Before you can use instruments with the Lager Client (CLI or Python Library), you may need to perform a minimal setup to identify and organize connected devices.

​
View Connected Instruments

To view all instruments currently connected to a specific Lager Box, run: 
lager instruments --box my-lager-box
This command detects and lists all physical instruments connected to the Lager Box via USB or network. To view configured nets (logical mappings to instruments), use: 
lager nets --box my-lager-box
This shows the nets you’ve created, their types, and which instruments they’re mapped to.

​

​
Automatic Net Creation

When an instrument is plugged into a Lager Box, Lager automatically creates a default Net for each function the instrument supports.
  • A simple, single-function device like a power supply will create one Supply Net.
  • A multi-function device like a Labjack T7 DAQ will create several Nets: one for GPIO, one for ADC, and one for DAC.
For instruments that support multiple channels of the same type (e.g., a 4-channel oscilloscope), you can assign and configure Nets for each channel individually.

​
Modify or Assign Nets Using the TUI

For instruments that support multiple channels (e.g. LabJack, PicoScope), you can assign new Nets using the interactive TUI (text user interface). You can also re-name existing Nets. To launch the Net TUI, run: 
lager nets tui --box my-lager-box

​
Within the TUI, you can:

  • Add new Nets
  • Rename existing Nets
  • Delete unused Nets

​
Debug Nets

For debug instruments (e.g., Segger J-Link, ST-Link), you must specify the target MCU when creating the net. This is easily done through the TUI, as it will prompt you to input the MCU type.
Important: The MCU type must match a valid target device supported by your debug probe. If the MCU type is not recognized, the debugger will not function correctly.
