34 CHAPTER 3 • CONTACT CLOSURE COMMUNICATION
4 Connect a 6-ft. (1.8-m) patch cord from the Click 222 RS-485 B port to a bus 1 port on
another rack card.
5 If you are using Click 112 cards, use an 6-in. (15-cm) patch cord to share bus 1 between
cards dedicated to the same sensor. Also, configure one card to use Matrix channels 1
and 2 and configure the other card to use Matrix channels 3 and 4. If you have more
than two sensors in your system, repeat steps 2–4 to connect bus 1 for all remaining
rack cards.
6 Connect a 5-ft. (1.5-m) patch cord from one of the Click 222 bridge ports to bus 2 of
the rack cards.
7 Use the 6-in. (15 cm) patch cords to create a daisy-chain that shares bus 2 between all
of the rack cards. Bus 2 will be used for device configuration.
Click 112/114 LEDs
Once you have completed the wiring, check the Menu Level 1 LEDs, which have both
menu-indicating and general status–indicating functions. The list below contains informa-
tion on the general status–indicating functions of the LEDs:
˽ PWR (red) – Indicates the device is powered.
˽ PU (blue) – This LED is not associated with any general status function and should
remain off while the card is in normal operating mode.
˽ TD (green) – Indicates the card is transmitting serial communication.
˽ RD (yellow) – Indicates the card is receiving serial communications.
The red LED should be on, showing the card is powered and operating normally.
The list below contains additional information about the rest of the LEDs:
˽ Detection Channel LEDs (red) – Indicates when a call is placed on the corresponding
contact closure output channel.
˽ Menu Level 2 – Used for the configuration menu that is activated using the Mode
switch.
˽ General Status (Menu Level 1) – In addition to the functions listed above, these are
used to cycle through and select options from the front panel menu.
