Serial Communication; Figure 81 - Pc Serial Connection - Cims/Acus - Keyscan CA250 Series Technical Manual

Serial Communication

Serial communication is a direct serial connection from the PC to the CIM unit using a 9-pin RS-232 data cable
with five (5) conductors - Keyscan part # 40-2322. A Communication Manager/Service must be installed on
the PC that has the direct serial connection to CIM 0.
