Jumpers in EIA/TIA-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 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
connector. Table 2.11 lists the standard pin assignments for DB-9 and DB-25 connectors.
