1. Overview
The AC4490 is a member of AeroComm’s ConnexRF OEM transceiver family. It is designed for
integration into OEM systems operating under FCC part 15.247 regulations for the 900 MHz ISM band.
The AC4490 is a cost-effective, high performance, 900 MHz frequency hopping spread spectrum
transceiver. It provides an asynchronous TTL level serial interface for OEM Host communications.
Communications include both system and configuration data. The Host supplies system data for
transmission to other Host(s). Configuration data is stored in an on-board EEPROM. All frequency
hopping, synchronization, and RF system data transmission/reception is performed by the transceiver.
The AC4490 transceivers can be used as a direct serial cable replacement – requiring no special Host
software for operation. They also feature a number of On-the-Fly Control Commands providing the
OEM Host with a very versatile interface for any situation.
AC4490 transceivers operate in a Point-to-Point or Point-to-Multipoint, Client-Server or Peer-to-Peer
architecture. One transceiver is configured as a Server and there can be one or many Clients. To
establish synchronization between transceivers, the Server emits a beacon. Upon detecting a beacon,
a Client transceiver informs its Host and a RF link is established.
This document contains information about the hardware and software interface between an
AeroComm AC4490 transceiver and an OEM Host. Information includes the theory of operation,
specifications, interface definition, configuration information and mechanical drawing.
The OEM is responsible for ensuring the final product meets all FCC and/or appropriate regulatory
agency requirements listed herein before selling any product.

3.3 SYSTEM TIMING
Care should be taken when selecting transceiver architecture as it can have serious effects on data
rates, latency timings, and overall system throughput. The importance of these three characteristics
will vary from system to system and should be a strong consideration when designing the system.
3.3.1 Serial Interface Data Rate
The Serial Interface Data Rate is programmable by the Host. This is the rate the Host and transceiver
communicate over the serial bus. Possible values range from 1200 bps to 115,200 bps. The only
supported mode is asynchronous – 8-bit, No Parity, 1 Start Bit, and 1 Stop Bit.
AD Out is an unbuffered, high impedance output and must be buffered by the OEM Host when used.

4.2 EEPROM CONFIGURATION COMMANDS
The configuration set allows the Host to modify the operation of the transceiver. If the Command/Data
pin (Pin 17) is pulled logic Low, a transceiver will interpret incoming Host data as Command Data. The
Host can then read and write parameters using the various configuration commands listed below. To
exit Configuration Mode, the Host must perform a hardware or power-on reset or issue an Exit
Command Mode command to the transceiver.
2/18/03

AC4490 Specifications
4.2.1 EEPROM Byte Read
Upon receiving this command, a transceiver will transmit the desired data from the address requested
by the Host.
Host Command:
Byte 1 = C0h
Byte 2 = Address
Byte 3 = Length (01…FFh = 1…255 bytes; 00h = 256 bytes)
Transceiver Response:
Byte 1 = C0h
Byte 2 = Address
Byte 3 = Length
Byte 4…n = Data at requested address(s)
4.2.2 EEPROM Byte Write
Upon receiving this command, a transceiver will write the data byte to the address specified but will not
echo it back to the Host until the EEPROM write cycle is complete. The write can take as long as
10ms to complete. Following the write cycle, a transceiver will transmit the data byte to the Host.
Multiple byte EEPROM writes are allowed up to a length of 128 bytes. An EEPROM boundary exists
between addresses 7Fh and 80h. No single EEPROM write command shall write to addresses on
both sides of that EEPROM boundary.
Host Command:
Byte 1 = C1h

4.3 ON-THE-FLY CONTROL COMMAND REFERENCE
The AC4490 transceiver contains static memory that holds many of the parameters that control the
transceiver operation. Using the “CC” command set allows many of these parameters to be changed
during system operation. Because the memory these commands affect is static, when the transceiver
is reset, these parameters will revert back to the settings stored in the EEPROM. Do not to modify
undocumented static addresses as undesired operation may occur. All “CC” commands must be
issued from the Host to the transceiver with Command/Data (Pin 17) pulled logic Low. To exit “CC”
mode, simply take the Command/Data pin High.

After the Host issues the power-down command to the transceiver, the transceiver will de-assert the
In_Range line after entering power-down. A Client transceiver in power-down will remain in sync with a
Server for a minimum of 2 minutes. To maintain synchronization with the Server, this Client transceiver
should re-sync to the Server at least once every 2 minutes. This re-sync is accomplished by issuing
the Power-Down Wake-Up Command and waiting for the In Range line to go active. Once this occurs,
the Client transceiver is in sync with the Server and can be put back into power-down.

5. Theory of Operation
5.1 HARDWARE INTERFACE
Below is a description of all hardware pins used to control the AC4490.
5.1.1 GIn (Generic Inputs 0 and 1) (pins 4 and 14 respectively) and GOn
(Generic Outputs 0 and 1) (pins 1 and 9 respectively)
Both GIn pins, when enabled in EEPROM, serve as negative-going edge triggered generic input pins.
Both GOn pins, when enabled in EEPROM, serve as generic output pins. The following functions can
be accomplished with these pins.
GIn/GOn Options:
1) A negative-going edge is detected on either GIn pin. The state of both pins is transmitted over
the RF (as configured by RF Mode)
Mode and will be presented to corresponding GOn pins on the
remote radio(s).
2) A “CC” command is issued to force an update on remote radio’s GOn pins. The state of both
local GIn lines is transmitted over the RF (as configured by RF Mode)
Mode and will be presented to
corresponding Gon pins on the remote radio(s).
3) The Read Digital Inputs “CC” command is issued to read the state of both GIn pins locally
(details can be found in the On-the-Fly Control Command Reference).
4) The Write Digital Outputs “CC” command is issued to write all GOn pins locally to particular
states (details can be found in the On-the-Fly Control Command Reference).
5) A “CC” command is issued to write the GOn pins on a remote radio to particular states.
Those states are transmitted over the RF (as configured by RF Mode)
Mode and will be presented to
the corresponding pins on the remote radio(s).
5.1.2 TXD (Transmit Data) and RXD (Receive Data) (pins 2 and 3 respectively)
The AC4490 accepts 3.3 or 5VDC TTL level asynchronous serial data on the RXD pin and interprets
that data as either Command Data or Transmit Data. Data is sent from the transceiver to the OEM Host
via the TXD pin. The data must be of the format 8-N-1 (8 data bits, No Parity bits, One stop bit).
5.1.3 Hop Frame (pin 6)
The AC4490 is a frequency hopping spread spectrum radio. Frequency hopping allows the system to
hop around interference in order to provide a better wireless link. Hop Frame transitions logic Low at
the start of a hop and transitions logic High at the completion of a hop. The OEM Host is not required
to monitor Hop Frame.
2/18/03
25
AC4490 Specifications
5.1.4 CTS Handshaking (pin 7)
The AC4490 has an interface buffer size of 256 bytes. If the buffer fills up and more bytes are sent to
the transceiver before the buffer can be emptied, data corruption will occur. The transceiver prevents
this corruption by asserting CTS High as the buffer fills up and taking CTS Low as the buffer is
emptied. CTS On in conjunction with CTS On Hysteresis control the operation of CTS. CTS On
specifies the amount of bytes that must be in the buffer for CTS to be disabled (High). Even while CTS
is disabled, the OEM Host can still send data to the transceiver, but it should do so carefully. Once
CTS is disabled, it will remain disabled until the buffer is reduced to the size specified by CTS On
Hysteresis.
5.1.5 RTS Handshaking (pin 8)
With RTS Mode disabled, the transceiver will send any received packet to the OEM Host as soon as
the packet is received. However, some OEM Hosts are not able to accept data from the transceiver all
of the time. With RTS Mode Enabled, the OEM Host can keep the transceiver from sending it a packet
by disabling RTS (logic High). Once RTS is enabled (logic Low), the transceiver can send packets to
the OEM Host as they are received. Note: Leaving RTS disabled for too long can cause data loss
once the transceiver’s receive buffer fills up.
5.1.6 9600 Baud/Packet Frame (pin 12)
9600_BAUD – When pulled logic Low before applying power or resetting, the transceiver’s serial
interface is forced to a 9600, 8-N-1 (8 data bits, No parity, 1 stop bit) rate. To exit, transceiver must be
reset or power-cycled with 9600_Baud logic High.
Packet Frame – When enabled in EEPROM, Packet Frame will transition logic Low at the start of a
received RF packet and transition logic High at the completion of the packet.
5.1.7 RSSI (pin 13)
Instantaneous RSSI
Received Signal Strength Indicator is used by the Host as an indication of instantaneous signal
strength at the receiver. The Host must calibrate RSSI without a RF signal being presented to the
receiver. Calibration is accomplished by following the steps listed below to find a minimum and
maximum voltage value.
1) Power up only one Client (no Server) transceiver in the coverage area.
2) Measure the RSSI signal to obtain the minimum value with no other signal present.
3) Power up a Server. Make sure the two transceivers are in close proximity and measure
the Client’s peak RSSI once the Client reports In Range to obtain a maximum value at full
signal strength.
2/18/03

AC4490 Specifications
Validated RSSI
As RSSI values are only valid when the local radio is receiving a RF packet from a remote radio,
instantaneous RSSI can be very tricky to use. Therefore, the transceiver stores the most recent valid
RSSI value. The Host issues the Report Last Good RSSI command to request that value (details can
be found in the On-the-Fly Control Command Reference). Validated RSSI is not available at the RSSI
pin.

5.1.8 UP_Reset (pin 15)
UP_Reset provides a direct connection to the reset pin on the AC4490 microprocessor. To guarantee
a valid power-up reset, this pin should never be tied Low on power-up. For a valid power-on reset,
reset must be High for a minimum of 50us.
5.1.9 Command/Data (pin 17)
When logic High, transceiver interprets Host data as transmit data to be sent to other transceivers and
their Hosts. When logic Low, transceiver interprets Host data as command data (see section 4).

5.1.10 AD In and AD Out (pins 18 and 19 respectively)
When enabled in EEPROM, AD In and AD Out can be used as a cost savings to replace Analog-toDigital and Digital-to-Analog converter hardware. The following conditions are all possible when
enabled in EEPROM. Note: AD Out is an unbuffered, high impedance output and must be buffered by
the OEM Host when used.
1) A refresh rate can be programmed in EEPROM to cause a transceiver to read the AD In port
and send the state of that port over the RF (as configured by RF Mode)
Mode and will be presented
to the AD Out pin on the remote radio(s).
2) A “CC” command is issued to cause a transceiver to read the AD In port locally and send the
state of that port over the RF (as configured by RF Mode)
Mode and will be presented to the AD Out
pin on the remote radio(s).
3) The Read ADC command is issued to read the state of AD In locally (details can be found in
the On-the-Fly Control Command Reference).
4) The Write ADC command is issued to write the AD Out pin to a particular state locally (details
can be found in the On-the-Fly Control Command Reference).
6) A “CC” command is issued to write the AD Out pin on a remote radio(s) to a particular state.
This state is transmitted over the RF (as configured by RF Mode)
Mode and will be presented to the
AD Out pin on the remote radio(s).
5.1.11 In Range (pin 20)
The IN_RANGE pin at the connector will be driven logic Low when a Client is in range of a Server on
the same RF Channel and System ID
ID. If a Client cannot hear a Server for 7.5s, it will drive the
IN_RANGE pin logic High and enter a search mode looking for a Server. As soon as it detects a
Server, the IN_RANGE pin will be driven logic Low. A Server Host can determine which Clients are in
range by the Server’s Host software polling a Client’s Host.
5.2 SOFTWARE PARAMETERS
Below is a description of all software parameters used to control the AC4490.
5.2.1 RF Architecture (Unicast/Broadcast)
The Server controls the system timing by sending out regular beacons (transparent to the transceiver
Host) which contain system timing information. This timing information synchronizes the Client radios
to the Server.
Each network should consist of only one Server. There should never be two Servers on the same RF
Channel Number in the same coverage area, as the interference between the two Servers will severely
hinder RF communications.
The AC4490 runs a Peer-to-Peer type architecture where all transceivers, whether Servers or Clients,
can communicate with all other transceivers. To prohibit transceivers from receiving broadcast
packets, Unicast Only can be enabled.
2/18/03
28
AC4490 Specifications
5.2.2 RF Mode
All radios located on the same network must use the same RF Mode.
RF Delivery Overview
All packets are sent out over the RF as either addressed or broadcast packets. Addressed packets are
only received by the radio specified by Destination Address
Address. If addressed packets are desired, the
Destination Address should be programmed with the MAC ID of the destination radio. To simplify
EEPROM programming, Auto Destination can be enabled in Clients which allows the Client to
automatically set its Destination Address to the address of the Server. Broadcast packets are sent out
to every eligible transceiver on the network. If broadcast packets are desired, RF Delivery should be
set to Broadcast.
Acknowledge Mode
In Addressed Acknowledge Mode, the RF packet is sent out to the receiver designated by the
Destination Address
Address. Transmit Retries is used to increase the odds of successful delivery to the
intended receiver. Transparent to the OEM Host, the sending transceiver will send the RF packet to
the intended receiver. If the receiver receives the packet free of errors, it will tell the sender. If the
sender does not receive this acknowledge, it will assume the packet was never received and retry the
packet. This will go on until the packet is successfully received or the transmitter exhausts all of its
retries. The received packet will only be sent to the OEM Host if and when it is received free of errors.
In Broadcast Acknowledge Mode, the RF packet is broadcast out to all eligible receivers on the
network. In order to increase the odds of successful delivery, Broadcast Attempts is used to increase
the odds of successful delivery to the intended receiver(s). Transparent to the OEM Host, the sending
transceiver will send the RF packet to the intended receiver. If the receiver detects a packet error, it will
throw out the packet. This will go on until the packet is successfully received or the transmitter
exhausts all of its attempts. Once the receiver successfully receives the packet it will send the packet
to the OEM Host. It will throw out any duplicates caused by further Broadcast Attempts. The received
packet will only be sent to the OEM Host if it is received free of errors.
Stream Mode
In Broadcast Stream mode, the RF packet is broadcast out to all eligible receivers on the network. In
Addressed Stream Mode, the RF packet is sent out to the receiver designated by the Destination
Address.
Address The sending transceiver will send each RF packet out once. There are no retries on the
packet. Whether or not the packet contains errors, the receiver(s) will send the packet to the OEM
Host. However, if receiver is not able to receive the packet in its entirety (there are bytes missing), it will
not send the packet to the OEM Host. In order to increase the odds of successful delivery, Forward
Error Correction (FEC) may be used. FEC is used (transparent to the OEM Host) to increase the odds
of correctly receiving a packet sent over the RF. When enabled, the transceiver will send every byte
over the RF 3 times and then perform a best-of-three bit-wise decision on the received bytes. Enabling
FEC can cut overall throughput by 1/3. Note: All transceivers on the same network must have the
same setting for FEC. Stream Mode is incompatible with Full Duplex Mode.
5.2.3 Sub Hop Adjust
Sub Hop Adjust is an AC4490 protocol parameter and should only be modified at the recommendation
of Aerocomm.
2/18/03
29
AC4490 Specifications
5.2.4 Duplex Mode
In Half Duplex mode, the AC4490 will send a packet out over the RF when it can. This can cause
packets sent at the same time by a Server and a Client to collide with each other over the RF. To
prevent this, Full Duplex Mode can be enabled. This mode restricts Clients to transmitting on odd
numbered frequency “bins” and the Server to transmitting on even frequency bins. Though the RF
hardware is still technically half duplex, it makes the radio seem full duplex. This can cause overall
throughputs to be cut in half. Note: All transceivers on the same network must have the same setting
for Full Duplex. Full Duplex mode is incompatible with Stream RF mode.
5.2.5 Interface Timeout/RF Packet Size
Interface timeout, in conjunction with RF Packet Size
Size, determines when a buffer of data will be sent out
over the RF as a complete RF packet based on whichever condition occurs first.
Interface Timeout – Interface Timeout specifies a maximum byte gap in between consecutive bytes.
When that byte gap is exceeded, the bytes in the transmit buffer are sent out over the RF as a
complete packet. Interface timeout is adjustable in 1ms increments and has a tolerance of ±1ms.
Therefore, the Interface Timeout should be set to a minimum of 2. The default value for Interface
Timeout is 4 or 4ms.
RF Packet Size – When the amount of bytes in the transceiver transmit buffer equals RF Packet Size,
those bytes are sent out as a complete RF packet.
5.2.6 Serial Interface Baud Rate
This two-byte value determines the baud rate used for communicating over the serial interface to a
transceiver. Table 5 - Baud Rate/Timeout lists values for some common baud rates. Baud rates below
1200 baud are not supported. For a baud rate to be valid, the calculated baud rate must be within ±3%
of the OEM Host baud rate. If the 9600_BAUD pin (Pin 12) is pulled logic Low at reset, the baud rate
will be forced to 9,600.
9,600. For Baud Rate values other than those shown in Table 5 - Baud Rate,
Rate the
following equation can be used:
BAUD = 100h - (14.7456E+06 / (64 * desired baud rate))

5.2.7 Network Topology
RF Channel Number – RF Channel Number provides a physical separation between co-located
networks. The AC4490 is a spread spectrum frequency hopping radio with a fixed hopping sequence.
Without synchronizing the different networks to each other, different channel numbers could possibly
interfere with each other and create “cross-talk.” To avoid cross-talk interference, co-located networks
should use Sync-to-Channel.
Sync-to-Channel A Server radio with Sync-to-Channel enabled will synchronize its
frequency hop timing to a system located on the RF Channel specified by Sync Channel
Channel. The only
requirement is that Sync Channel be numerically less than RF Channel. Therefore, every co-located
network will be synchronizing to the network with the lowest RF Channel. Four Channel sets are
provided for the AC4490. Co-located networks must use the same Channel Set.
