Using a Peripheral Communication Module
Appendix A
AĆ7
In configuring your PLC-3 system, both the 1775-S4B scanner and the
peripheral communication module use the CRT defaults selection for
RS-232-C communication. This selection configures:
Channel 5 on the 1775-S4B scanner for report generation protocol.
RS-232-C channels on the peripheral communication module for GA
Basic protocol.
One parameter that the CRT defaults selection sets is the form feed. The
form feed parameter determines what character or characters are
transmitted by the channel to accomplish the form feed function. Your
selections are:
Not Expanded—The channel sends a FF (form feed) character.
Expanded—The channel sends seven LF (line feed) characters.
When you select CRT defaults for:
Channel 5 on the 1775-S4B scanner, the form feed parameter is set for
expanded.
RS-232-C channels on the peripheral communication module, the form
feed parameter is set for not expanded.
