6.3USING 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 Specifications if necessary.
4.If after sending your job to the printer, it only “beeps” indicating a “framing error” message, you may have a configuration problem. There may be some incon- sistencies 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 set- tings 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.
