The SC90 (pn 4517) was a troubleshooting tool that has been retired. This 9-pin serial line monitor provided an LED that illuminated when data was transferring between a data logger and an SM192 or SM716 data storage module. The SC90 plugged into one of the available connectors on the SC12 cable (see illustration).
