CHAPTER 10 • CLICK 513 103
˽ RS-485 T-bus connection port
˽ RS-232 front DB-9 connection port
˽ RS-232 top screw terminal connection port
˽ RS-485 top screw terminal connection / front RJ-11 jack connection port
The back of the Click 513 features a 5-position connector that plugs into a T-bus connector
and provides power and RS-485 communication to the device. It also passes RS-485 com-
munication to all other devices on the T-bus. Usually, the RS-485 T-bus connection port is
the primary connection to the SmartSensor HD.
The RS-232 DB-9 port on the front of the module is used when interacting with a computer.
This can be when using Click Supervisor or when connecting to a serial terminal program
such as Windows HyperTerminal.
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 other two communication ports can be accessed via the screw terminal blocks on the
top of the device. However, in many Click 513 applications these ports are unused. The first
block has -485, +485 and two ground screw terminals for wiring RS-485 communication.
These ports are used to talk to a Click 172 or 174. The RS-485 communication lines of this
block are physically connected to the RJ-11 jack on the front of the module, so a connection
can be made with the RJ-11 jack or by wiring the RS-485. The second block has a -232, +232
and two ground screw terminals for wiring RS-232 communication.
Note
The Click 513 operates at a baud rate of 9600 bps.
There are digital I/O ports on the bottom of the module that allow you to interact with
contact closure and digital I/O systems (see Figure 10.3).
