MAXICOM INTERFACE SITE
BOARD
Central Controller Connection
There are two ways of connecting the ESP-LX PLUS SITE
to the computer data path:
the phone or serial port
(RS232).
•
Phone:
Connect one side of a RJ-11 telephone cable
into J4 (1a) and the other end to an RJ-11 telephone
jack (or cellular phone interface, if applicable). Set
switch S2 to the “PHONE” position. This is the factory
default setting. Run the telephone cable from the MISB
Cabinet using the knockout for a PVC male adapter
sized
3
⁄
4
" (1,9 cm) on the right hand side of the cabinet.
This same hole will be used to run sensor wires to the
MISB. Conduit is recommended for both phone and
sensor cables/wires.”
•
Serial Port (RS-232):
Connect the “cable assembly,
modem-site” into the DB-9 Connector and the opposite
end to the modem. Set S2 to “RS-232” position.
Important:
Do not set switch S2 in the center
position; it must always be set fully left or right.
If your controller is connected directly to the computer, or
if you are using a short-haul modem (point to point), set
the S1 switch to the DCE position.
If your communication line is connected to one of the non-
hardwire or multi-drop short-haul modem options set the
S1 switch to the DTE position.
Verify that the black, two-pronged W1 jumper is inserted
in the “DSR” position. The W1 jumper in the “CTS” posi-
tion is only necessary for trunk radio communication.
