Figure 2-6 Link via Modem

Two handshake control lines are provided on the I/O Plexer Repeater for interfacing to
modems. They are request to send (RTS) and Clear to send (CTS). 

An active high RTS signal from the I/O Plexer Repeater advises the modem that data is
available. When the modem is ready to accept data, it places its CTS line active high to the
I/O Plexer Repeater thus initiating the data exchange. 

In addition to the modem to I/O Plexer Repeater wiring the installer should confirm that JP3
(RTS/CTS Jumper) is positioned as shown in figure 2-10. Jumper JP5 (RTS/CTS for the local
RS-232 port), should remain in the horizontal position unless the RTS/CTS pair is needed in
the device connected to the local RS-232 port. A cable for most modem applications, the IOP-
RT cable, is available from duTec. 

The switches marked “Pull up” in figure 3-1 should be left in the “on” position.
