem power pins as
possible.
4. Eliminate ground loops, which are unexpected current return paths to the power source and ground.
5. Decouple the telephone line cables at the telephone line jacks. Typically, use a combination of series
inductors, common mode chokes, and shunt capacitors. Methods to decouple telephone lines are
similar to decoupling power lines; however, telephone line decoupling may be more difficult and
deserves additional attention. A commonly used design aid is to place footprints for these components
and populate as necessary during performance/EMI testing and certification.
6. Decouple the power cord at the power cord interface with decoupling capacitors. Methods to decouple
power lines are similar to decoupling telephone lines.
7. Locate high frequency circuits in a separate area to minimize capacitive coupling to other circuits.
8. Locate cables and connectors so as to avoid coupling from high frequency circuits.
9. Lay out the highest frequency signal traces next to the ground grid.
10. If a multilayer board design is used, make no cuts in the ground or power planes and be sure the
ground plane covers all traces.
11. Minimize the number of through-hole connections on traces carrying high frequency signals.
12. Avoid right angle turns on high frequency traces. Forty-five degree corners are good; however, radius
turns are better.
13. On 2-layer boards with no ground grid, provide a shadow ground trace on the opposite side of the
board to traces carrying high frequency signals. This will be effective as a high frequency ground return
if it is three times the width of the signal traces.
14. Distribute high frequency signals continuously on a single trace rather than several traces radiating
from one point.
Electrostatic Discharge Control
All electronic devices should be handled with certain precautions to avoid damage due to the accumulation of
static charge.
See the ANSI/ESD Association Standard (ANSI/ESD S20.20-1999) – a document “for the Development of an
Electrostatic Discharge Control for Protection of Electrical and Electronic Parts, Assemblies and Equipment.”
This document covers ESD Control Program Administrative Requirements, ESD Training, ESD Control Program
Plan Technical Requirements (grounding/bonding systems, personnel grooming, protected areas, packaging,
marking, equipment, and handling), and Sensitivity Testing.
Multi-Tech Systems, Inc. strives to follow all of these recommendations. Input protection circuitry has been
incorporated into the Multi-Tech devices to minimize the effect of this static buildup, proper precautions should
be taken to avoid exposure to electrostatic discharge during handling.
Multi-Tech uses and recommends that others use anti-static boxes that create a faraday cage (packaging
designed to exclude electromagnetic fields). Multi-Tech recommends that you use our packaging when
returning a product and when you ship your products to your customers.
Phone Line Warning Statement for the Developer
Board
Use extreme caution when the phone line is installed due to live energized components. In fact, do not touch
any components on the board while the phone line is installed.
In addition, the phone line should be detached when making modifications to or servicing the developer board.

XMODEM Serial Port for Firmware Upgrade
Note: This upgrade procedure applies only to the MT810SWM-IP and the older product MTXCSEM.
The IP communications device, for example, contains a 2 MB flash wherein the boot image, the firmware and
configuration files are stored in a compressed format. The flash can easily be upgraded both locally as well as
remotely.
Serial Port Upgrade
The modem can be upgraded locally through the serial port using the upload feature of serial applications.
Serial Port Configuration
The default serial port parameters should be:
Data length – 8 bits
Parity – None
Stop bits – 1
Baud-rate of the serial port to which the communications device is connected should be set to 115200 bps
for proper operation.
Example of a Serial Flash Upgrade
Following steps explain the procedure to upgrade a flash using the serial COM port (serial flash upgrade).
Connect the communications device to a PC COM Port.
xOpen an application through which we can access the serial device (e.g., Meterm, zoc, hyperterm).
xReboot the communications device.
xWait for the boot message and prompt “press d to download” to appear.
xPress dwhen prompted.
xSelect the XMODEM Protocol from the Terminal application.
xChoose a file to be uploaded.
xPerform a file upload.
The communications device reboots and will be up after a few seconds (10-15 seconds).
Caution: Refrain from powering off the device during flash upgrade.

Other Supported Boot Code Commands
2.1 ATI0 - returns 000 or 247 for ISDN
2.2 ATI1 - returns boot code version number MM.mmn where
MM = unique code for each different platform that has boot code
mm = version number of boot code
n = version letter of the boot code
Examples: 2.05e, 2.12d, 35.15
ATI4- Boot code date and time.
Other Programming Concerns
1. The packets sent to the modem must be presorted by address and aligned on 128 byte boundaries (i.e., each
packet must start on an address that is a multiple of 128).
2. The packets should also be a minimum of 128 bytes with the non-programmed bytes set to the hex value of FF.
3. The packets sent to the modem must not span a 4K boundary (i.e., start the packet before it and go over the
boundary in the middle of the packet).
4. The 10-millisecond delay between M’s at the beginning of the handshake is so that the modem can sync up to
the start bit. If the M’s are sent one right after another, a data bit might be mistaken as a start bit.
5. Multi-Tech firmware files are in Intel Hex Format and must be read in and formatted into 128-4096 byte blocks
before being sent to the modem.
Information about the Intel Hex Format
An Intel Format Hex File is a text file consisting of “records”, one per line, that start with a “:” character and include
only digits 0-9 and letters A-F. There are three different record types: Extended Address Records, Data Records,
and End of File Records.
Data records contain the actual data that is to be programmed into a device. The address contained in the data
record needs to be combined with an extended address (by adding the extended address shifted four bits left to the
data record address) to determine the actual programming address for the data. If no extended address record is
before a given data record in the file, then the extended address value is assumed to be zero.
Data Record
Char Pos Field Type Value Description
1 Record Start “:”
2-3 Data Byte Count “NN” Maximum value is FF (which is 255 data bytes).
Typical is 20h which causes the hex record to fit in 80
columns.
4-7 Address “XXXX” Lower 16 bits of 20 bit address, most significant byte
first. This must be added to Extended Address left
shifted four bits.
8-9 Record Type “00” Data Record
10+N Data Bytes “YY..YY

Canadian Labeling Requirements (for Dial-Up Modems)
The following requirements are established under section 69.3 of the Telecommunications Act for purposes of
section 5 of the Telecommunications Apparatus Regulations.
Registered equipment shall bear the following identifying marks, and the Declaring Party shall ensure that these
marks are permanently affixed to the equipment:
(a) The registration number — Specifications of this mark are given in the document: Self-Marking of the
Certification/Registration Number on Terminal Equipment — Application Procedure and Agreement; and
(b) The model identification number under which the product was registered.
A statement of compliance with Industry Canada requirements, such as the one given below, shall accompany
each unit of equipment whether registered under this procedure or previously certified:
"This product meets the applicable Industry Canada technical specifications"
For terminal equipment intended for connection to loop-start or ground-start interfaces, the Ringer Equivalence
Number (REN) must be calculated as per Section 1.8 of CS-03, Part I. A REN higher than that determined may
be assigned by manufacturers to allow for production variations. The REN must be marked on the terminal
equipment itself or added to the note below. A note similar to the following shall accompany each unit of
equipment whether registered under this procedure or previously certified:
"The Ringer Equivalence Number is an indication of the maximum number of devices allowed to be
connected to a telephone interface. The termination on an interface may consist of any combination of
devices subject only to the requirement that the sum of the RENs of all the devices does not exceed
five".
Pursuant to section 69.3 of the Telecommunications Act, certified or self-declared TE will bear a valid identifying
certification number or registration number. The marking of the certification or registration number on the
product shall be as follows:
(a) TAC holder/DP will be responsible for permanently affixing the certification/registration number on the TE.
The certification/registration number (see example below) identifies Certified or self-declared TE to the
public, representatives of the telecommunications common carriers, the Department, and other interested
parties. The letter height must be no less than 1.5 mm and the letters must be legible without magnification.
(b) For integrated devices, e.g. a modem or one that is intended to become a sub-assembly of host equipment
e.g. a data terminal, computer etc. that are designed to interface directly with the network, the
certification/registration number shall be affixed to the integrated device itself.
(c) The certification/registration number for a packaged TE will denote that the total package has been
registered. However, the marking will normally be placed on that unit of the package which connects to the
network; e.g., in a PBX the marking will be placed on the common equipment which connects to the
network, rather than on plug-in components which may be added later. The Terminal Equipment List will
show the common equipment but not the standard station apparatus or any proprietary station apparatus.
(d) The marking format of the certification/registration number is as follows:
IC: XXXXXX-YYYYYYYY
Where:
xThe letters "IC" have no other meaning or purpose than to identify the Industry Canada
certification/registration number, and
x“XXXXXX-YYYYYYYY” is the certification/registration number; “XXXXXX” is the Company Number¹ (CN);
it consists of up to six alphanumeric characters (A-Z, 0-9) assigned by Industry Canada; and
“YYYYYYYY” is the Unique Product Number (UPN); it consists of up to eight alphanumeric characters (A-
Z, 0-9) assigned by the applicant. Other characters, (such as & # *-) may not be used. Alphabetic
characters must be capitalized.
¹ Note: The Company Number of registered equipment ends with an alphabetic character.
(e) Certification Numbers granted prior to the implementation of the above marking format are grandfathered.
(i) For previously certified TE, the self-marking format shall consist of the old certification number
preceded by “IC:” For example, if the certification number is “123 1234 A”, then the self-mark would
read “IC: 123 1234 A”.
(ii) For a new model that is registered to a family of previously certified TE, the self-marking format shall
be: IC: XXXXXX-ZZZZZZZZ
Where:
x“XXXXXX” is the Company Number, as in (d) above; and
x“ZZZZZZZZ” is either the old certification number minus the old company number, or a new Unique
Product Number assigned by the applicant. For example, if a new model is registered to the family of
products with certification number “123 1234 A”, and that the Company Number for the registration is
“123A”, then the self-mark for this new model would read “IC: 123A-1234 A”. If the applicant decides to
replace “1234 A” with a new UPN, say “5678", then the self-mark would read “IC: 123A-5678".

Note: The radio's performance may be affected at the temperature extremes. This is considered normal. The radio is
designed to automatically fallback in class and reduces transmitter power to avoid damage to the radio. There is no single
cause for this function. Rather, it is the result of an interaction of several factors, such as the ambient temperature, the
operating mode and the transmit power.

RF Connection and Antenna
The RF connector on the SocketModem GPRS is a UFL standard type. See Chapter 1 for Antenna System details.
Microphone Inputs
Note: For Voice Build Only.
The MIC inputs are differential ones. They already include the convenient biasing for an electret microphone (0.5 mA
and 2 Volts). This electret microphone can be directly connected on these inputs. The impedance of the microphone
has to be around 2K. These inputs are the standard ones for a handset design.
The gain of the MIC inputs is internally adjusted. The gain can be tuned from 30dB to 51dB. The connection to the
microphone is direct.

Changing the Quad Band
If for any reason, such as moving the modem from one geographical area to another, you want to change the band,
you can accomplish this by using the +WMBS AT Command.
Steps for Changing the GSM Band
Use a terminal application such as HyperTerminal for entering the AT Command.
1. To open HyperTerminal, click Start. Then select Programs >Accessories > Communications. Then
click HyperTerminal.
2. When the command window opens, type AT+WMBS=<Band><Param>. Press Enter.
xFor <Band>, enter the option you desire:
4= Dual-band mode 850/1900MHz
5=Dual-band mode 900/1800MHz
xFor <Param>, enter the option you desire:
0= Modem must be reset in order to use the specified band(s). This is the default.
1= Modem restarts immediately using the specified band(s).
Example: AT+WMBS=4,0. Press Enter.

Note: The radio's performance may be affected at the temperature extremes. This is considered normal. The radio is
designed to automatically fallback in class and reduces transmitter power to avoid damage to the radio. There is no single
cause for this function. Rather, it is the result of an interaction of several factors, such as the ambient temperature, the
operating mode and the transmit power.

Important – Tooling Holes for Mounting Hardware
on the Board
It is recommended that nylon hardware be used if the SocketModem is to be mounted on the board using the two
tooling holes on the board due to possible traces and vias around the tooling holes.
For Cellular SocketModems:
#4 or M2/M3 hardware should be used for mounting this cellular SocketModem to the board.

SocketModem Parallel Interface Internal Registers
The SocketModem parallel interface is a mimic of a 16C550A UART. It is similar to the MIMIC interface used in the Zilog
Z80189. The SocketModem mimic (MMM) takes advantage of this standard interface while replacing the serial to parallel data
transfer with a less complicated parallel to parallel data transfer.
The MMM interface controls an 8-bit parallel data transfer which is typically interrupt driven. Interrupts usually indicate one or
both of two conditions: (1) the receive (RX) FIFO has either reached a trigger level or time-out condition and needs to be
emptied and/or (2) the transmit (TX) FIFO is empty and waiting for more data from the Host. An interrupt can also be
triggered by a change in the modem status register (i.e., loss of carrier) or by the occurrence of errors in the line status
register (overrun, parity, framing, break detect).
In addition to the receive and transmit FIFOs, there are twelve other control/status registers called the MMM register set
which can be accessed through this interface.
Overview
SocketModem MIMIC (MMM) Operation
Data flow through MMM is bi-directional. Simultaneously, data can flow from the host through the transmit FIFO
to the SocketModem controller, and data can flow from SocketModem controller through the receive FIFO to the
Host. In the receive path, 8-bit data is asynchronously received (from the SocketModem controller) by the
receive FIFO where it is stored along with associated three error bits. The error bits must arrive (via a
SocketModem controller I/O write to MMM shadow line status register) prior to receiving the actual data bits.
The error bits are then temporarily stored so they may be written, with associated data bits, to the 11-bit wide
RX FIFO.
After every data write, the RX FIFO write pointer is incremented. RX FIFO trigger levels, data ready signal, and
time-out counter are checked to see if a Host-interrupt needs to be sent. The data ready signal will be activated
and MMM sits poised to accept another data word.
We highly recommend the host should read the MMM IIR register to determine the type of interrupt. Then it
might check bit 7 of the LSR to see if there are any errors in the data currently residing in the receive FIFO.
Finally, it will (1) alternately read a data word through the RX FIFO read pointer and the error bits via the MMM
LSR until the FIFO is empty, or (2) read successive data words (knowing there were no errors in the FIFO) until
the trigger count is met.
A similar sequence occurs when data flows in the other direction (from host through transmit FIFO), except
there is no error bit manipulation/checking involved.
FIFO Operation
The 16-byte transmit and receive data FIFOs are enabled by the FIFO Control Register (FCR) bit-0. You
can set the receive trigger level via FCR bits 6/7. The receiver FIFO section includes a time-out function to
ensure data is delivered to the external host. An interrupt is generated whenever the Receive Holding
Register (RHR) has not been read following the loading of a character or the receive trigger level has been
reached.
Receive (RX) FIFO
The RX FIFO can be configured to be 16 words deep and 11 bits wide. Each word in the RX FIFO consists
of 8 data bits and 3 error bits. The RX block of the MMM contains read and write pointers and status flag
circuitry that need only to be presented with data (for input), reset, read/write control signals, and read/write
clock signals. The RX block of the MMM internally manages the FIFO register file and pointers, and it
provides simultaneous read/write capability (no contention problems).
The RX block of the MMM provides data (for output), FIFO full flag, FIFO empty flag, and an almost full flag
which uses an associated predefined trigger level (obtained from the MMM FCR control register) to signal
when the trigger level has been met. Four possible trigger levels may be selected by programming bits 6-7
of the FCR control register.
A typical (interrupt driven) write to the RX block is a two-step process. The MMM micro-controller must first
write the 3 error bits to a shadow MMM LSR status register. Next, the micro-controller writes the data to
the RX FIFO and during this write operation, the 3 error bits are directly loaded from the LSR shadow
register into the bits 8-10 of the selected (11 bit-wide) FIFO register. These error bits represent the parity
error, framing error, and break interrupt signals associated with each data work transmission into the
receive FIFO. When the receive FIFO is read, these error bits are loaded directly into bits 2-4 of the MMM
LSR register.

Time Out Interrupts
The interrupts are enabled by IER bits 0-3. Care must be taken when handling these interrupts. Following a
reset the transmitter interrupt is enabled, the SocketModem will issue an interrupt to indicate that transmit
holding register is empty. This interrupt must be serviced prior to continuing operations.
The LSR register provides the current singular highest priority interrupt only. A condition can exist where a
higher priority interrupt may mask the lower priority interrupt(s). Only after servicing the higher pending
interrupt will the lower priority interrupt(s) be reflected in the status register. Servicing the interrupt without
investigating further interrupt conditions can result in data errors. When two interrupt conditions have the
same priority, it is important to service these interrupts correctly.
Receive Data Ready and Receive Time Out have the same interrupt priority (when enabled by IER bit-3).
The receiver issues an interrupt after the number of characters received have reached the programmed
trigger level. In this case the MMM FIFO may hold more characters than the programmed trigger level.
Following the removal of a data byte, the user should recheck LSR bit-0 for additional characters. A
Receive Time Out will not occur if the receive FIFO is empty. The time out counter is reset at the center of
each stop bit received or each time the receive holding register (RHR) is read.

RBR – Receive Buffer (RX FIFO)
All eight bits are used for receive channel data (host read/data in; host write/data out). The three error bits
per byte are copied into bits 2, 3, and 4 of the LSR during each host I/O read; therefore, they are available
for monitoring on a per-byte basis.
THR – Transmit Holding Register (TX FIFO)
All eight bits are used for transmit channel data (host write/data out; host read/data in).
IER – Interrupt Enable
Bits 4–7: Reserved and will always read 0.
Bits 0-3: Set by host software only and cleared by software control or host reset.
Bit 3: Enables modem status IRQ. If bits 0–3 of the MSR are set and this bit is set to 1 (enabled), a
host interrupt is generated.
Bit 2: Enables receive line status IRQ. If bits 1–4 (overrun, parity, framing, break errors) of the LSR
are set and this bit is set to a logic 1, a host interrupt is generated.
Bit 1: Enables transmit holding register IRQ. If bit 5 (transmit holding register empty) of the LSR is set
and this bit is set to a 1, a host interrupt is generated.
Bit 0: Enables received data available IRQ. If bit 0 (data ready) of the LSR is set and this bit is set to a
1, a host interrupt is generated.

Multi-Tech Systems, Inc. Universal Socket Hardware Guide for Developers (S000342P) 144
IIR – Interrupt Identification (Read Only)
Bits 6–7: (FIFO enabled bits). These bits will read a 1 if FIFO mode is enabled and the 16450 enable bit
is 0 (no force of 16450 mode).
Bits 4–5: Reserved and always read a 0.
Bits 1–3: Interrupt ID bits.
Bit 0: Interrupt pending. If logic 0 (in default mode), an interrupt is pending.
When the host accesses IIR, the contents of the register are frozen. Any new interrupts will be recorded,
but not acknowledged during the IIR access. This requires buffering bits (0–3, 6–7) during IIR reads.

Bits 6–7: Used to determine RX FIFO trigger levels.
Bit 5: Used to detect a change in the FCR.
Bit 4: TX FIFO overrun bit.
Bit 3: DMA mode select. Must be set to zero. When bit 3 is a 0, the 16450 mode is enabled which
does only single-byte transfers.
Bit 2: TX FIFO reset. This will cause TX FIFO pointer logic to be reset (any data in TX FIFO will be
lost). This bit is self clearing; however, a shadow bit exists that is cleared only when read by the
host, thus allowing the host to monitor a FIFO reset.
Bit 1: RX FIFO reset. This will cause RX FIFO pointer logic to be reset (any data in RX FIFO will be
lost). This bit is self clearing; however, a shadow bit exists that is cleared only when read by the
host, thus allowing the host to monitor a FIFO reset.
Bit 0: FIFO enable. The host writes this bit to logic 1 to put the block in FIFO mode. This bit must be a
1 when writing other bits in this register or they will not be programmed. When this bit changes
state, any data in the FIFOs or the RBR and THR registers will be lost and any pending
interrupts are cleared.

LCR – Line Control
Bit 7: Divisor latch access bit. This bit allows the host, access to the divisor latch. Under normal
circumstances, the bit is set to 0 (provides access to the RX and TX FIFOs at address 0). If the
bit is set to 1, access to transmitter, receiver, interrupt enable, and modem control registers is
disabled. In this case, when an access is made to address 0, the divisor latch least (DLL)
significant byte is accessed. Address 1 accesses the most significant byte (DLM). Address 7
accesses the DLX divisor latch register. Address 4 accesses the MCX status/control register.
Bit 6: Used to denote a host-generated set break condition.
Bits 0,1,3,4,5: Used only in parity bit generation for the 7 bit data byte case. Bits 0 and 1 are used for
word length select (b0 = 0 and b1 = 1 is used for 7 bit data). Bit 3 is parity enable. Bit 4 is even
parity select. Bit 5 is stick parity.

MCR – Modem Control
Bits 5–7: Reserved, and will always be 0.
Bit 3: Controls the signal used to 3-state the host interrupt. If 0, then an active-low L33xV output will
be set to 0, and this signal will be used to 3-state the host interrupt output pin.
Bits 0–2: Reserved.
Bit 2: OUT1.
Bit 1: Request to Send (RTS).
Bit 0: Data terminal ready (DTR).
LSR – Line Status
Bit 7: Error in RX FIFO. This bit is always set to 1 if at least one data byte in the RX FIFO has an
error. This will clear when there are no more errors in the RX FIFO.
Bit 6: Transmitter empty. This bit is the same as LSR bit 5 (THRE) in MMM
Bit 5: Transmitter holding register empty. This bit is set to 1 when either the transmitter holding
register has been read (emptied) by the micro-controller (16450 mode) or the TX FIFO is empty
(16550 mode). This bit is set to 0 when either the THR or the TX FIFO becomes not empty in
16450 mode. In 16550 mode, it is set to 0 only after the trigger level has been met since the
last occurrence of TX FIFO empty. If the transmitter timer is enabled, a shadow bit exists which
delays the timer setting this bit to 1. When reading this bit, the micro-controller will not see the
delay. Both shadow and register bits are cleared when the host writes to the THR or TX FIFO in
16450 mode. The trigger level must be reached to clear the bit in 16550 (FIFO) mode.
Bits 2–4: Used for parity error, framing error, and break detect. These bits are written, indirectly, by the
micro-controller as follows: The bits are first written to the shadow bit locations when the micro-
controller write accesses the LSR. When the next character is written to the receive buffer
(RBR) or the RX FIFO, the data in the shadow bits is then copied to the RBR (16450 mode) or
RX FIFO (16550 mode). In FIFO mode, bits become available to the host when the data byte
associated with the bits is next to be read. In FIFO mode, with successive reads of the receiver,
the status bits will be set if an error occurs on any byte. Once the micro-controller writes to the
RBR or RX FIFO, the shadow bits are auto cleared. The register bits are updated with each host
read.
Bit 1: Overrun error. This bit is set if the micro-controller makes a second write to RBR before the host
reads data in the buffer (16450 mode) or with a full RX FIFO (16550 mode). No data will be
transferred to the RX FIFO under these circumstances. This bit is reset when the host reads the
LSR.
Bit 0: Data ready bit. This bit is set to 1 when received data is available, either in the RX FIFO (16550
mode) or the RBR (16450 mode). This bit is set immediately upon the micro-controller writing
data to the RBR or FIFO if the receive timer is not enabled, but it is delayed by the timer interval
if the receive timer is enabled. For micro-controller read access, a shadow bit exists so that the
micro-controller does not see the delay that the host sees. Both bits are cleared to logic 0
immediately upon reading all data in either RBR or RX FIFO.
MSR – Modem Status
Bits 4 through 7 of the MSR can also take on the MCR bits 0 through 3 value when in MCR loop mode (i.e.
when MCR b4 = 1). The transfer of bits in loop back has a null modem twist (i.e. MCR b0 goes to MSR b5
and MCR b1goes to MSR b4).
Bit 7: Data carrier detect (DCD) bit.
Bit 6: Ring indicator (RI) bit.
Bit 5: Data set ready (DSR) bit.
Bit 4: Clear to send (CTS) bit.
Bit 3: Delta data carrier detect pin. This bit is set to a 1 whenever the data carrier detect bit changes
state. It is reset when the host reads the modem status register.
Bit 2: Trailing edge ring indicator bit. This bit is set to 1 on the falling edge of the ring indicator bit. It is
reset when the host reads the modem status register.
Bit 1: Delta data set ready bit. This bit is set to 1 whenever the data set ready changes state. It is
reset when the host reads the modem status register.
Bit 0: Delta clear to send bit. This bit is a one whenever the clear to send bit changes state. It is reset
when the host reads the modem status register.

SCR – Scratch
The host programmer uses this register for temporary data storage.
DLL – Divisor Latch (LSByte)
This register contains low-order byte for the 16-bit clock divider. It is kept to maintain register set
compatibility with the 16C550A interface. However, it is not used for clock generation since MMM does not
require the generation of a real baud clock.
DLM – Divisor Latch (MSByte)
This register contains high-order byte for the 16-bit clock divider. It is kept to maintain register set
compatibility with the 16C550A interface. However, it is not used for clock generation, since MMM does not
require the generation of a real baud clock.
Programming the Baud Rate Generator Registers DLM (MSB) and DLL (LSB) provides a user capability for
selecting the desired final baud rate. The example in the Table below shows the selectable baud rates
available when using a 1.8432 MHz external clock input.

Important – Tooling Holes for Mounting
Hardware on the Board
It is recommended that nylon hardware be used if the SocketModems are to be mounted on the board using the
two tooling holes on the board due to possible traces and vias around the tooling holes.
For the MT5692SMI Analog SocketModem:
#2 or M2 for hardware should be used for mounting the analog modem on the board when the tooling hole
diameter on the board is .093.
#4 or M3 for hardware should be used for mounting the analog modem on the board when the tooling hole
diameter on the board is .128.

RESET I Device Reset (with pull-up). The active low –RESET input resets the device logic and returns the
configuration of the device to the original factory default values or "stored values" in the NVRAM.
–RESET is tied to VCC through a time-constant circuit for “Power-on-Reset” functionality. The
SocketModem is ready to accept commands after a fixed amount of time (“X” Time) after power-on or
reset.
Model Time Constant "X" Time Minimum Reset Pulse*
MT5692SMI 250 ms 6 seconds 100us
*The SocketModem device may respond to a shorter reset pulse.
Reset Line Interface for the MT5692SMI. The modem’s reset line employs a 10K pull up resistor. If
an open collector driver is to be used, run that output to the modem only and use a separate driver for
other embedded components. The modem’s reset signal may also be driven by a circuit that both
sinks and sources current if desired. It is also important to note that these modems do not require an
external reset. They have their own internal reset circuitry and voltage monitor and will function
correctly even if the reset input is open.
Modem Reset (with weak pull-up). The active low –RESET input resets the SocketModem logic and
returns the AT command set to the original factory default values or to "stored values" in NVRAM. The
modem is ready to accept commands within 6.5 seconds of power-on or reset. Reset must be
asserted for a minimum of 300 ns.

SocketModem Parallel Interface
The modem supports a 16550A interface in parallel interface versions. The 16550A interface can operate in FIFO mode or
non-FIFO mode. Non-FIFO mode is the same as the 16450-interface operation. FIFO mode’s unique operations are
described in this chapter.
Overview
The modem emulates the 16450/16550A interface and includes both a 16-byte receiver data first-in first-out buffer
(RX FIFO) and a 16-byte transmit data first-in first-out buffer (TX FIFO).
FIFO Mode Selected
When FIFO mode is selected in the FIFO Control Register (FCR0 = 1), both FIFOs are operative.
FIFO Mode Not Selected
When FIFO mode is not selected, operation is restricted to a 16450-interface operation.
Receive Data
Received Data is read by the host from the Receiver Buffer (RX Buffer). The RX Buffer corresponds to the
Receiver Buffer Register in a 16550A device. In FIFO mode, the RX FIFO operates transparently behind the RX
Buffer. Interface operation is described with reference to the RX Buffer in FIFO and non-FIFO modes.
Transmit Data
Transmit Data is loaded by the host into the Transmit Buffer (TX Buffer). The TX Buffer corresponds to the
Transmit Holding Register in a 16550A device. In FIFO mode, the TX FIFO operates transparently behind the
TX Buffer. Interface operation is described with reference to the TX Buffer in both FIFO and non-FIFO modes.
Receiver FIFO Interrupt Operation
Receiver Data Available Interrupt
When the FIFO mode is enabled (FCR0 = 1) and receiver interrupt (RX Data Available) is enabled (IER0 =
1), receiver interrupt operation is as follows:
1. The Receiver Data Available Flag (LSR0) is set as soon as a received data character is available in the
RX FIFO. LSR0 is cleared when RX FIFO is empty.
2. The Receiver Data Available Interrupt code (IIR0-IIR4 = 4h) is set whenever the number of received
data bytes in the RX FIFO reaches the trigger level specified by FCR6-FCR7 bits. It is cleared
whenever the number of received data bytes in the RX FIFO drops below the trigger level specified by
FCR6-FCR7 bits.
3. The HINT interrupt is asserted whenever the number of received data bytes in the RX FIFO reaches
the trigger level specified by FCR6-FCR7 bits. HINT interrupt is de-asserted when the number of
received data bytes in the RX FIFO drops below the trigger level specified by FCR6-FCR7 bits.
Receiver Character Timeout Interrupts
When the FIFO mode is enabled (FCR0 = 1) and receiver interrupt (Receiver Data Available) is enabled
(IER0 = 1), receiver character timeout interrupt operation is as follows:
1. A Receiver character timeout interrupt code (IIR0-IIR3 = Ch) is set if at least one received character is
in the RX FIFO, the most recent received serial character was longer than four continuous character
times ago (if 2 stop bits are specified, the second stop bit is included in this time period), and the most
recent host read of the RX FIFO was longer than four continuous character times ago.
Transmitter FIFO Interrupt Operation
Transmitter Empty Interrupt
When the FIFO mode is enabled (FCR0 = 1) and transmitter interrupt (TX Buffer Empty) is enabled (IER0
=1), transmitter interrupt operation is as follows:
1. The TX Buffer Empty interrupt code (IIR0-IIR3 = 2h) will occur when the TX Buffer is empty. It is
cleared when the TX Buffer is written to (1 to 16 characters) or the IIR is read.
2. The TX Buffer Empty indications will be delayed 1 character time minus the last stop bit time whenever
the following occur: THRE = 1 and there have not been at least two bytes at the same time in the TX
FIFO Buffer since the last setting of THRE was set. The first transmitter interrupt after setting FCR0 will
be immediate.

IER – Interrupt Enable Register
(Addr = 1, DLAB = 0)
The IER enables five types of interrupts that can separately assert the HINT output signal (See the Interrupt
Sources and Reset Control table in the IIR section of this chapter). A selected interrupt can be enabled by
setting the corresponding enable bit to a 1, or disabled by setting the corresponding enable bit to a 0. Disabling
an interrupt in the IER prohibits setting the corresponding indication in the IIR and assertion of HINT. Disabling
all interrupts (resetting IER0 – IER3 to a 0) inhibits setting of any Interrupt Identifier Register (IIR) bits and
inhibits assertion of the HINT output. All other system functions operate normally, including the setting of the
Line Status Register (LSR) and the Modem Status Register (MSR).

Bits 7-4 Not used.
Always 0.
Bit 3 Enable Modem Status Interrupt (EDSSI).
This bit, when a 1, enables assertion of the HINT output whenever the Delta CTS (MSR0), Delta
DSR (MSR1), Delta TER (MSR2), or Delta DCD (MSR3) bit in the Modem Status Register (MSR) is
a 1. This bit, when a 0, disables assertion of HINT due to setting of any of these four MSR bits.
Bit 2 Enable Receiver Line Status Interrupt (ELSI).
This bit, when a 1, enables assertion of the HINT output whenever the Overrun Error (LSR1), Parity
Error (LSR2), Framing Error (LSR3), or Break Interrupt (LSR4) receiver status bit in the Line Status
Register (LSR) changes state. This bit, when a 0, disables assertion of HINT due to change of the
receiver LSR bits 1-4.
Bit 1 Enable Transmitter Holding Register Empty Interrupt (ETBEI).
This bit, when a 1, enables assertion of the HINT output when the Transmitter Empty bit in the Line
Status Register (LSR5) is a 1.This bit, when a 0, disables assertion of HINT due to LSR5.
Bit 0 Enable Receiver Data Available Interrupt (ERBFI) and Character Timeout in FIFO Mode.
This bit, when a 1, enables assertion of the HINT output when the Receiver Data Ready bit in the
Line Status Register (LSR0) is a1 or character timeout occurs in the FIFO mode. This bit, when a 0,
disables assertion of HINT due to the LSR0 or character timeout.

(the modem operates in non-DMA mode in 16450 operation).
DMA Operation in FIFO Mode – Not Supported
Non-DMA Operation in FIFO Mode
RXRDY will be asserted when there are one or more characters in the RX FIFO. RXRDY
will go inactive when there are no more characters in the RX FIFO.
TXRDY will be asserted when there are no characters in the TX FIFO. TXRDY will go
inactive when the character is loaded into the TX FIFO Buffer.
Bit 2 TX FIFO Reset
When FCR2 is a 1, all bytes in the TX FIFO are cleared. This bit is cleared automatically by the
modem.
Bit 1 RX FIFO Reset
When FCR1 is a 1, all bytes in the RX FIFO are cleared. This bit is cleared automatically by the
modem.
Bit 0 FIFO Enable
When FCR0 is a 0, 16450 mode is selected and all bits are cleared in both FIFOs. When FCR0
is a 1, FIFO mode (16550A) is selected and both FIFOs are enabled. FCR0 must be a 1 when
other bits in the FCR are written or they will not be acted upon.

IIR – Interrupt Identifier Register
(Addr = 2)
The Interrupt Identifier Register (IIR) identifies the existence and type of up to five prioritized pending interrupts.
Four priority levels are set to assist interrupt processing in the host. The four levels, in order of decreasing
priority, are Highest: Receiver Line Status, 2: Receiver Data Available or Receiver Character Timeout. 3: TX
Buffer Empty, and 4: Modem Status.
When the IIR is accessed, the modem freezes all interrupts and indicates the highest priority interrupt pending
to the host. Any change occurring in interrupt conditions are not indicated until this access is complete.
Bits 7-6 FIFO Mode
These two bits copy FCR0.
Bits 5-4 Not Used
Always 0.
Bits 3-1 Highest Priority Pending Interrupt
These three bits identify the highest priority pending interrupt (Table below). Bit 3 is
applicable only when FIFO mode is selected; otherwise, bit 3 is a 0.
Bit 0 Interrupt Pending
When this bit is a 0, an interrupt is pending; IIR bits 1-3 can be used to determine the source
of the interrupt. When this bit is a 1, an interrupt is not pending

LCR – Line Control Register
(Addr = 3)
The Line Control Register (LCR) specifies the format of the asynchronous data communications exchange.
Bit 7 Divisor Latch Access Bit (DLAB)
This bit must be set to a 1 to access the Divisor Latch Registers during a read or write operation.
It must be reset to a 0 to access the Receiver Buffer, the Transmitter Buffer, or the Interrupt
Enable Register.
Bit 6 Set Break
When bit 6 is a 1, the Transmit data is forced to the break condition, i.e., space (0) is sent. When
bit 6 is a 0, break is not sent. The Set Break bit acts only on the Transmit data and has no effect
on the serial in logic.
Bit 5 Stick Parity
When Parity is enabled (LCR3 = 1) and stick parity is selected (LCR5 = 1), the parity bit is
transmitted and checked by the receiver as a 0 if even parity is selected (LCR4 – 1) or a 1 if odd
parity is selected (LCR4 = 0). When the stick parity is not selected (LCR3 = 0), parity is transmit
and checked as determined by the LCR3 and LCR4 bits.
Bit 4 Even Parity Select (EPS)
When parity is enabled (LCR3 = 1) and stick parity is not selected (LCR5 = 0), the number of 1s
transmitted or checked by the receiver in the data word bits and parity bit is either even (LCR4 =
1) or odd (LCR4 = 0).
Bit 3 Enable Parity (PEN)
When bit 3 is a 1, a parity bit is generated in the serial out (transmit) data stream and checked in
the serial in (receive) data stream as determined by the LCR4 and LCR5 bits. The parity bit is
located between the last data bit and the first stop bit.
Bit 2 Number of Stop GBITS (STB)
This bit specifies the number of stop bits in each serial out character. If bit 2 is a 0, one stop bit is
generated regardless of word length. If bit 2 is a 1 and 5-bit word length is selected, one and
one-half stop bits are generated. If bit 2 is a 1 and 6-, 7-, or 8-bit word length is selected, two
stop bits are generated. The serial in logic checks the first stop bit only, regardless of the number
of stop bits selected.
Bit 1-0 Word Length Select (WLS0 and WLS1)
These two bits specify the number of bits in each serial in or serial out character. The encoding
of bits 0 and 1 is:
Bit 1 Bit 0 Word Length
0 0 5 Bits (Not supported)
0 1 6 Bits (Not supported)
10 7 Bits

LSR – Line Status Register
(Addr = 5)
This 8-bit register provides status information to the host concerning data transfer
Bit 7 RX FIFO Error
In the 16450 mode, this bit is not used and is always 0.
In the FIFO mode, this bit is set if there are one or more characters in the RX FIFO with parity
error, framing error, or break indication detected. This bit is reset to a 0 when the host reads the
LSR and note of the above conditions exist in the RX FIFO.
Bit 6 Transmitter Empty (TEMT)
This bit is set to a 1 whenever the TX Buffer (THR) and equivalent of the Transmitter Shift
Register (TRS) are both empty. It is reset to a 0 whenever either the THR or the equivalent of the
TSR contains a character.
In the FIFO mode, this bit is set to a 1 whenever the TX FIFO and the equivalent of the TSR are
both empty
Bit 5 Transmitter Holding Register Empty (THRE) [TX Buffer Empty]
This bit, when set, indicates that the TX Buffer is empty and the modem can accept a new
character for transmission. In addition, this bit causes the modem to issue an interrupt to the host
when the Transmit Holding Register Empty Interrupt Enable bit (IIR1) is set to 1. The THRE bit is
set to a 1 when a character is transferred from the TX Buffer. The bit is reset to 0 when a byte is
written into the TX Buffer by the host.
In the FIFO mode, this bit is set when the TX FIFO is empty; it is cleared when at least one byte
is in the TX FIFO.
Bit 4 Break Interrupt (BI)
This bit is set to a 1 whenever the received data input is a space (logic 0) for longer than two full
word lengths plus 3 bits. The BI is reset when the host reads the LSR.
Bit 3 Framing Error (FE)
This bit indicates that the received character did not have a valid stop bit. The FE bit is set to a 1
whenever the stop bit following the last data bit or parity bit is detected as a logic o (space). The
FE bit is reset to a 0 when the host reads the LSR.
In the FIFO mode, the error indication is associated with the particular character in the FIFO it
applies to. The FE bit set to a 1 when this character is loaded into the RX Buffer.
Bit 2 Parity Error (PE)
This bit indicates that the received data character in the RX Buffer does not have the correct
even or odd parity, as selected by the Even Parity Select bit (LCR4) and the Stick Parity bit
(LCR5). The PE bit is reset to a 0 when the host reads the LSR.
In the FIFO mode, the error indication is associated with the particular character in the FIFO it
applies to. The PE bit set to a 1 when this character is loaded into the RX Buffer.
Bit 1 Overrun Error (OE)
This bit is set to a 1 whenever received data is loaded into the RX Buffer before the host has
read the previous data from the RX Buffer. The OE is reset to a 0 when the host reads the LSR.
In the FIFO mode, if data continues to fill beyond the trigger level, an overrun condition will occur
only if the RX FIFO is full and the next character has been completely received.
Bit 0 Receiver Data Ready (DR)
This bit is set to a 1 whenever a complete incoming character has been received and transferred
into the RX Buffer. The DR bit is reset to a 0 when the host reads the RX Buffer.
In the FIFO mode, the DR bit is set when the number of received data bytes in the RX FIFO
equals or exceeds the trigger level specified in the FCR0-FCR1.

Multi-Tech Systems, Inc. Universal Socket Hardware Guide for Developers (S000342P) 169
MSR – Modem Status Register
(Addr = 6)
The Modem Status Register (MSR) reports current state and change information of the modem. Bits 4-7 supply
current state and bits 0-3 supply change information. The change bits are set to a 1 whenever a control input
from the modem changes state from the last MSR read by the host. Bits 0-3 are reset to 0 when the host reads
the MSR or upon reset.
Whenever bits 0, 1, 2, or 3 are set to a 1, a Modem Status Interrupt (IIR0-IIR3 = 0) is generated.
Bit 7 Data Carrier Detect (DCD)
This bit indicates the logic state of the DCH# (RLSD#) output.
Bit 6 Ring Indicator (RI)
This bit indicates the logic state of the RI# output.
Bit 5 Data Set Ready (DSR)
This bit indicates the logic state of the DSR# output.
Bit 4 Clear to Send (CTS)
This bit indicates the logic state of the CTS# output.
Bit 3 Delta Data Carrier Detect (DDCD)
This bit is set to a 1 when the DCD bit changes state since the host last read the MSR.
Bit 2 Trailing Edge of Ring Indicator (TERI)
This bit is set to a 1 when the RI bit changes from a 1 to a 0 state since the host last read the
MSR.
Bit 1 Delta Data Set Ready (DDSR)
This bit is set to a 1 when the DSR bit has changed since the host last read the MSR.
Bit 0 Delta Clear to Send (DCTS)
This bit is set to a 1 when the CTS bit has changed since the MSR the host last read the MSR.
RBX – RX Buffer (Receiver Buffer Register)
(Addr = 0, DLAB = 0)
The RX Buffer (RBR) is a read-only register at location 0 (with DLAB = 0). Bit 0 is the least significant bit of the
data and is the first bit received.
THR – TX Buffer (Transmitter Holding Register)

Introduction
The Multi-Tech SocketModem MT2492SMI-xx utilizes the LSI CVxx Controller Based Modem Devices and the LSI CSP104
Silicon Direct Access Arrangement (DAA) to form a 2-chip complete embedded modem. This solution includes a DSP data
pump, modem controller, on-chip RAM and ROM, codec, DAA, analog output, and 24.576 MHz clock input.
The modem accepts standard modem AT commands and provides connect rates up to 56 Kbps full-duplex over the Public
Switched Telephone Network (PSTN) and features a complete set of modem protocols including all ITU-T standard formats
up to V.92.
To provide the most flexibility, the CVxx modem system-side device provides numerous additional features for embedded
modem applications. It includes call progress monitoring through standard result codes, error correction, data compression,
autobaud, and fast connect modes. In addition, because the CVxx modem integrates the DAA, analog features (such as line-
in use and over current detection) are included.
This device is ideal for embedded modem applications due to its simple host interface, small board space, and low power

The Windows-Based Auto-Discovery Manager
The Auto-Discovery Manager is a mechanism for remotely monitoring the Universal IP functioning. It also provides
support for configuring several key parameters, such as DHCP Status (enable/disable), IP Address, and the Host
Name of an MT100SEM-IP.
The Auto-Discovery mechanism is utilized by running a Windows-based Server Application that can
monitor/configure the MT100SEM-IP. Communication between the MT100SEM-IP and the Windows-based Server is
through MAC level broadcasts on a configured UDP port.
Two Ways to Use Auto Discovery: Auto-Discovery can be performed by using AT Commands (see the Universal
IP AT Commands Reference Guide – included on the Universal Kit CD) or by using the Auto-Discover Manager
Software (also included on the Universal Kit CD).
Auto-Discovery Manager Software
The Auto-Discovery Manager is composed of two components:
xThe Client Component – The Client component periodically broadcasts its current configuration over
the network.
xThe Server Component – The Server component receives the broadcasts from the client.
Client Component
The Auto-Discovery Client component is integrated with MT100SEM-IP. It broadcasts its current configuration
over the network on a specific UDP SERVER-PORT. By default the SERVER-PORT is set to 1020. The
configuration parameters broadcast are
xVersion details
xMAC Address
xStatic IP Address
xDHCP Status
xDHCP Assigned IP Address
xHost Name
xBroadcast interval
xPort number on which the client listens
Auto-Discovery Manager Software – Server Component
The server component provides server side support software for the remote user. It listens on the SERVER-
PORT and receives the broadcasts from the client and updates the list of configuration parameters. This list can
be viewed through the User Interface:

How to View the Detailed Information
New entries are appended to the list shown on the screen above. Only the first ten entries are displayed on
the screen. However the administrator can scroll down to view more entries. Clicking on an entry displays
the detailed information about that entry.
How to Edit the List and Make the Changes Permanent
1. Double-click on the entry you wish to edit.
2. After clicking the desired entry, a new dialog box displays showing the current configuration.
3. Enter the new parameters and click the SET button. The server sends the modified parameters to the
client.
Upon receiving the broadcast from the Server, the Client validates the packet. The Client determines
whether the packet is destined for its own MAC Address. If so, it sets the modified parameters that are
different from its current configuration, and the it broadcast the newly configured parameters.
The Client Status is set to Active upon the receipt of a broadcast packet.
The Client Status is made Inactive if there is no request from the client for a stipulated period.
(3 * periodic timer value).
How to Set the Parameters to the Previous Configuration
When the RESET button is clicked, the parameters are set to the defaults received. In other words, RESET
is similar to UNDO (it sets the modifications to the previous ones).
Saving the Log
The logs can be saved to a file. They are spooled into the third part of the window in the main dialog box. To save

Regulatory Requirements for the Wi-Fi Antenna
This section covers how to use the modular transmitter in order to maintain the modular transmitter approval and RF
exposure compliance.
Conditions to Satisfy Modular Transmitter Approval
This device is intended only for use by OEM integrators under the following 3 conditions:
1. The antenna must be installed such that 20 cm is maintained between the antenna and the end
user for all installations.
2. The transmitter module may not be located with any other transmitter or antenna.
3. The communications device is approved using the FCC "unlicensed modular transmitter approval"
method. Therefore, the communication device must only be used with the originally approved
antennas.
As long as the 3 conditions above are met, further transmitter testing will not be required. However, the
OEM integrator is still responsible for testing their end-product for any additional compliance requirements
with this communication device installed (for example, digital device emissions, PC peripheral
requirements, etc.)
IMPORTANT NOTE: In the event that any of these conditions CANNOT be met (for example certain laptop
configurations, location with another transmitter, or use of a different type antenna), then the FCC
authorization for the communications device is no longer considered valid and the FCC ID CANNOT be
used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating
the end product (including the transmitter) and obtaining a separate FCC authorization.
RF Exposure Statements Developers Must Include in the User Manual for End Users
The user manual for consumers must include the following information in a prominent location:
IMPORTANT NOTE: To comply with FCC RF safety exposure limits, the antenna used for this transmitter
must be installed to provide a separation distance of at least 20 cm from all persons and must not be
located or operating in conjunction with any other antenna or transmitter.
Regulatory Requirements for End Product Labelling
Suggested End Product Labeling
This transmitter module is authorized only for use in devices where the antenna may be installed in such a
way that 20 cm may be maintained between the antenna and the users (for example access points, routers,
cellular ASDL modems, and similar equipment). The final end product must be labeled in a visible area on
the exterior of the enclosure with the following or similar text: "Contains TX FCC ID: AU792U07B06821".
FCC & IC Information to Consumers
The user manual for the consumer must contain the statements required by the following FCC and IC
regulations: 47 C.F.R. 15.19(a)(3), 15.21, 15.101 and RSS-Gen Issue 2 dated June 2007, Sections 7.1.4
and 7.1.5.
Additional Information That Must Be Provided to OEM Integrators
The end user should NOT be provided any instructions on how to remove or install the modular transmitter.

Chapter 14 – SocketWireless® Bluetooth®
(MTS2BTSMI)
Introduction
The Multi-Tech Systems, Inc. SocketWireless® with Bluetooth®-enabled technology allows developers to establish cellular
networks using a special set of AT commands. The SocketWireless with Bluetooth technology makes the cable-replacement
transition to cellular networks seamless and easy.
This chapter explains how to establish Bluetooth communication between two serial devices for data applications in a point-
to-point network. Bluetooth-enabled devices create communication-ready devices by integrating data functionality into a
single, universal socket design. This complete, ready-to-integrate device dramatically reduces development time and costs for
system designers.
Notes about Byte Gaps and Data Latency
Because of the way Bluetooth is designed and operates, random byte gaps of 5 ms to 20 ms are common. Packet size
will vary from transmission to transmission.
Although the serial band frequency operates up to 920K bps, effective data throughput in fast streaming mode is
approximately 200K bps. Effective data throughput in regular data mode is 60K bps. The reason for the slower speed
in regular mode is due to the AT parser, which looks at each character for ASCII valid command scripts in the regular
mode's data stream.
The SocketWireless RX has very limited buffering, so if you do not use hardware flow control and are transmitting
further distances, you will quickly overflow the 50 byte buffer because of RF retransmissions, etc.
When a Bluetooth connection is made, the SocketWireless device goes into regular data mode per the power-up
factory default settings. This enables the user to configure the SocketWireless settings remotely via a remote RF
Bluetooth connection. Basically, you can setup the SocketWireless device so no commands are required to be sent
from the embedded side of the device. This allows seamless interfacing with legacy systems without the need to
modify the host device

6. Send Data.
Note: When sending commands from the Slave when the Slave connects in Fast Data Mode (ATSW25/or issuing
ATMF). All valid AT commands are sent through the Slaves UART will be interpreted and responded by the Master
radio as if it was the local Slave radio. Basically in this configuration from the Slave end you can obtain status and
configure from the remote Master radio. This is a unique feature that may be useful in some applications but can
confuse the user if you think you are talking to the local Slave UART.
To Get Out of Data Mode and Check Status:
1. Delay at least 50 milliseconds; this could be less or more.
2. Get into Command Mode.

ATSW23,3,x,x ATSW23,7,x,x
Disabling Flow Control Using Protocol V.2.0
Using a terminal screen with flow control enabled, issue commands to turn off flow control.
Sent: ATSW22,7,1,0 <cr> // Set PIO7 as output and do not store in flash
Reply: OK<cr_lf>
Sent: ATSW23,7,1,0<cr> // Set PIO7 output high and do not store in flash
Reply: OK<cr_lf>
To store the setting in flash:
Sent: ATSW22,7,1,1<cr> // Set PIO7 as output and store in flash
Reply: OK<cr_lf>
Sent: ATSW23,7,1,1<cr> // Set PIO7 output high and store in flash
Reply: OK<cr_lf>
Now you can communicate with the Bluetooth device with flow control turned off.

xRepeater Example Using the SocketWireless MTS2BTSMI or the Bluetooth Adapter MT2BTA.
Changing Configuration
Parameters, such as the Bluetooth Name, Service Name, Class of Device, and Serial Port settings can be viewed
and configured. This can be done locally through the serial port UART or from a remote Bluetooth RF link. To
configure the SocketWireless Bluetooth device, the device must be in command mode by issuing +++.
You can use the developer board and the RS-232 cable to connect to a PC and pass ASCII characters through the
terminal to the SocketWireless Bluetooth device. The communications settings should match the settings used when
the SocketWireless Bluetooth device connects. For example, the defaults are:
9600bps
8 bits
No Parity
1 stop bit
Hardware flow control enabled.
Once you change these parameters, you have the option to store them permanently in the non-volatile memory. Run
your favorite terminal emulator, HyperTerminal, or other program.
xType AT on your screen and follow it with a carriage return <cr_lf>. You should see "OK" returned to you.
This will verify that your cable and communications settings are correct. When the SocketWireless device is
not connected to another Bluetooth device, you can type the AT commands directly into the
SocketWireless' UART; e.g., you do not have to type +++ to change from data mode to command mode.
xNow you can enter any of the AT commands discussed in the following sections. Follow these commands
by <cr_lf>. Valid commands will return an "OK" or a valid response. Invalid commands will reply ERROR.
xTo return to data mode, type ATMD. You can now pass or receive data from a remote connected Bluetooth
device.
Notes:
xIf you change communications parameter settings, remember to change your terminal or emulator
communications settings to correspond to the newly created parameter settings.
xAT commands will not echo back to the terminal.
