Wire communications
You must connect each client to a device (such as the Click 400 900 MHz radio) that can convert the serial
communications from the Click 511 into a communication protocol that can travel the necessary distance to
an identical converter that’s connected to the server.
If you use a converter device that can mount on the same T-bus as the Click 511, such as those from the
Wavetronix Click line, the T-bus can pass serial communications between the Click 511 and the converter
module. Alternatively, if you don’t have a T-bus, the RS-232/RS-485 screw terminals on the top of the device
can be used to wire communications to the serial converter device.
To wire your Click 511 devices:
1 Connect your server Click 511 to a converter module such as a Click 400 radio; do this either by
mounting them on the same T-bus or by wiring between the screw terminals.
2 Connect your client devices to the same kind of converter module, either by mounting them on the
same T-bus or by wiring between the screw terminals.
3 If necessary, make a physical connection between the converter modules (for instance, connecting ber
optic or Ethernet cables).
4 If necessary, set the converter modules to communicate with each other using either conguration
soware or on-device conguration features.
e Click 511 has two other communication ports.
˽ RJ-11 jack – for RS-485 communications
˽ DB-9 connector – for upgrading rmware

Wire client digital inputs
Each client Click 511 now needs to be wired to the digital output
device it is monitoring. e digital output device must have an alarm
relay. e alarm outputs of this device will be wired into the digital
input ports of the client. is client will in turn be monitored by the
Click 511 server. For the digital inputs to operate as contact closures,
the DIP switches need to be setup correctly. SW1:2 and SW2:2 should
be on (and the others should all be o).
To wire your digital inputs:
1 Connect a wire to the I1+ screw terminal on the bottom of the Click 511.
2 OPTIONAL: You can connect this wire into a terminal block on the lowest DIN rail in your cabinet.
Using a terminal block with a removable plug simplies wiring by allowing you to wire the plug outside
the cabinet, then plug it back in.
3 Run the wire out of the cabinet and into the input 1 port on the digital output device.
4 Repeat steps 1–3 with a second wire connecting the I1- terminal on the Click 511 to the common port
on the digital output device.
Note. e Click 511 only monitors the rst input (I1). If you would like to use the Click 511 to monitor both
inputs, contact Wavetronix Technical Services.
