CHAPTER 11 • CLICK 514 119
˽ RS-232 top screw terminal connection port
˽ RS-485 top screw terminal connection / front RJ-11 jack connection port
The back of the Click 514 features a 5-position connector that plugs into a T-bus connec-
tor and provides power and RS-485 communication to the device. It also passes RS-485
communication to all other devices on the T-bus. The RS-485 T-bus connection port is the
primary connection to the check-in and check-out SmartSensor HD.
The RS-232 DB-9 port on the front of the module is used when interacting with a computer
to use Click Supervisor or a serial terminal program. (The RS-232 port on the top of the
module can also be used for this purpose.)
Warning
With older versions of the Click 500 series module, it is necessary to remove pin 4
from the serial cable to prevent the device from going into Program mode. If it enters
Program mode, all of the faceplate LEDs will turn off, and power will need to be cycled
on the device.
The RS-232 and RS-485 communication ports can be accessed via the screw terminal blocks
on the top of the device. The first block has -485, +485 and two ground screw terminals for
wiring RS-485 communication. The RS-485 communication lines of this block are physi-
cally connected to the RJ-11 jack on the front of the module, so a connection can be made
either with the RJ-11 jack or by wiring the RS-485.
The second block has a TD and RD for wiring RS-232 communication. The ground for RS-
232 communication is on the first block.
Note
The Click 514 operates at a baud rate of 9600 bps.
While the device, as a Click 500 series module, also has two digital inputs ports (first block
on the bottom) and two digital output ports (second block on the bottom), the standard
Click 514 application does not use these. The Click 500 series module also has two DIP
switches on the left side of the module. The DIP switches are used to program or reprogram
the unit; however, for normal Click 514 operation all DIP switches should be in the OFF
position.
