6.1.1.
Local port (Front panel)
The relay has a USB-connector in the front panel
Protocol for the local port
The front panel port is always using the command line protocol
for VAMPSET regardless of the selected protocol for the rear
panel local port.
If other than “None” protocol is selected for the rear panel local
port, the front panel connector, when activated, is still using
the plain command line interface with the original speed,
parity etc. For example if the rear panel local port is used for
remote VAMPSET communication using SPA-bus default
9600/7E1, it is possible to temporarily connect a PC with
VAMPSET to the front panel connector. Connecting a cable
between the PC and the relay will create a virtual com-port.
The default settings for the relay are 38400/8N1. The
communication parameter display on the local display will
show the active parameter values for the local port.
Physical interface
The physical interface of this port is USB.
