Introduction
The me-d200/d350 range is a 1 to 5 Watt radio data
modem, which can be used for data up to 9600 baud rate
(using GMSK module) in stand alone conditions.
The me-d200/d350 is housed in a rugged cast-aluminium
box sealed to IEC 529 (IP54) making it suitable for a wide
range of mobile and xed applications.
All me-d200 modem units meet the essential requirements
of the relevant European directives and all me-d350
modems meet relevant US FCC and Canadian regulations.
In order to maintain this compliance the installation and
safety information must be adhered to at all times.
The me-d200/d350 modem must only be installed where
unintentional contact cannot be made. The surface of
the device may be hot to touch under certain transmit
conditions. A warning label is permanently displayed as
part of the equipment rating label af xed to the lid. The
me-d200/d350 is not designed for permanent transmis-
sion. If prolonged transmission periods are used, the
unit will become hot and will require an additional
heatsink to be tted.
When tting the me-d200/d350 into a xed installation,
care must be taken in the routing of all cabling such that
the insulation cannot become damaged.
The recommended supply sources for use with the me-
d200/d350 are a standard 12V supply, but is capable of
operating in the range
(9V - 18V).

Description of modem
The me-d200/d350 is a network free, point to point data
radio that offers great exibility in varied applications where
wireless data or voice communication is needed.
It can be used as a “dumb” radio, with no internal module
tted, to allow users to facilitate the use of their own
modem and protocol. Internal link changes enable the input
to be set for TTL levels so allowing POCSAG for example.
In this scenario, the radio is completely transparent and
simply needs the correct signal level inputs (see pin out
details), and use of separate control lines (PTT etc) or
serial commands.
The me-d200/d350 can also be tted with either a Bell
202,V.23 module, a FFSK module (up to 4800 baud rate)
or a GMSK module (up to 9600 baud rate). These allow
communication with a pc via hyper terminal and other
emulation packages. For further information on these
options, including pin outs, please refer to the separate
Module Manual available on the Mobile Expertise web site.
The me-d200/d350 also operates as a standard radio with
microphone input and speaker output, in this mode the
radio has the following associated features, these include
CTCSS/DCS, busy channel lockout and scan

Channel selection
Channels are selected by the use of internal switches and
can be set as shown below. The bottom 4 screws will
need to be removed to gain access to the switches, care
must be taken to avoid any damage which could invalidate
the warranty.The channel can also be changed by a serial
command inputted from the external control system.
Figure: Setting of channel selector switch for each channel
By altering link options, channel change can also be
implemented using TTL levels on pins 11,12,13 & 15 of
DB15 way assuming these pins are not in use and default
conditions are met. Refer to Application Notes on the
Mobile Expertise web site.
Operation
Transmit/receive operation
The me-d200/d350 can be put into transmit by different
methods. When used as a “dumb” radio, the PTT line is
pulled low (pin 3 of DB15). The Tx serial command will
also put the radio into transmit (pin 8 of DB15), until the Rx
serial command is received.
Where an internal module is tted the PTT/Busy links are
changed to RS232 (see module manual). The GMSK and
FFSK can in addition operate automatically by going into
“TX” on receipt of data on pin 10 of DB15.
Serial commands
The modem can be controlled by using the serial command
(pin 8) data in, sending commands to the radio such as
PTT or change channel
The format for these commands (asynchronous) are:
Baud rate: 4800 bit/sec
Data: 8 bit,
Parity: Non parity
Stop Bit (SP): 1 bit
MSB rst transmission
Each serial command consists of 3 bytes. The rst byte is
the command (CMD), the second is data (DATA) required
by the command and the third is the check sum (CS) to
validate contents
TX Command format:
CMD DATA CS
1st byte 2nd byte 3rd byte
N.B. Check Sum = 1st byte + 2nd byte. CS = CMD + DATA
Response format:
CMD DATA1 DATA2 ... DATAn
The response CMD is in the form of:
ACK, acknowledge, Hex: 0xAA; (then data if any)
NACK, no acknowledge (error in command) Hex: 0x55
NOK, not okay (cannot carry out command) Hex: 0x65
If command is not recognised, repeated or already in
requested or wrong state e.g channel change in TX there is
no response from the radio.

IStandard radio commands
Scanning
A scan function is available whereby any or all 16 channels
can be monitored for activity. Scanning parameters such
as scan speed and delay are programmable (refer to
programming guide)
Control of the scan channels is by serial commands.
Note The priority channel (the transmit channel during
scanning) is the channel selected via the dip switch.
Timings
Radio timings parameters are available for alteration via the
programmer.
These include:
Time-out timer,
Hang timer -transmit after dis-asserting PTT
Tx delay - prevents squelch noise when using CTCSS/
DCS
Busy Channel Lockout
Prevents TX when while the radio is receiving. Refer to
programming guide more more detail.
N.B. Where the module option board is tted alternative
programmable functions apply.

Internal Module Timings
Tx delay and Rx delay timings are available for alteration
when the internal module is tted only. Please refer to the
programming guide and module manual for details
Power Save Mode
The modem will go into power save mode for short periods
of time to minimise power consumption when a battery
supply is being used. Parameters are programmable.
Enhanced Power Save Mode (sleep)
The modem in this mode deactivates all circuitry with
the exception of the micro controller. It is activated and
deactivated using serial commands (see Command List).
Current consumption is signi cantly reduced to
approximately 7mA and represents an 85% saving on
normal standby consumption.
Squelch
The modem offers 2 forms of squelch, which are
programmable as RSSI level check or busy port .
RSSI level uses the RSSI level from the FM detector
chip and the point of squelch is programmable.
Noise saquelch uses the ‘on board’ circuitry to detect
noise and is manually adjusted.
Status indicators and Audible alerts
The LED indicates the current status of the radio and if
an external speaker is connected to pin 9 of the DB-15,
audible tones can be heard under certain fault conditions.

per channel basis
Radio settings such as power save mode,Tx lockout, Tx
timeout, Squelch
Module options when FSK, FFSK and GMSK module
is tted, such as setting baud rate, dumb or auto mode,
Hyper Terminal mode and data settings ( ow control,
block size etc)
The pc program also allows for squelch adjustments and
calibration Refer to programming manual and PC software.
Installation
Antennas
It is important that any antennas are installed in a suitable
location with an adequate ground plane. Ideally, multiple
antennas should be separated by a minimum of a
wavelength (at the lowest frequency), whilst still retaining
a good ground plane for each antenna. Therefore, for a
400MHz system, the ideal separation should be a minimum
of 0.75m (~30in), and for 150MHz system the minimum
should be 2.5m (~98in).
Warning: If installing an antenna near people it is necessary
to ensure the minimum separation is maintained. This
particularly important where prolonged exposure is likely.
For a full range of antenna options and other accessories
visit the Mobile Expertise web site.
24 25
Power sources
It is important that a “clean” source of power is used for the
supply to the modem
Fuse replacement
We recommend an inline “quick blow” fuse rating of 4 amps
be tted to the +ve supply.
Cabling
If possible, run RF cables separately from other cables
and keep RF cables apart from one another to avoid
interference / coupling.
When tting the modem into a xed installation care must
be taken in the routing of all cabling such that the insulation
cannot become damaged.
Fixing
We recommend that the me-d200/d350 is securely xed
to a surface, either directly, or with a suitable bracket. The
xing hole centre dimensions are as shown.
The modem can be attached to any surface by using
suitable size screws through the M3.5 holes in the
mounting anges.

Safety and general information
Important information on safe and ef cient use of your
Radio device
Exposure to radio frequency energy
Your modem is a high power radio transceiver. When
it is on, it receives and also sends out radio frequency
(RF) signals. To help minimise human exposure to RF
electromagnetic energy, keep transmission time to 50%
or less.
As with all radio devices, holding the antenna affects
transmission quality and may cause the radio to operate at
a higher power level than required. Do not hold the antenna
when the radio is in use.
Do not use radios with damaged or modi ed antenna,
this may violate compliance with relevant international
standards.
Where prolonged human exposure is likely, the minimum
separation from the antenna should be 0.8m.
Electromagnetic
interference/compatibility
Most modern electronic equipment is shielded from RF
energy. However certain electronic equipment may not
be shielded against RF signals. The modem needs to be
switched off in any facility where posted notices instruct
you to do so to avoid electromagnetic interference or
compatibility con icts. Special care should be taken near
facilities such as hospitals or health care centres may be
using equipment that is sensitive to external RF energy.
Medical devices (Pacemakers)
If you use any personal medical device, consult the
manufacturer of your device to determine it is adequately
shielded from RF energy. Your physician may be able to
assist you in obtaining this information.
Vehicles with airbags
Air bags in ate with great force. Do not place a radio in the
area over an airbag or in the airbag deployment area, any
radio may be propelled with great force and cause serious
injury to the occupant of the vehicle.
Potentially explosive atmospheres
Turn off your modem prior to entering any area with a
potentially explosive atmosphere, unless it is a radio
type especially quali ed for use in such areas. Do not
remove install or charge batteries in such areas. Sparks in
potentially explosive atmospheres can cause an explosion
or re resulting in bodily injury or death.
Potentially explosive atmospheres include fuelling areas
such as petrol stations, below decks on boats, fuel or
chemical transfer or storage facilities, vehicles using liquid
petroleum gas (such as propane or butane); areas where
the air contains chemicals or particles such as grain, dust
or metal powders, and any other area where you would
normally be advised to turn off your vehicle engine. Areas
with potentially explosive atmospheres are often but not
always posted.
