The CFG Interface
Purpose The CFG port is the connection point to the island bus for either a computer running
the Advantys configuration software or an HMI panel.
Physical
Description The CFG interface is a front-accessible RS-232 interface located behind a hinged
flap on the bottom front of the NIM:
The port uses a male eight-pin HE-13 connector.
Port Parameters The CFG port supports the set of communication parameters listed in the following
table. If you want to apply any settings other than the factory default values, you
must use the Advantys configuration software:
Parameter Valid Values Factory Default Settings
bit rate (baud) 2400 / 4800 / 9600 / 19200 /
38400/ 57600 9600
data bits 7/8 8
stop bits 1/2 1
parity none/odd/even even
Modbus communications mode RTU/ASCII RTU
Note: To restore all of the CFG port’s communication parameters to their factory
default settings, push the RST button (See The RST Button, p. 55) on the NIM. Be
aware, however, that this action will overwrite all of the island’s current
configuration values with factory default values.
You can also password protect a configuration, thereby putting the island in
protected mode (See Protecting Configuration Data, p. 164). If you do this,
however, the RST button will be disabled and you will not be able to use it to reset
the port parameters.
