LakeShore218 Satellite

Name	LakeShore218
Description	Satellite controlling a LakeShore Model 218 temperature monitor
Language	Python

Description

This satellite uses the RS-232 serial port of LakeShore Model 218 temperature monitors to read the temperature of the connected temperature sensors.

Note

This satellite requires write access to the serial port or USB-to-serial converter the device is attached to. It is recommended to not run this satellite with root privileges but to allow the regular user access to the required port instead. On Unix, if the port is e.g. /dev/ttyUSB0, the group can be found via stat /dev/ttyUSB0 (the Gid entry). If the group is e.g. dialout, the permissions can be given with sudo usermod -a -G dialout $USER. A restart is required for the changes to be effective.

Note

Since the LakeShore Model 218 has a male RS-232 connector, most USB-to-serial converters require an adapter. This adapter has to be a null modem, where the TX and RX lines are switched.

Requirements

The Keithley satellite requires the [visa] component, which can be installed with:

Source

pip install --no-build-isolation -e .[visa]

PyPI

pip install ConstellationDAQ[visa]
