NOTE: One Intelliswitch serial cable assembly (part #
505SC***INT485-A) is required for every unit that is to
be used as a master/slave. "***" denotes length of cable
in feet- "008" = 8 feet long.
For Master/Slave operation, a serial cable connection must
be made between the INTELLISWITCH GEN2 control boards
of each unit to be linked.
1.
Disconnect power to all the units.
2.
Access the wiring tray on top of each unit by removing
the screws that hold the cover in place.
3.
Find the (RS485) phone jack couplers in the wiring
trays. There will be two short cables in the wiring
tray of each air curtain, each with a double ended
female phone jack coupler attached to the cable.
4.
The serial cable ordered for each unit will be coiled up
in the wiring tray of the unit and connected to one of
the couplers.
Note: There may be one less serial cable than the
number of units ordered. e.g. Two units together will
need only one cable; three units together will need two
cables, etc. Any extra cables can be kept as spares.
5.
Use one of the extra electrical knockouts to route serial
cable from one unit to the next. Be sure to protect the
edge of the knockout properly.
6.
Plug (RS485) male phone jack on the end of the serial
cable into the empty coupler on the next unit.
7.
Continue process for all units that are to be connected
serially.
8.
Serial cable connections are capable of two way com
munication. It does not matter which coupler the
cables are connected to.
9.
The first and last air curtains in the group will each
have an empty coupler after all connections are made.
So if there are only two air curtains connected, each
will have an empty cable coupler.
