Select the channel to be set up for high impedance control with the up and down arrow buttons.
Select one of Off, Internal, External, and Both.
Table 3 19: Impedance state contol methods
Selection item Description
OFF No high impedance control (output is always enabled)
Internal Controlled by the channel 0 signal (high impedance when high)
External Controlled by an external impedance control signal (high impedance
when high)
Both Controlled by both the channel 0 and external impedance control
signals (high impedance when either signal is high)
Since the channel 0 signal for each output cannot control its own high-imped-
ance state, these channels must be set to either OFF or External. Figure 3-54
shows a schematic overview of the high-impedance control circuit.
