The
Configure
button will be enabled. Click this button to determine the method of
connecting the control links between the two Multi Scan NXA83.
NXA83_Port-Configuration_Host-Comms_Redundancy-Settings
There are five options to select from:
•
COM ports 1 and 2 used for Control Ports
: The Multi Scan NXA83 automatically
configures the communications ports for redundancy. Ensure that COM 1 and COM 2 are
NOT selected as "In Use" as either Host or Slave ports. Connect a Serial Cross-over lead from
COM 1 on one Multi Scan NXA83 to COM 2 on the other for both Multi Scan NXA83. This
is the recommended method of connecting the control links.
•
COM ports 7 and 8 used for Control Ports
: The Multi Scan NXA83 automatically
configures the communications ports for redundancy. Ensure that COM 7 and COM 8 are
NOT selected as "In Use" as either Host or Slave ports. Connect a Serial Cross-over lead from
COM 7 on one Multi Scan NXA83 to COM 8 on the other for both Multi Scan NXA83.
•
Manual Selection of Control Ports
: This option must be selected when the control ports
have been manually configured. There must be two control ports configured:
– 1 DCC Host port configured as a Redundant Link Control protocol.
– 1 DCC Slave port configured as a Redundant Link Control protocol.
These can be either standard RS232 COM ports (recommended for manual configuration)
or Network ports. The communication parameters should be set identically for both Multi
Scan NXA83.
