Modem System
A modem system uses a standard phone line to connect the computer to the sign. At the display,
simply plug into a phone cable from the J-box into the jack labeled “PHONE IN” (the plug location
is at the same point as shown in Figure 17). Hook up the modem per the manufacturer’s
instructions, and then follow the Venus 1500 manual (ED-12717) to determine the modem’s
configuration. Refer to Drawing A-91386.
TCP/IP or LAN System
A LAN system requires a computer running on a LAN. Connect the serial server to the LAN.
The server has an RS232 output just as a PC would. Follow the steps for the setup of a RS232
system. Refer to Drawing A-93904.

The sign-to-sign connections are the same for the
RS232 system, RS422 system, modem system and
TCP/IP. Refer to the riser diagrams listed above.
When wiring a sign to sign network, the cable and
connectors discussed earlier in this section are
used. Pay special attention to the information
regarding flipped cables to help ensure a successful
installation. The best method of wiring the signs
together is to start at the first sign, as it is
designated to begin the network.
1. Plug the cable into the “SIGNAL OUT” output jack of the first sign (refer to Figure 18) and
the other end of the cable into the input jack of the next sign.
2. Continue this procedure throughout the network. When the wiring is complete, the last sign will
have nothing in the output jack.
