The L2 submodule provides compatible signals for a DSC-1000 L2 Bus
(C210 and C260 controllers). The L2 submodule inserts in only
one orientation. There is one switch to set on the L2 submodule:
Channel A/B Switch: Indicates which terminal blocks the L2 connects to
on the communication panel. Set to Channel B, corresponding with the
TB2 terminals on the TBC.
For applications requiring a second N2 Bus, use the N2 submodule, which
provides compatible signals for N2 devices. For complete information,
see the Dual N2 Bus Application Note (LIT-6363145) in this manual.
The N2 submodule inserts in only one orientation. There are two switches
to set on the N2 submodule:
Channel A/B Switch: Indicates which terminal blocks the N2 connects to
on the communication panel. Set to Channel B, corresponding to the TB2
terminals on the TBC.
End-of-Line (EOL) Switch: Indicates whether the NCM is one of the
two EOL devices on the N2 bus. Setting the N2 EOL to In means the
NCM is EOL. Out means that other modules are daisy-chained (in the
backplane) both upline and downline of the NCM.
The RS-232 submodule provides input/output at standard RS-232C levels.
The RS-232 submodule inserts in only one orientation.
There are no switches to set. However, because of the recessed connector
on the NCM, a special right-angle cable with a narrow profile shell is
required to attach to the RS-232 submodule. One end of this cable
(NU-CBL101-0) arrives pigtailed.
