Terminal
The VX 820 connects to a VeriFone terminal via a straight cable. There is a
minimum power requirement for the VX 820, currently specified as 4.2W. In cases
where the terminal is only able to provide a 7 V DC output to power the VX 820,
the terminal must be able to source at least 0.57 A of current. Otherwise, proper
functioning of the VX 820 is not guaranteed.
