Please check this troubleshooting guide before calling BayTech Tech Support.
NOTE: This troubleshooting guide is geared towards the IBM PC family and compatibles. The term "PC" as used below refers to any IBM PC, AT, XT or compatible.
PROBLEM: DATA DOES NOT PRINT
SYMPTOM: NO PORT LEDs ILLUMINATE
CAUSE: PC serial cable or COM port.
SOLUTIONS:
1)Check cabling between PC and Print Master.
2)Check handshaking lines using TERM program. All lines (except DCD which is not used) should be high. If lines are high, turn Print Master off. You should notice CTS and DSR lines go low. If they do not go low, there is a good chance cable is incorrect (see Appendix A). Typing characters from TERM should illuminate PC LED on Print Master.
3)Check installation procedures for PC's serial port. COM1 must generate an interrupt on IRQ4 (COM2 on IRQ3). Also, check any jumpers for defining port configuration which should be jumpered for DTE, not DCE.
CAUSE: PC parallel cable.
SOLUTION: Check cable's continuity and pin configuration.
