6.0  Getting Starte 
The standard MDT-A kit includes the following items: 
  MDT-A transmitter unit 
  MDT-A full breakout cable (GMS p/n 780-C0224) 
 (Power, A/V, Data, Control interfaces) 
NOTE: Based on customer application GMS may deliver additional cables and antennas. Contact GMS 
for further information. 
The MDT-A is pre-configured by GMS prior to shipment (based on customer requirements), thus is 
ready to work “right out of the box”. 
6.1  Initial Checkout 
Prior to installing a MDT-A unit into the desired target environment, an initial checkout should be 
performed to ensure proper operation of the unit. The initial checkout consists of configuring a 
basic MDL (Messenger Digital Link). 
Figure 9 shows a basic interconnection configuration to establish a wireless MDL (NOTE: 
Receivers, down converters (D/C) units and their associated hardware are sold separately). As 
mentioned in section 4.0 the MDT-A may be shipped as a stand-alone unit or mounted in an Inline 
Camera Mount box. MDT-A stand-alone units require the use of GMS’ breakout cable to provide 
power and the necessary interfacing to communicate to the transmitter. The Inline Camera Mount 
boxes require a +12 battery and most of the necessary communications can be done through the 
LCD front panel. The steps necessary to set up the configuration shown in Figure 9 are shown 
below; the differences between the Inline Camera Mount box and stand-alone unit are noted 
where applicable.
