tion. The first block has -485, +485 and two ground screw terminals for wiring RS-485 com-
munication. These RS-485 lines are physically connected to the RJ-11 jack on the front of
the module. The second block has a -232, +232 and two ground screw terminals for wiring
RS-232 communication. In many 510 troubleshooting applications, the terminals on these
two blocks are unused.
The front of the module has an RJ-11 jack for RS-485 communication. This jack is physi-
cally connected to the RS-485 communication lines of the RS-485 pluggable screw terminal
block on top of the module.
The front of the module also has a DB-9 port for RS-232 communication. This port per-
forms differently than similar ports on many other Click modules. While it can be used
to convert RS-485 communications to RS-232, this is not its normal usage. Instead on the
Click 510 this port is normally used to upgrade the Click 510 program or reprogram the
unit for custom applications. However, if you are using a modified RS-232 DB-9 serial cable
connector (with the DTR pin removed) it can be used to convert RS-485 communications
to RS-232.
Note
If this pin is not removed or disabled using terminal software like Docklight, the Click
500 will enter Program mode when a connection is made using Windows HyperTer-
minal. In Program mode all of the faceplate LEDs will turn off. To exit Program mode,
power cycle the device.
While the device, as a Click 500 series module, has two digital/output ports, the standard
Click 510 application does not use these.
Any data on one port will be transmitted simultaneously on all other ports.

The following are features of the Click 510 used for configuration.
