CHAPTER 2: TECHNICAL INFORMATION
FRONT PANEL RJ45 CONNECTOR 
JACKS
Daniels MT-4R and MT-4D 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 MT-4R and MT-4D 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.
