ment. Relay-type Outstations are rated up to 1A, 48V and are NOT DE-
SIGNED FOR MAINS SWITCHING.
The Main Units can be controlled by computer via the RS232 interface
also.
Operating Instructions
Unpacking and Connections.
Unpack the Main Unit and place on a flat
surface within easy reach of the operator. Set up the preferred mounting of
the Main Unit by removing the bracket securing screws on each side of the
Main Unit and repositioning each bracket for either 19” 2RU rack mounting
or freestanding, and then replace and tighten the bracket securing screws.
Mount the Main Unit in the rack unit if this is the preferred mounting con-
figuration.
If multiple Main Units are being used and linked, mount these also and
connect to each other using the RS232 (serial) connectors (loop output
from Main Unit one to input of Main Unit two etc).
Unpack the Outstations and install where required. Connect these to the
Main Unit using high quality, standard 3 pin XLR (mic) cables (refer fig 1
for connection options).
Apply power to the Main Unit/s using the 12V DC power adaptor/s pro-
vided and switch on the mains power. All LEDs in the system illuminate
briefly to confirm that all are operational. The system is now ready for pro-
gramming or operation.
Programming Outstations
1.
With the system fully powered up, unplug the XLR input cable
which is providing power to the Outstation and wait 10 seconds for
the Outstation to fully power down (i.e. until all LED lamps on the
Outstation are fully extinguished).
2.
While holding down the ‘Confirm’ button, reconnect power to the
Outstation. Release the ‘Confirm’ button and the ‘Standby’ light will
flash to confirm the Outstation is now in programme mode
