Jumpers in RS-232 Connectors

Some software programs and some operator interface
terminals require a Clear to Send (CTS) signal in response to
their Request to Send (RTS) signal, or a Data Set Ready (DSR)
in response to their Data Terminal Ready (DTR). The PPC-
2000 is not configured to receive or transmit these signals. To
use such software with the PPC, jumper RTS to CTS and DTR
to DSR in the DB connector. Table 2.29 lists the standard pin
assignments for DB-9 and DB-25 connectors.

RTS/CTS Pins in DB-9 and DB-25
Connectors

Cables manufactured by Watlow Anafaze for RS-232
communications include these jumpers. AnaWin3 and LogicPro
do not require these jumpers and are not affected by their
presence.
