Control the ICStation USB multi channel relay modules
IcseCtl is a library to control the ICStation USB multi channel relay modules (ICSE012A, ICSE013A, ICSE014A).
The initialization of the devices is handled by udev. To set up udev:
sudo cp examples/icseudev.py /lib/udev sudo cp examples/99-icsectl.rules /etc/udev/rules.d sudo udevadm control --reload-rules
When a device is plugged in the relays are switched on by default. After detection the icseudev.py script switches them off.
Symbolic links /dev/ttyICSE012A, /dev/ttyICSE013A, /devttyICSE014A are created if a respective device is connected. If another PL2303 device is connected a link /dev/ttyPL2303 is created.
Initialization is logged in the system log.
Per default, only root is allowed to use devices directly. On Debian and Ubuntu serial USB devices are assigned to group dialout. To allow a user to use the device call:
adduser USER dialout
The script examples/icsectl can be used to switch individual relays. The status is kept in a file in the user’s home directory. If the file does not yet exist, it is assumed that all relays are switched off.
