SQN Core Network Configuration and Uses Guide

This document contains the default settings and instructions for configuring the SQN Core Controller.

---

1. Default Network Settings

Upon shipping, the controller is pre-configured with the following factory defaults:

• IP Address: 192.168.10.29
• Port: 80
• Subnet Mask: 255.255.255.0
• Gateway: 192.168.10.1

---

2. Initial Computer Setup

To communicate with the controller, your computer must be on the same subnet. Configure your Ethernet adapter with the following static IP settings:

Setting	Value
IP Address	192.168.10.x (any number 2–254, except 29)
Subnet Mask	255.255.255.0
Gateway	192.168.10.1

3. Updating Controller Settings via Python

You can update the controller's network configuration using the SemiSwitch library.

import semiswitch as sq

# Connect to the controller using default settings
k = sq.Switch(ip_address='192.168.10.29', port=80)

# Set your new preferred network settings
# Replace 'x' with your specific network values
k.set_IP(
    ip_address='192.xxx.xxx.xxx',
    port=xxxx,
    mask='xxx.xxx.xxx.xxx',
    gateway='192.xxx.xxx.xxx'
)

Note: After running the script, a connection error will appear.This is expected. Once the script has executed, the controller will be accessible on the newly configured network.

Quickly press the Reset button more than 10 times to restore the controller to its default network settings.

4. Setting channels

SQN_CoreX controller has X number of channels and are named as dac_01, dac_02, dac_03 and so on.
Each channel can be set from -10V to +10V.

import semiswitch as sq
import time
k = sq.Switch(ip_address='192.168.10.29', port=80)
k.controller.dac_01.set_voltage(6.0) # set Channel 01 to +6.0V
time.sleep(2) #sleep 2 seconds
k.controller.dac_02.set_voltage(-6.0) # set Channel 02 to -6.0V
k.close() #close socket

Multiple channels can also be configured simultaneously

import semiswitch as sq
import time
k = sq.Switch(ip_address='192.168.10.29', port=80)

#create groups of channels   dac_01, dac_03, dac_02, dac_07
channels = sq.DACChannels(pins=[k.controller.dac_01,k.controller.dac_03,
                            k.controller.dac_02,k.controller.dac_07]) 
#set dac_01 = 1V, dac_03 = 2V, dac_02 = 3V, dac_07 = 4V
channels.set_voltage([1.0,2.0,3.0,4.0])             
time.sleep(2)
#set all channels  to 0V
k.set_all_zero()
#set dac_01, dac_03, dac_02, dac_07 all to 5V
channels.set_voltage(5)
#close socket
k.close()

5. Setting RF switch

Four RF switch ports are available (output_0-3). The controller allows only one active port at a time; switching to a new port will automatically turn off the previous selection.

import semiswitch as sq
import time
k = sq.Switch(ip_address='192.168.10.29', port=80)
#switch off all the RF ports
k.open_all()
#switch on the output_0 port
k.output_0.close()
time.sleep(2)
#switch on the output_1 port
k.output_1.close()
#switch off all the RF port
k.open_all()
k.close()
