"Looking at the back or the wiring side"

Motorola CDM series: [you can use a 16 or 20 pin plug]
16 Pin plug fits into the 20 pin accessory connector as seen in red above

Note: Wire above you will NOT need to use the external 2.1 mm connection.

Jumper Option: The Motorola can provide power through its accessory connector to the DB9 when wiring as shown in the above diagram
TNC Jumpers will need to be set as  listed below.

If you do not have access to a service monitor then set command - XMITL 268
XMITL is a approx. hen setting for Motorola Maxtrac/M series and CDM's

Changing either the Radio or TNC, the XMITL will need to be matched for 2.75 Khz deviation.

Our testing showed 25% better throughput was acheived when the XMIL is set correctly in our area that has Ocean and Mountains

Note: Motorola's has programable accessory pins if your are wiring for other uses
