On a Click! 112 channel group 1 comprises input channels 1-2, where input channel
1 will be mapped to output channel 1 and input channel 2 will be mapped to output
channel 2. In order to map input channel 3 to output channel 1 and input channel 4
to output channel 2, you will need to select channel group 2. There are three ways
to select channel group 2: using DIP switches, using the Mode Switch on the
faceplate, or using Click! Supervisor.
The DIP switches override the Mode Switch and Click! Supervisor, so if you are
planning on using either the Mode Switch or Click! Supervisor then you will need to
first check that the DIP switches are set to allow for software configuration.
One benefit of using DIP switches to select the channel group is that if you ever
have a field service call and need to replace a Click! 112, all you need to do is
match the pattern of the DIP switches on the card you are replacing. This paradigm
will even work in situations where the old rack card will not even power up.
On the other hand, a benefit of using the software configuration is that you can
remotely manage the configuration of the cards (assuming you have interconnect to
the traffic cabinet and a Click! 301 or equivalent device on the Command and
Control Bridge). In this paradigm, it becomes the responsibility of the traffic
manager in the operations center to keep a record of how each card was
configured.
Tip
The status of SmartSensor Matrix output channels are sent using a contact
closure serial communications message (see Figure 2.8). Bits within the
message are dedicated to channels 1, 2, 3, and 4. If the designated bits are
set to 1 the associated channel is on (contact closed on rack card), and if they
are set to 0 the associated channel is off (contact open on rack card). When
the serial message sent by a SmartSensor Matrix reaches a rack card the
sensor output channels are now considered rack card input channels. It is then
the job of the rack card to relay the status of the input channels (sensor output
channels) to the selected rack card output channels.
