S
↔
P (SERIAL
↔
PARALLEL) CONVERTER (128K)
Set DIP switch position 8 to ON (parallel to serial conversion) on the S
↔
P
Converter connected to the input (transmitting) device and to OFF (serial
to parallel conversion) on the Converter connected to the output (receiving)
device. Set switch position 6 to ON for self-test mode on the output-side
Converter and to OFF for normal operation on the input-side unit (setting
both to ON at the same time might yield misleading self-test results).
6. Test your setup. Make sure the output device is plugged in and
turned on, then plug in the output-side Converter. It will perform a
diagnostic self-test and send the results to the output device. Data sent
includes the name of the Converter, the settings of its switches, and
verification of a proper cable link with its output port. After this point the
unit performs a continuous “barber pole” test, which you can watch as it
scrolls on your output device’s printout or screen. If something seems to be
wrong, see
Chapter 5: Troubleshooting
. If you’re satisfied that the output
side of the system is working properly, go to Step 7.
7. Unplug both Converters, reverse the settings of switch position 6 on
both units, replug the output-side Converter and then the input-side one.
Observe the input-side unit’s self-test. If something doesn’t seem right, see
Chapter 5
. Otherwise, go to Step 8.
8. Reset the input-side Converter. Either (1) unplug it, set DIP-switch
position 6 to OFF, and plug it back in, or (2) set position 6 to OFF while it’s
still plugged in and then hit the reset button.
9. Make sure the input device is plugged in and turned on. Your S÷P
Converter (128K) system is now ready for continuous operation.
