Figure 1: IO extender schematic
The IO Extender V2 can be connected via the input connector (left connector in Figure 1) to the
Gatekeeper. The multiple output functions are presented to the user via the output connector
(right connector in Figure 1).
Depending on the configuration of the Gatekeeper it is connected to there are two jumpers that
need to be set. Setting these jumpers determines if the corresponding IO on the Gatekeepers
port will be used as an output or input. By default, these are both set to output.
IO Extender V2 modules are interchangeable under the condition the jumpers are set to the
configuration of the connected Gatekeeper.
The functions per connector are listed in Table 1-4.
