Modem

In a display that uses a modem, Signal In routes first to a telecommunications
connector and terminated per the table below. A 6-conductor phone cord with RJ11
connectors (part number 0A-1137-0160) relays the signal to the modem. A second
phone cord (0A-1137-0160) transfers the data from the modem to J1 (RS232 IN) on
the controller.

Fiber Optic

When the fiber optic cables are used, signal from the converter enters the fiber board
(J4/J5). An adapter module (Daktronics part number 0A-1146-0029) allows the use
of a 6-conudctor-phone cord with RJ11 connectors (par number 0A-1137-0160) to
relay the signal to J1 (RS232 IN) on the controller.
