Wavetronix SmartSensor Matrix (SS-225) - User Guide - Manual (Page 31)

30 CHAPTER 3 • CONTACT CLOSURE COMMUNICATION
Note
See the Click 100–400 Series User Guide for complete information on how to con-
nect and configure the Click 104 DIN rail contact closure module and the 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 Click 104 (or to a pair of Click 112 cards daisy-chained together).
Each SmartSensor Matrix could potentially use up to 16 channels using a combination of
Click 104/112/114 contact closure modules. This means that a standard four-approach stop
bar detection system can be accommodated by a 64-channel detector rack.
The Click 112/114 cards can be configured using DIP switches on the circuit board, the
front panel menu on the faceplate or Click Supervisor. The Click 104 can be configured us-
ing the rotary switch, the front panel menu on the faceplate or Click Supervisor.
Using the Click 112/114 DIP Switches
The DIP switches allow you to program the baud rate and input mapping using the hard-
ware. If the Click 112/114 cards are programmed using the DIP switches, the settings can be
viewed, but not modified, using the front panel menu or Click Supervisor.
If you are planning to use either the front panel menu or Click Supervisor to program the
device settings, then you will need to first make sure that the DIP switches are set to allow
for software configuration; to set this, simply make sure that all relevant switches are turned
off (see Figure 3.2).

There is no need to change the baud rate of the Click 112/114 cards from the factory default
of 9600 baud. The settings for the input mapping, however, will need to be set. This process
is explained in the following sections.
