1. Verify printer has serial capability. Printers use 25-pin D connectors for serial
communications and 36-pin ribbon connectors for parallel communications. Some
printer manufacturers offer serial printers as an option only.
2. Verify printer is on and Select light or On Line light is ON.
3. Verify that the cable is wired with the pin assignments shown above.
4. Verify that interface cable is plugged into PRINTER connector and not the TERMINAL
port on the Model 512.
5. Turn power off and then on after making switch changes on the printer. This causes the
printer to read the new switch settings.
6. Verify in the printer manual that pin 11 is used by the printer to control data and the
polarity is correct.
7. If tester stays in the printing mode, the polarity of SSD could be incorrect. Disconnect
pin 11 and verify printing.
8. If data is printed at random but most of the data is correct, the data control signal into pin
11 of the tester is incorrect. Refer to printer manual.
9. Verify that both the printer and the tester baud rates are set to 1200.
