EIA/TIA-232 Connections
Jumpers in EIA/TIA-232 Connectors
Some software programs and some operator interface ter-
minals 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 CLS200 is not configured to receive or transmit these
signals. To use such software with the CLS200, jumper the
RTS to the CTS and the DTR to the DSR in the DB connec-
tor. Table 2.9 lists the standard pin assignments for DB-9
and DB-25 connectors.

Connectors
Cables manufactured by Watlow Anafaze for EIA/TIA-232
communications include these jumpers. Neither AnaWin
nor Anasoft software requires these jumpers.
