Power
POWER INPUT
Connect the IEC connector end of the supplied AC cord
to the receptacle on the rear of the 788. Connect the AC
connector end of the supplied AC cord to an AC power
source that is of the correct voltage and frequency (100-240
VAC, 50-60 Hz). Use only the power cord and connector
specified for the product and your operating locale.
When the 788 is powered up correctly, the POWER LED on
the front of the unit will be lit solid green.
External Control
EXT CTRL 1 — 4
Using standard shielded twisted pair terminated with a
Phoenix connector on one end, you may connect up to two
contact closures or one potentiometer to each EXTERNAL
CONTROL input. Configuration of the EXTERNAL CONTROL
inputs is done with the External Control Wizard. These ports
may also be used to integrate with an alarm or emergency
system.
Ethernet
RJ45 Connector
Using a standard straight-through CAT5 cable terminated
with RJ45 connectors, connect the 788’s ETHERNET port
to either your computer’s Ethernet port or to an existing
Ethernet network. You may wish to review the Network
Configuration section for more information.
When the 788 has a physical network connection, the
amber “link” LED on the ETHERNET connector will be lit
solid.
When there is network communication, the green “activity” LED on the
ETHERNET connector and the NETWORK LED on the front of the unit will
flash accordingly.
NOTE:
The 788’s Ethernet port will automatically sense a device-to-device
connection so that a standard straight-through Ethernet cable may always
be used. A cross-over cable is not required.
ARC
ARC
Using a standard straight-through CAT5 cable terminated
with RJ45 connectors or standard shielded twisted pair
terminated with a Euroblock on one end, connect your ARC
Wall Panels to either the ARC or RS-485 ports according to
the guidelines in the ARC Network Design section.
When an ARC Wall Panel network is connected to the 788,
the green ARC LED on the front of the unit will be lit solid
green.
WARNING:
When designing an ARC network, one must be careful
not to double power any ARCs. If all pins on the CAT5 connections are
used, power can travel over the CAT5 cable and reach any ARC on that
particular chain. Power over CAT5 could potentially come from the ARC
that is powered locally and then daisy-chained via CAT5 to other ARCs or
directly from a particular ARC’s terminal block connections. In general, we
recommend using only one type of power connection on
the ARCs, either the RJ45s (with CAT5 cable) or the terminal blocks
but not both.
CAUTION:
DO NOT plug the RJ45 connectors of an ARC Wall Panel into
any RJ45 connector labeled “ETHERNET”, “COBRALINK” or “SYMLINK”.
Refer to the RJ45 Warning for compatibility information.
