Installing the LMX
Configure the NT5D65 LMX DIP switches for the appropriate card address
(see
3 (SW3) is reserved and all positions should be OFF.
CAUTION
For proper operation of the Mini-Carrier
equipment, the following settings should be
verified:
•
•
•
•
Unused carrier links should be configured as "unequipped"
(using the set configuration command from the Man Machine
interface terminal), to avoid a constant alarm condition. The
alarm relay contacts will remain active during such an alarm
condition.
Install the local MMI terminal and T1 carrier link cables to the
LMI Multi I/O cable assembly. See
single Local Mini-carrier Interface card (LMI)" (page 41)
illustration of the cable connections necessary for a single LMI
system. For an illustration of the cable connections necessary to
daisy chain the LMI's terminal connection, see
Local Mini-carrier Interface cards (LMIs) in a daisy chain" (page
42).
a For single-LMI systems, SW2 positions 7 and 8 are OFF. See
Table 9 "LMI SW2 at U23 functions" (page
b For daisy-chained systems, the LMI connected to the terminal
should have SW2 position 7 OFF and SW2 position 8 ON.
The LMI connected to the SDI port should have SW2 position
8 OFF and SW2 position 7 ON. The LMIs in the middle of
the daisy chain, those not on the MMI end or the SDI end,
should have SW2, positions 7 and 8 ON. See
SDI end" (page 56)
(page 57) for brief instructions on how to properly set DIP
switches for daisy chaining.
