Controller Connections
The first step is to connect one serial (controller) port to one NV9000 system controller and the
other serial port to the other NV9000 system controller.
Each of the NV9000 system controllers must have a serial card installed. (There are several options
regarding the serial cards. Consult your service representative to determine your options.) Depend-
ing on the serial card installed in the NV9000, you will need either a straight-through serial cable or
a cross-over cable. See
, next page.
These are two 8-port examples. There are other types of serial cards. In any case, the protocol is
RS-422, 9600 Baud, 8 data bits, 1 stop bit, no parity.
The second step is to create a registry variable in each of the NV9000 controllers:
The registry variable allows the NV9000 software to monitor the serial port.
The variable is named
SerialMonitor0
, a DWORD, and its value is the serial port number used by
the NV97000 connection. In the preceding illustration, the port number is 5.
The numbering of the serial monitors starts at 0.
To launch the registry editor, choose ‘Run...’ from the Start menu, type ‘regedit’ and click OK:
