8 Control Modules—Network Control Module 200 Series
The Communications Submodule slot (8) allows installation of one of the
following submodules to provide different communications options:
•
the L2 submodule, to integrate a C210 or C260 controller to Metasys
•
the N2 submodule for connection to a second N2 Bus to integrate N2
devices. See the Dual N2 Bus Application Note (LIT-6363145) for
details.
•
an internal modem submodule, to connect to remote operator devices
such as a printer or OWS
•
an RS-232C submodule, connecting to a printer, external modem,
S2 Migration Trunk, JC/85 Trunk, Operator Terminal, or directly
connected OWS
The RS-232C submodule is also the means by which you connect
Metasys to a host system in the Network Port application. Refer to
the Network Port Technical Bulletin (LIT-6295050) in the Metasys
Connectivity Technical Manual (FAN 629.5).
RS-232 Submodule: S2 Migration
S2 communications are made via an RS-232 submodule on the NCM200
to a Table Top Modem (TTM). The TTM then interfaces with the JC/85
trunk.
•
The S2 parameters are identical to those of the JC/85 trunks.
•
S2 Migration connections from the submodule to other devices on the
N1 LAN are identical to those of a Standard Functionality NCM200.
•
The S2 Migration NCM does not accept a second submodule for a
local L2 Bus, or other devices via the integrated N2 Bus.
•
For S2 Migration applications that require a dial-up port, you must
use the NCM401 instead of the NCM200.
RS-232 Submodule: Gateway to JC/85
The RS-232 connection on the JC/85 headend connects directly into the
RS-232 submodule on the Gateway NCM.
•
The Metasys objects on Gateway are connected from throughout the
Metasys Network via the N1 LAN in the same manner as a Standard
Functionality NCM200.
•
The Gateway NCM does not accept a second submodule for a local
L2 Bus, or other devices, via the integrated N2 Bus.
