6-1 Addition of LM unit
A basic system using the EX-200 exchange is comprised of 8
stations (2 LM units). The LM unit needs to be added according to
the following procedures when more stations are required.
(1) Establishment of the LM unit number
Set switches SW-1 and SW-2 on the LM unit to positions as
shown in the table at right according to the station numbers
connected to each LM unit. Since the LM units of a basic system
are pre-set as No. 1 and No. 2 when supplied from the factory,
the LM number has to be fixed only for the additional units.
(2) Mounting LM unit
(For the system with up to 16 stations)
Insert the additional LM units into the exchange and connect
CN1 of the LM unit to the LM unit connection cable.
(More than 16 stations)
After connecting between the EX-200 and the FC-210 with the
YR-820, mount the LM units. An earth wire of the YR-820 is to be
connected to the earth terminal of the FC-210.
