Setting the MDC ID

As previously mentioned, in most systems, it is necessary to set a unique ID for each MDC

that is installed. (NOTE: For an EDACS Data Network the MDC ID must be the same

as the LID ID of the mobile radio it is connected to. When the MDC is being installed for

use on a data network such as CDPD or Mobitex, the external modem has a unique ID

and the MDC ID may require a different type of configuration. For these systems, please

refer to the appropriate applications note for the necessary set-up parameters.)

From the MDC maintenance menu, select the MDC configuration screens by pressing the

function key next to the MDC CONFIG text. From the MDC configuration screen, press

the MDC ID function key, enter the MDC ID at the prompt and press ENTER. Press

Testing the Communications

As a final test, a message can be sent by the MDC to the receiving device, if one is

available. If an acknowledgement is received by the MDC, then it can be assumed that the

message made it to the receiving device, and the MDC is operating properly.

When the MDC is powered on, it usually defaults to some sort of sign-on screen. This

screen will usually have a function key labeled SIGNON. This key can be used to test

communications.
