Configure Contact Closure Communications
Each SmartSensor Matrix unit communicates to standard traffic cabinets using
Click! 112/114 detector rack cards. During real-time operations up to four
channels from each sensor can be signaled to a Click! 114 (or to a pair of Click! 112
units daisy-chained together).
Figure 2.7: Click! 112/114 Rack Cards
The rack cards are simple to setup. The cards have been pre-configured using DIP
switches to communicate at 57.6 kbps (the baud rate for SmartSensor Matrix). DIP
switches have also been used to select a group of input channels coming from
SmartSensor Matrix to signal on the Click! 112/114 output channels. The factory
default setting for the Input Mapping switches selects channel group 1.
On a Click! 114 channel group 1 comprises input channels 1-4. When this channel
group is selected; input channel 1 will be mapped to output channel 1, input
channel 2 will be mapped to output channel 2, input channel 3 will be mapped to
output channel 3, and input channel 4 will be mapped to output channel 4.
Note
If you have space in your detector rack, Wavetronix typically recommends
using a 4-channel card. This simplifies the installation process and allows you
to us all four channels from SmartSensor Matrix. If you have a detector rack
that only accepts 2-channel cards (e.g. 170/2070 controller types), then of
course this is your best option. Daisy chain pairs of 2-channel rack cards
together in order to receive all four channels from each sensor. If you do not
have a detector rack in your cabinet, contact Wavetronix technical services for
assistance.
