usbrelay1
Control or query usb hid relays
Usage
usbrelay [OPTION ...]
[ACTION ...]
Overview
usbrelay allows for querying and setting the state of USB HID electrical relays. If no ACTION is passed, the state of all relays is printed to stdout. RELID_N=[0|1] sets the N-th relay on module RELID to off or on.
Multiple actions can be performed with one command
eg:
usbrelay REL0A_1=0 REL0A_2=1 REL0B_2=0...
The Relay module ID can be changed on DCTTECH relays: RELID_0=NEWID sets the relay RELID to NEWID
