HM8112-3S: Performing measurements simultaneously / sequentially without interrupting the BP channel voltage (ID #655)
The HO112 is not designd to supply all scanner ports simultaneously. Only the currently active port is supplied with the voltage set on the BP channel.
This behaviour is based on the hardware inside the HM8112-3. The measured channel needs to switched off, then the next channel become active and the measurement on this channel begins.
The BP channel is used to supply the other channels with a current, e.g. a voltage, that will be provided by an external source. Based on this, it is not possible to switch it on or off with a HM8112-3 remote command. It has to be controled by the external source which is used to supply the scanner card BP port.
More detailed information about the scanner card HO112 you can find in the appropriate manual.
