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.
