CHAPTER 9 CLICK 110

Physical Features

The following sections describe the physical features of the Click 110 card.

Figure 9.2 – Diagram of the Click 110

Communication Ports

The Click 110 contains two independent serial communications ports. Each port is made

up of two RJ-11 connectors, which make it simple to daisy-chain multiple Click 110 cards

together and create a RS-485 bus. The two RJ-11 RS-485 data buses can be connected to a

SmartSensor through a Click 200 surge protection module, or through a serial data con-

verter.

Typically, one bus is used to report vehicle data, and the other is used for configuration. As

both buses are identical it does not matter which is used for data or configuration. Alterna-

tively, a single bus could be used for both data and configuration, but data reporting would

be temporarily halted during configuration. During this time, the Click 110 will enter fail-

safe mode if vehicle data is not reported for ten seconds.

LEDs

The faceplate of the Click 110 has four banks of LEDs. The top bank is used for detection in-

dication, the second bank for fault indication, the third for menu indication, and the fourth

for menu indication as well as operation states.
