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 printer?
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 printer to print. But we
recommend that you eventually use a cable built to specifications as described in Sec-
tion 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 Specifica-
tions” if necessary.
4. If after sending your job to the printer, it only “beeps” indicating a “framing error” mes-
sage, 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 computer. If you
are confused as to what the printer’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.
