SOI Up/Download via RS-232 Communication Port with SCC-3 Cable
If you don’t want to build your own cable, Spectrum Controls offers the
SCC-3 cable for uploading/downloading application programs. The
following illustrations describe the SCC-3 cable. Use the SCC-3 cable
to connect the RS-232 communication port of the SOI to a personal
computer for transferring application programs. A 9-to-25 pin adapter
may be required if your computer has a 9-pin communication port.
