Preparing for use Introduction Unpacking and inspection 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. Unpack the modem and check that you have received the following items: 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 fixed applications.

Description of modem Features The me-d200/d350 is a network free, point to point data radio that offers great flexibility in varied applications where wireless data or voice communication is needed. ● ● ● ● ● ● ● ● ● It can be used as a “dumb” radio, with no internal module fitted, 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.

Channel selection Serial commands 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.

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.
PAGE 13
Power sources Fixing It is important that a “clean” source of power is used for the supply to the modem We recommend that the me-d200/d350 is securely fixed to a surface, either directly, or with a suitable bracket. The fixing hole centre dimensions are as shown. Fuse replacement We recommend an inline “quick blow” fuse rating of 4 amps be fitted to the +ve supply. The modem can be attached to any surface by using suitable size screws through the M3.5 holes in the mounting flanges. Cabling 108.

Safety and general information Vehicles with airbags Important information on safe and efficient use of your Radio device Air bags inflate 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. 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.
PAGE 15
Warranty and repairs Declaration of conformity* The me-d200/d350 is a low maintenance device. Once installed it requires no ongoing maintenance. In the event that your Mobile Expertise me-d200/d350 modem needs repair, return your radio to an authorised Mobile Expertise supplier. Do not disassemble, modify or repair the unit unless the work is carried out by a Mobile Expertise approved supplier.
