Examples of RS232 communications could involve another Red Lion
product or a PC. By using a cable with RJ12 ends on it, and a twist in the cable,
RS232 communications with another G3 product or the Modular Controller can
be established. Red Lion part numbers for cables with a twist in them are
CBLPROG0
