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.
