Simulate enable

The simulate enable jumper is used in conjunction with the Analog Input (AI) function block
simulation. The jumper is also used as a lock-out feature for the AI function block. To enable the
simulate enable feature, the jumper must transition from OFF to ON after power is applied to the
transmitter, preventing the transmitter from being accidentally left in simulator mode.
