See Figure 8A or the manufacturer's documentation for

COM port connector pin-out details. Interconnect the
control data connections between the PC and the
appropriate CEC/IMC Data Concentrator Card as required.
Shielded pairs are recommended.

Remote Console Interconnections Via A 4-Wire Modem

When the C3 Maestro is installed at a remote location

from the CEC/IMC, serial control data must be routed via
RS-232 connections and 4-wire modems. Since the C3
Maestro requires a dedicated or continuous serial link (non-
dial-up), a 4-wire leased line (or equivalent) meeting 3002
data grade specifications must be employed between the
CEC/IMC and the C3 Maestro in a remote console
installation.

Figure 8B shows typical control data interconnections

for a remote console installation using RS-232 connections
and full-duplex 4-wire modems. At the CEC/IMC Data
Concentrator Card, RS-232 connections are made at J13,
not J12. Observe all notes listed in the figure if wiring an
installation of this type
. Recommended modem settings
are:
