This a PyTango device server for controlling Kepco power supplies using Serial-to-GPIB-adapters. It uses the standard command strings needed for controlling a Kepco GPIB power supply, but sends them to a serial ttyDevice instead of a real GPIB port. It thus allows converting a GPIB-controllable Kepco to a serial device.
Create a udev rule in order to mount the USB Serial converter always under the same link, e.g. /dev/ttyKepco.
First check the VendorID, ProductID, and SerialNumber using dmesg. Then add a new udev rule:
sudo nano /etc/udev/rules.d/55-usbcom.rules
SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{serial}=="PX4UALD3", SYMLINK+="ttyKepco", MODE="0666"
Reload and apply the udev rule by
sudo udevadm control --reload
sudo udevadm trigger --action=add
The PyTango device server does not allow to configure parameters specific to the GPIB protocol. This has to be done before in the respective Serial-to-GPIB adapters, which usually allow to set its own GPIB address as well the address it will talk to, as well as other parameters via specific control strings or via a configuration utility provided by the manufacturer. Don't forget to save the parameters in the adapters non-volatile memory.
