Chapter 2 - Installation
Cabling your MultiFRAD
Cabling your MultiFRAD involves making the proper Power, Command Port, Ethernet, and Channel
connections. Figure 2-2 shows the back panel connectors and the associated cable connections.
Table 2-1 details the procedures for connecting the cables to your MultiFRAD.
Table 2-1. Cabling Procedure
Step Procedure
1 Connect one end of a (supplied) DB25 back-to-back cable to each of the data channel
connectors on the back of your MultiFRAD (labeled CHANNEL 1-2). See Figure 2-2. Connect
the other end of each cable to a channel device.
NOTE: Both channels support the RS232/V.35 protocols, and either asynchronous or HDLC
synchronous RS232 data equipment such as multiplexers.

2 Connect one end of an DB25 (female) cable to the Trunk connector (Figure 2-2). Connect the
other cable end to your T1 CSU/DSU or compatible link device.
3 To make the network connection, connect an RJ-45 (UTP) cable to the 10 BASE-T Ethernet
connector or the male connector for a 10Base5 cable to the AUI Ethernet connector (shown
in Figure 2-2). Connect the other end of the cable to your LAN.
4 Connect the MultiFRAD to your PC with a standard RS232 cable. Plug the male end of the
cable into the Command Port (Figure 2-2) and the other end into the PC’s serial port.
5 Connect one end of the power supply to a live AC outlet, then connect the other end to the
MultiFRAD as shown in Figure 2-2. The Power connector is a 7-pin circular DIN connector.
6 Apply power to the MultiFRAD by setting the Power switch (Figure 2-2) to the “1” (on)
position.
At this time your MultiFRAD is completely cabled. Proceed to the next section to install your software.
