Channel Bits
Channel bits 0 to 3 allow to define a channel-dependent four-bit binary value to control four independent
output signals (lines 8 to 11 at the USER CONTROL connector). The output signals are 3.3 V TTL signals
which can be used to differentiate between up to 16 independent analyzer states.
Since firmware version 3.70 it is also possible to use Drive Port Pins (lines 16 to 19 at the USER
CONTROL connector) as additional channel bits 4 to 7, which allows to differentiate between 256 states in
total.
Use Drive Port Pins as Channel Bits will only take effect if lines 16 to 19 are not used as Segment
Bits.
Setting the channel bits does not change the analyzer state.
In contrast to most other settings in the System Config dialog, the Channel Bits settings are stored in
the current setup, i.e. a *RST or Preset resets them to their respective defaults (no output signals at pins 8
to 11, pins 16 to 19 not used as channel bits).
For an application example refer to the detailed remote control description.
