Connectors
Connecting DC power
Connect DC+ (red wire) to DC out + from your DC supply.
Connect DC- (black wire) to DC out - from your DC supply.
Do not connect the white wire nor the blue wire in the power cable, unless you
want to use the Remote on/off function or the On/off control function.
Connecting Remote on/off (ON_IN)
With the Remote on/off function you can switch the Message Terminal on and
off from a remote location, without using the on/off button on the terminal. To
connect the Remote on/off function in the Message Terminal, do as follows:
1. Connect DC+ and DC- as described in the previous section.
2. Connect a switch to the
white wire
in the power cable (pin 3, ON_IN, in the
Power connector.)
3. Connect the other side of the switch to the
black wire
in the power cable
(DC- (0 V DC) in the Power connector), with a resistance below 10 k
.
To switch on the Message Terminal
, close the switch. When the switch is
closed, Pin 3 in the Power connector is connected to DC-.
Connecting On/off control (ON_OUT)
You can use pin 4 in the Power connector (blue wire) to switch other units on
and off when the Message Terminal is switched on and off. How to connect
this pin depends on the units you connect.
The function of pin 4 is as follows:
•
Message Terminal off: Pin 4 is high (DC+ i.e. between 10.8 V DC and
32 V DC).
•
Message Terminal on: Pin 4 is low (DC- from the power supply, with 10 k
serial resistance)
Note
When the remote switch is closed (the Message Terminal is switched
on), you cannot use the Power button on the Message Terminal.
