Python driver for the Galil DMC-30000 series (single-axis) controller, e.g. the DMC-30014.

The driver exposes the controller's two analog outputs (AO1, AO2, +/-10V, 16-bit) and knows nothing about what is wired to them; mapping outputs to a device (e.g. the FSM's X/Y axes) is the job of the higher-level code.

Manuals: datasheet, user manual

for this to work you need to have gclib installed on your machine you can do this on Windows or Linux but on macos you have to do some shenanigins (rosetta 2)

Installing Galil gclib on Linux

python3 -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"
pip install --upgrade --index-url https://www.galil.com/sw/pub/python gclib

check version

import gclib
gclib.version()
# should show 2.5.0

Userflow

Enter python shell with python

Assign IP Address to Galil (If Applicable)

import gclib
gclib.ip_requests()
gclib.addresses()
# find address you want
# define variables mac_address and ip_addr or just input directly
# ip address should be same subnet as host computer
gclib.assign_ip(f'{mac_address}', f'{ip_addr}')

Connect Controller

from dmc30000 import DMC30000
driver = DMC30000()
driver.connect(str(ip_addr)) # ip_addr must be ip address of the galil and be a string

Initialize and Set Analog Outputs

driver.initialize()  # required before AO1 can be used as a general analog output
driver.set_analog_output(1, 0.5)  # AO1 to 0.5 V
driver.set_analog_output(2, -1.0)  # AO2 to -1.0 V
driver.get_analog_output(1)  # voltage currently output on AO1

Disconnect When Done

driver.disconnect()

Useful Other Command

driver._send_command("MG@AO[1]") # or 2
driver._read_reply()

Useful Windows commmands

.\.venv\Scripts\activate.ps1 to activate venv Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass to temporarily allow scripts to run Set-ExecutionPolicy RemoteSigned to perminantly allow scripts to run (requires administrative privileges) ipconfig to find current ip and subnet
