Summing a large constant value with the signal will switch that channel into Open
mode. The values in the Config DataTable must be outside the maximum stimulation
range. A value of +10000 is sufficient to open a channel. A value of 0 in the
Config data table will have no effect on the output signal.
Monitoring the Stimulation
Eight PCM A/D converters on the stimulator monitor the actual output voltage for a
chosen bank of channels and send that information back to the RZ. This information
is available from the output of the IZ2_Control macro. The MonBank macro input
specifies which bank of eight channels is updating on the Monitor output (the rest of
the channels of the Monitor output will be latched). A zero indicates that the first
bank of eight is monitored.
Note: The onboard A/D converters provide the feedback clip at +/-20V, which is higher
than any possible output.
