The VM2710A’s interface is made available on the front panel of the instrument. The
VM2710A-1 will have J201 that contains all signals for this instrument. The VM2710A-2 will
have J201 and J202, while the VM2710A-3 will have J200, J201, and J202. The wiring for each
of these connectors is identical and since each group is treated as a separate instrument, the module
will have three A channels and three B channels.
