Transceiver Power Interface, J1
Terminal block, J1, on the Evaluation PCB, provides direct access to the two
power lines feeding the transceiver module—unregulated primary power
(6–30 Vdc) and regulated 3.3 Vdc.
These jumpers and nearby eyelets can be used for two functions: 1. Measure
the module current consumption under various operating conditions by
inserting an inline ammeter, and 2. To bypass the Evaluation PCB’s 3.3 Vdc
regulator to connect your own power source.
With the jumpers removed, the pins of J1 can be used as convenient points to
measure the regulated and unregulated power supplied to the OEM module.

NOTE: Jumper J1 does not normally require any change by the user for basic
operation of the transceiver module on the Evaluation PCB.Both jumper
plugs are normally installed on J1.
