Section 1: Introduction- Detailed Description of Functions

RS-232 PORT FUNCTIONS

RS-232 Port- The RS-232 (serial) port is used to communicate with the CM16a for Ethernet address setup purposes and other diagnostic purposes. Most users will never have a need to access the RS232 port, but for customized networks and for troubleshooting system problems, it may be necessary.

For the RS-232 port utilities, see the Operation section, “Serial Port I/O Interface”. This section outlines the proper connection and communica- tion settings required to communicate with the CM16a via the serial (RS232) port.

If the CM16a is connected to an Ethernet network where the factory-provided Ethernet address informa- tion is not acceptable, a configuration utility must be run. This involves connecting a computer with a prop- erly configured serial port to the CM16a using a null- modem type cable (such as a “Laplink” cable) and running a dumb-terminal program (HyperTerminal is the Microsoft® Windows- supplied program). DO NOT CHANGE THE FACTORY SETTINGS UNLESS YOU ARE CERTAIN OF WHAT YOU ARE DOING! If addressing is configured incorrectly, the CM16a may not respond to network control.

CONTACT CLOSURE I/O FUNCTIONS

RLY OUT- This is used for remotely controlling an electrical device in an on/off manner (such as a cooling fan, an audible alarm, a light, etc.). An internal SPDT (single-pole, double throw) relay is controlled by soft- ware command. Its contacts are accessible at the rear panel RLY OUT connector and are labeled:

NC (normally closed)

NO (normally open)

C(common)

RLY/TRG IN- Detects the closure (or opening) of a switch connected to the RLY/TRIG IN terminals on the rear panel. Also accepts CMOS and TTL logic-level inputs. An example is the detection of a limit-switch that indicates an open door on an equipment cabinet.
