CHAPTER 28 CLICK 400

Autobaud (solid green)

The Autobaud mode is used to match baud rates with an external device. By default, the

device will attempt to match baud rates with a SmartSensor on the bus; however, the device

can be configured to autobaud with any device that supports a serial interface.

During the autobaud process, the green LED will stay on and the red LED will flash after

every autobaud cycle (the cycle time increases as latency is added after each cycle). If the

autobaud was successful, the radio will be set up as a client and the green LED will turn off

and the yellow LED will start to flash as data arrives over the bus; if the autobaud was not

successful, the green LED will turn off and the yellow LED will be solid.

Link Test in Server (flashing blue) and Client (solid blue) Modes

The Link Test modes are used to test the wireless link between two Click 400 modules. Fol-

low the steps below to perform a link test:
1 Set one of the devices in Link Test mode as a server by pressing the push-button, then

releasing when the blue LED begins flashing. A server in Link Test mode will have a

solid blue and red LED and the green LED will begin flashing as it sends data for the

test.

2 Set the other device in Link Test mode as a client by pressing the push-buttonm then

releasing when the blue LED turns on solid. The client device will have a solid red LED.

3 Watch the client to be sure it has found a server: if the device finds a server on the same

channel, the blue LED will be solid. If the blue LED does not turn on, then the client

cannot find a server.

4 Once you’re sure the client has found a server, watch the LEDs on the client to see the

results of the link test. A blinking green LED means that the client is receiving valid

link test data from the server; a flashing yellow LED means that the device is receiving

invalid link test data; and a solid yellow LED means no data is being received.

5 If the Click 400 is receiving invalid link test data, verify that the server is in link test

mode. If this does not fix the problem, then check the line of sight and the antenna for

possible problems.

6 Once the test is complete, the devices must be taken out of link test mode in order to

operate. Press and release the mode button on each device to get back to operational

mode.

Factory Reset (flashing red)

The Factory Reset operation will erase all user-configured fields and the Click 400 may have

to be reconfigured to work properly in its current application. If a device is not respond-

ing and not communicating, resetting the device may fix the problem. Once the device

is responding, restore the configuration needed for its current application (i.e. loading a

SmartSensor client driver or changing to the correct channel).

To reset the Click 400 to factory defaults, release the push-button when the red LED begins
