ASYNC/SYNC FIBER OPTIC MODEM
4. Installation
The Async/Sync Fiber Optic Modem is easy to install. After configuring the DIP
switches, simply connect the two fiber cables and then connect the RS-232
interface. Figure 4-1 shows the location of the fiber connections on the rear panel.

4.1 Fiber Connections
The Async/Sync Fiber Optic Modems are designed to work in pairs. You will need
one at each end of a dual-fiber cable. This cable connects to each modem using
either an ST or an SMA connector. Figure 4-2 shows a close-up of each of the
connectors.

4.2 RS-232 Connection
Because the Async/Sync Fiber Optic Modem is designed to act as either a DCE or a
DTE device, it does not need special cables to operate. Always use a straight-
through RS-232 cable.
