How to Remotely Control GYRFALCON S8000 & S4000 Pro via SCPI

A practical walkthrough of communication setup, core commands, typical workflows, and complete scripts for four-channel automated battery testing.

Introduction

The ENOVA GYRFALCON S8000 and S4000 Pro four-channel smart chargers are not only operable via the front panel, but also provide a complete SCPI (Standard Commands for Programmable Instruments) command interface. With SCPI, you can seamlessly integrate the charger into TestController, LabVIEW, Python, C#, and other host software to achieve:

• Four-channel independent control — manage charging/discharging tests on 4 channels simultaneously.
• Automated test workflows — batch configure 32 programs and execute cyclic tests in sequence.
• Real-time data acquisition — periodically read voltage, current, capacity, and energy.
• Remote monitoring and alerts — obtain device information via status queries and LED states.

This article walks you through SCPI remote control of GYRFALCON, from communication setup and core commands to typical workflows and complete scripts.

1. Communication Setup

The host communicates with GYRFALCON via USB-to-serial (CH340C). Parameters:

TestController configuration example:

#port comFixedBaud
#baudrate 115200
#driver SCPIx

2. Core Command Categories

2.1 Measurement and Status Queries

MEASure:ALL? return format breakdown (4 values per channel):

MEASure:ALL? 1,2,3,4
Return: 4.183e+00, 3.510e-01, 2.048e-02, 8.540e-02, 4.202e+00, ...
              ↑             ↑             ↑             ↑             ↑
          CH1 volt      CH1 curr      CH1 cap      CH1 energy    CH2 volt ...

2.2 Program Parameter Settings

2.3 Program Control Flow

Complete program setup flow: Preprocess → Set parameters → Save → Start → Wait for completion → Release control

2.4 Super Control

Super control allows real-time adjustment of key parameters during program execution, such as charge current and termination voltage:

2.6 Dangerous Commands Warning

3. TestController Integration Example

TestController is an open-source host testing software that maps SCPI commands to UI controls via configuration files. Key configuration snippets:

#askValues MEASure:ALL? 1,2,3,4
#askValuesReadFormat ffffffffffffffff
#readingDelay 5
#interfaceType Charger Charger:2 Charger:3 Charger:4
#interface readVoltage   0 4 8 12
#interface readCurrent   1 5 9 13
#interface readCapacity  2 6 10 14
#interface readEnergy    3 7 11 15

Program parameter setting example:

#scpiCmd ChargeCurrent tx PROGram:CURRent:CHARge (selectedChannel),(value)A
#scpiCmd ChargeCurrent? txrx? PROGram:CURRent:CHARge? (selectedChannel)
:readmath: (value/1000.0)

Super control button example:

#cmdSetup button Start_Process CH1_Super_Controller
:write:SUPEr:CONTrol:RUN Ch1;[200];
:tip:The button start the program.
