Using The Rs232C (Serial) Interface - SATO S8400 Operator's Manual

6.3 USING THE RS232C (SERIAL) INTERFACE

1. Is the RS232C Serial cable connected securely to
your serial port on the PC (DB- 25S Male) and to
the RS232C connector on the print engine?
2. Is the cable defective? At the very least, you should
be using a "Null Modem Cable," which crosses pins
in a specific manner. This should enable your print
engine to print. But we recommend that you eventu-
ally use a cable built to specifications as described
in Section 5: Interface Specifications
3. Check for obvious errors in the data stream.
Remember that all print jobs for serial data must be
framed by an STX and ETX. Again, see the Section
5: Interface Specifications if necessary.
4. If after sending your job to the print engine, it only
"beeps" indicating a "framing error" message, you
may have a configuration problem. There may be
some inconsistencies with the Baud Rate, Parity,
Data Bits, or Stop Bits in relation to your host com-
puter. If you are confused as to what the print
engine's current RS232 settings are, you may
choose the SATO defaults (all DIP switches in the
OFF position) to achieve 9600 baud, no parity, 8
data bits, and 1 stop bit.
