GPI Outputs
When the eBOX operates as a GPI to Serial or GPI to Ethernet
Converter, it will send to the Doremi server or to Serial Port A status requests on a periodic basis. Replies from the server or deck will be used to establish the state of some of the GPI Output pins, acting as tally lines. The pins are presently defined as:

GPI Tally Outputs in GPI Conversion Modes
Note: by default, the GPI Input pins are active low or 0 volts. That is, events are triggered when the GPI Inputs are connected to ground or driven to zero volts. This behavior can be modified with the eBOX GPI Programmer Software.
