Connecting to AT1000 devices

This section describes how to find and connect to AT1000 devices on the network.

Discovering AT1000 Devices

Before a test sequence can be launched (controlling outputs and measuring inputs), and device needs to be found on the network.

The following code will list all devices found on the network and print their serial numbers in the console:

NodeJS

const at1000 = require("at1000");
let devices = at1000.find_devices(5); // Find devices with a 5s timeout
// Loop through devices and print their serial numbers
devices.forEach((device, index) => {
  console.log(`Device ${index + 1}: Serial Number - ${device.get_capabilities().serialnumber}`);
});

Python

import at1000
devices = at1000.find_devices(5)  # Find devices with a 5s timeout
# Loop through devices and print their serial numbers
for index, device in enumerate(devices):
    print(f"Device {index + 1}: Serial Number - {device.get_capabilities().serialnumber}")

The following code will pick the first device in the list and create a tester variable that can be used to control the device. It'll also reset the device to its default state, which is useful if you want to start from a known state.:

NodeJS

const at1000 = require("at1000");
let devices = at1000.find_devices(5); // Find devices with a 5s timeout
let tester = devices[0]; // Pick the first detected device
tester.reset(); // Reset the device to its default state

Python

import at1000
devices = at1000.find_devices(5)  # Find devices with a 5s timeout
tester = devices[0]  # pick the first detected device
tester.reset()  # Reset the device to its default state

Connecting to a specific AT1000 Device

If you know the serial number of the device you want to connect to, you can use the find_device function to directly connect to it. The following code will find a device with a specific serial number and create a tester variable that can be used to control the device. It will also reset the device to its default state.

NodeJS

const at1000 = require("at1000");
let tester = at1000.find_device("12345"); // Find the device with serial number 12345
tester.reset(); // Reset the device to its default state

Python

import at1000
tester = at1000.find_device("12345")  # Find the device with serial number 12345
tester.reset()  # Reset the device to its default state

Note

Some code examples in the next sections of this documentation will assume that a tester variable representing an AT1000 device is already created. The code to find an AT1000 device and create tester variable may not repeated in all example for simplicity and readability.
