LEGRAND Wattstopper LMDI-100-U Instructions D'installation page 2

Attach the LMRJ Cable
The DLM local network uses free topology low voltage wiring. The LMDI-100 can connect anywhere on the DLM local network.
CAUTION: TO CONNECT A COMPUTER
TO THE DLM LOCAL NETWORK USE THE
LMCI-100. NEVER CONNECT THE DLM
LOCAL NETWORK TO AN ETHERNET
PORT – IT MAY DAMAGE COMPUTERS AND
OTHER CONNECTED EQUIPMENT.

Upon initial power up, the LMDI-100 requires about 15 seconds of warm-up time.
During this time the unit will turn ON the top LED marked as Not Used. It will then
enable its RS-232 port with the last assigned parameters, and engage each of its LEDs
according to current network status.
The default COM parameters at power up are 19200 baud, 8 bits, no parity, 1 stop bit,
commonly written as "19200- 8-N-1".
DCE DEVICE
CONNECTION
RxD
Rx: A green LED that blinks when a message has been received from a 3rd party
TxD
controller at a rate of no more than twice per second.
GND
Tx: A green LED that blinks at a rate of twice per second when a message has been
RTS
sent to a 3rd party controller twice per second.
CTS
Config: A red LED that blinks while the system is in PnL. Sets the baud rate back
DSR
to factory default (19200 bps) for servicing when the Config button is pressed for 10
DCD
seconds.
