Lab Switch control utility
|
|
--------------------------
|
|
|
|
If invoked without arguments, labsw prints the firmware version and
|
|
build date.
|
|
|
|
The following commands can be given on the command line:
|
|
|
|
ch1=0, ch1=1, ch2=0, ch2=1
|
|
turn the respective channel on or off. Both relay and
|
|
opto-coupler are switched. Also enters remote mode.
|
|
|
|
query
|
|
read the buttons and opto-coupler inputs (rear panel)
|
|
|
|
local
|
|
exit remote mode
|
|
|
|
The Lab Switch starts in local mode, where the CH1/CH2 buttons
|
|
toggle the respective channel. The main button turns off both
|
|
channels. Local mode is indicated by a green main LED.
|
|
|
|
If a channel is set via USB, the Lab Switch enters remote mode,
|
|
indicated by a red main LED. In remote mode, the channel buttons
|
|
are ignored. Pressing the main button exits remote mode and
|
|
turns both channels off.
|
|
|
|
The lab switch utility currently lacks the following features:
|
|
- access to the rear opto-coupler outputs,
|
|
- switching CH1/CH2 relay and opto-coupler independently,
|
|
- direct control of LEDs.
|
|
|
|
Examples:
|
|
|
|
# labsw ch1=1
|
|
|
|
Turns channel 1 on and enters remote mode.
|
|
|
|
# labsw ch1=0 ch2=0 local
|
|
|
|
Turns channels 1 and 2 off and exits remote mode. This is
|
|
equivalent to pressing the main button.
