I. Modem (Modem, RS-485, RS-232)
The Modem module is an optional accessory that can be ordered with the MC-5c. It includes
a modem, RS-485 connection and RS-232 connection. The modem module connects to a
dedicated telephone line allowing remote data access directly to the device. Users can
download data or troubleshoot the system from any remote computer system.
II. RS-485
The Data Link External Communications or RS-485 module allows multiple Quadlogic meters
to be connected together in cases where PLC is not being utilized. RS-485 utilizes two (2)
shielded, twisted pairs of #16 AWG stranded wires.

IV. Abacus Electrics Optical Probe
The Abacus Electrics optical probes (Model F6Z) are bi-directional interface devices utilizing
infra-red light. By connecting to the serial port of a computer or hand-held terminal, they
permit galvanically isolated communication with the MC-5c.
Figure 3-3. The Abacus Optical Probe.
Probes are available for use with laptop or desktop computers, as well as with many of the
hand-held computers commonly used for field data collection. The probes are fitted with a
standard 9-pin 'D' connector. The optical probe is convenient to use, as no battery or power
supply connection is needed.
