CHAPTER 2: TECHNICAL INFORMATION
FRONT PANEL RJ45 CONNECTOR
JACKS
Daniels P25 Radio Equipment uses RJ45 jacks on the Receiver,
Transmitter and controller cards. These jacks have several different
uses, depending on the model series and confi guration of the
equipment. The receivers and transmitters each have two separate
jacks that are connected in parallel to signal lines inside of the module.
The jacks are labeled A and B and are identical.
On the MT-4R and MT-4D Repeater modules, the jacks are used
to connect the Receiver to the controller and the controller to the
Transmitter through RJ45 interconnection cables. The interconnection
cables carry Low Voltage Differential Signaling (LVDS) serial data
as well as analog and digital COR and PTT signals. The RJ45
interconnection cables are specifi c to Daniels Electronics equipment.
Do not use Ethernet or other manufacturers cables.
On the MT-4D Base modules, the jacks are used to connect to a
Motorola® KVL3000 or KVL3000 PLUS key loader, to load encryption
keys in the Receiver and Transmitter encryption modules. This
connection uses a custom Daniels cable from the key loader to our
radio.
On all Receiver and Transmitter modules, the RJ45 jacks are also
used to connect the Daniels RSS programming software. Daniels
custom Radio Programming Interface Module (RPIM) allows the serial
port of a computer to communicate with the receiver or transmitter for
RSS programming.
