➉ Optical Communications Port. This port allows the circuit monitor to
communicate to a portable computer using the optional optical
communications interface (Class 3090 Type OCI-2000). The OCI-2000
mounts magnetically to the circuit monitor and provides a standard
RS-232 interface. Anything that can be done over the RS-485
communications link—including circuit monitor setup—can also be done
using the optical communications port.
