ports. However, only the RD (yellow) light will flicker in this case. The TD (green) light is
reserved for data originating from the Click 511.
Example
If you send a message request to a SmartSensor 105 via the Click 511 RS-232 front
DB-9 connection port you will see the following: the RD (yellow) light flickers once
when the message request is received and then forwarded to the sensor (e.g. via an
RS-485 port). The RD (yellow) light flickers again when the message response from
the sensor is received by the Click 511 and forwarded to the RS-232 front DB-9 con-
nection port. The TD (green) light will not flicker at all in this example.
Located on the front of the module below the DB-9 connector is a push-button labeled
Mode Switch. The push-button allows you to make selections from the menu. See the Op-
erating Modes section of this chapter for more information.
Installation
Make sure that the Click 511 is installed on a T-bus with active power and RS-485 com-
munication.
If you are going to use your Click 511 in conjunction with a computer serial port and ter-
minal program, make sure there is a serial connection between the computer and the Click
511 or between the computer and another device on the same T-bus as the Click 511.
Obtain the desired serial terminal program and follow the distributor’s instructions for in-
stallation.
Operating Modes
The Click 511 has two operating modes and two tasks (Client, Server, Server Output Setup,
Reset). These modes are accessed through the mode menu, which is controlled via the push-
button; the system (multicolored) LEDs light up to show which mode you are currently on.
Table 8.1 shows the LED color and state associated with each operating mode or task. If the
operating mode uses a flashing LED state, the LED state will be different during the menu
selection process and when the operating mode is finally selected. This dual flashing meth-
odology helps avoid confusion when a mode is operating and the green or yellow LEDs
flicker to indicate serial data activity.
