LBI-39055
FDX Jumper
SLOT 8 Jumper
-BIAS and +BIAS
Configuration for the 3PXOCC1A board is:
Address Switches (S1)
Interrupt Jumper
Jumpers JP12 − JP15
Jumpers JP16 − JP17
If any other RS-422 plug-in serial board is used the
following board configuration must be used:
COM Port
Port Address
Interrupt
See Figure 8A or the manufacturer's documentation for
COM port connector pin-out details. As required,
interconnect the control data connections between the PC
and the appropriate CEC/IMC Data Concentrator Card or
the
respective
punch
recommended.
In some cases, the console equipment package is
equipped with a factory pre-wired 100-foot control data
cable. This cable has a female DB-25 connector on one end
for mating to the RS-422 plug-in serial board's male DB-25
connector. The other end is "pig-tailed" (unterminated) so
the wires may be punched down to the appropriate terminals
on the CEC's/IMC's punch block. If utilizing the pre-wired
cable, see the Cable Assembly Diagram near the end of this
manual for wire color coding.
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:
