54 CHAPTER 7 CLICK 101
e screw terminals labeled C1–C4 represent the common lines for each contact closure
output pluggable screw terminal block (see Figure 7.4):
C1 – e common terminal for digital outputs 1–4.
C2 – e common terminal for digital outputs 5–8.
C3 – e common terminal for digital outputs 9–12.
C4 – e common terminal for digital outputs 13–16.
Configuration Features
e lower section of the faceplate has a push-button labeled Mode Switch, which is used to
initiate conguration tasks. ese tasks will be discussed in the On-device Conguration
section of this chapter.
Installation
Wire the outputs of the Click 101 to a trac controller or other contact closure input. Make
sure that each bank of the four outputs shares a single common wire. Tie each bank’s com-
mon wire to either Logic Ground or the proper common connection.
Note
It is recommended that the sensors not be connected to the T-bus while program-
ming this device with Click Supervisor.
On-device Configuration
e Click 101 can be partially congured using the Mode Switch push-button. is push-
button cycles through two device conguration tasks: autobaud conguration and reset to
factory defaults.
To select a task, hold the push-button down until the corresponding red or green LED
turns on. Once a conguration task has nished, the Click 101 will return to normal poll-
ing mode. During normal polling, the LEDs on the bottom row are used to signal contact
closure outputs.
e autobaud task is initiated by holding the push-button until the green LED lights up.
is task will set the polling baud rate to match that of one of the 10 possible sensor con-
nections. All sensor connections must be at the same baud rate. e default baud rate of the
sensors and the Click 101 is 9600 bps. However, communication modems or other devices
in between the sensor and the Click 101 may dictate the baud rate.
