Configuration
Operating Modes
Ethernet
When the gBOX has an Ethernet Interface installed, it has two
distinct modes of operation that are set by the rear panel DIP
switches. The modes are:
• Server
• Client
The DIP switches are read only at power on so the gBOX must be
power cycled for the changes to take effect.
Serial
When the gBOX has a serial Interface installed, it has just one
distinct mode of operation. This is GPI to serial conversion.
Expander
When the gBOX has an Ethernet or serial interface installed, it is a
master unit, which communicates directly with another master unit
or a host computer.
When the gBOX does not have an interface installed, it becomes
an Expander gBOX. An Expander gBOX adds 48 additional GPI
Inputs and Outputs to a Master gBOX. An Expander gBOX
connects to a Master gBOX using an Expander cable plugged into
one of the Expander ports on the rear panel. Up to 8 Expander
gBOXes can be added to a master gBOX.
