Understand buses

1

e 104 installation process will make more sense if you understand its two buses:

˽ Bus 1: Data – e RJ-11 jacks (for RS-485) and the RS-232 screw terminals

are connected; theyll be used for receiving detection calls

˽ Bus 2: Control – e connector on the back connects to the T-bus (shared

RS-485 bus for multiple Click devices) and is isolated from bus 1; it should be
used to connect to the Click 104 with a computer so you can congure it.

Mount the device

e Click 104 mounts over a T-bus for power and for the control bus (bus 2):

1 If the Click 104 was shipped with the T-bus connector attached, remove the

connector from the module.

2 Snap the connector onto the DIN rail by positioning it over the rail with the

male connector pointing to the right. Hook one arm over the edge of the
DIN rail and press down on the other arm until it snaps into place.

3 Connect the T-bus connector to the rest of the T-bus by sliding them to-

gether until you hear them snap into place.

4 Mount the Click 104 onto the DIN rail: position it properly over the T-bus

connector, hook the lip over the lower edge of the DIN rail, and use a rock­ing motion to snap the module into place.

Wire power and RS-485 communication

If you are using a Click 200 surge protector with the Click 104, power and communication are provided to
the Click 104 through the T-bus (see the Click 200 Quick-reference Guide). If you don’t have a Click 200
surge protector, use the following steps to wire power and communication into the Click 104:

1 Plug a T-bus 5-screw terminal block into the rst T-bus connector.
2 Wire DC power (9–28 V) from the power supply into the rst

screw terminal on the 5-screw terminal block; wire -DC into the
second screw terminal.

3 Connect RS-485 communication (+485, -485 and GND) to the

remaining three screw terminals on the 5-screw terminal block.

Understand the device’s configuration features

e following physical features allow you to congure the Click 104:

˽ Channel LEDs – e top bank of LEDs; these light up to indicate vehicle detection.
˽ Level 2 LEDs – Light up to indicate conguration options. When the device is not in

menu mode, these LEDs are o.

˽ Level 1 LEDs – Light up to indicate menu options while cycling through the menu. ey

also have the following functions:

˿ Red (PWR) – Indicates the presence of power to the device.
˿ Blue (OK) – Indicates the device is operating properly; this LED goes out if the

device is in fail-safe mode.

˿ Green (TD) – Indicates serial communication transmit data on RS-485 bus 1 or 2.
˿ Yellow (RD) – Indicates serial communication receive data on RS-485 bus 1 or 2.

˽ Mode Switch – Lets you cycle through and select menu and conguration options.
˽ Rotary Switch – Aids in input channel mapping.

e Click 104 can be congured in one of three
ways: Click Supervisor, the front panel menu and
the rotary switch. Each option has pros and cons,
and each lets you change dierent parameters;
some parameters can only be set via one option,
while others can be set using any of the three. e
table at right gives you an idea of which parameters
can be set using which conguration options.

NOTE: If the channel input mapping is set by the
rotary switch, it can’t be changed by the front panel
menu or by Click Supervisor.

e rotary switch on the faceplate lets you congure the
channel input mapping—that is, you can map four of the
input data channels coming from the sensor to the Click
104’s four output channels. e outputs are assigned
sequentially, so if you set the switch to 3, then input 9
will be mapped to channel 1, input 10 will be mapped to
channel 2, and so on. See the table at the right for switch/
input channel information.

NOTE: 0 (Soware mode) means that if mapping isn’t set by the rotary switch, it can be changed via the
front panel menu or Click Supervisor.
