The ICStation USBRelay is a USB relay card with up to 8 relays. Models with 2 (ICSE013A), 4 (ICSE012A) and 8 (ICSE014A) relays exist.
See Info for USB details.

The relay boards have a very simple and limited protocol.
Note: Once the device has entered the command mode (0x51), every following byte will be interpreted as a bit mask for switching relays. When reconnecting to the device (e.g. with sigrok-cli or SmuView) the connect will fail unless you have repowered the device!
|0x50|| Query the device model.
|0x51 0xnn 0xnn ...|| Start command mode.
Every following byte will be interpreted as a bit mask for switching the relays. 0 will turn a relay on, 1 will turn a relay off.
Note: You cannot leave the command mode!
Examples for switching mask bytes (ICSE014A, 8 relays):
Detect the device and display its properties.
