Question number FAQ-1304
TS-2600 RS-232C commands
This section explains RS-232C. For parameter settings, please refer to the "Setting Procedure Manual" in the Questions section, and for N-0 settings, please refer to "How to Perform N-0 Settings Using Terminal Mode".
1. Overview
RS-232C is a serial communication interface standardized by the EIA (Electronic Industries Association). The RS-232C interface of this device allows data reading and N-0 correction value writing using appropriate programs on a minicomputer or personal computer. If you have a PC that supports terminal emulator or VT-100 terminal emulator functions, you can write torque zero correction value/N-0 correction value in terminal mode on this device.
2. Specifications
| Standard | Compliant with EIA and JIS X5101 |
|---|---|

| Transmission speed (baud rate) | 9600 bps |
| Character length | 8-bit |

| Terminator | CR ＋ LF |
3. How to connect to a computer
■ Cable wiring
If an external device uses control signals, ignore those signals in the cable wiring or program.
■ Cable wiring example
Compatible connector model (signal cable side): R03-PB3M (manufactured by Tajimi Musen Denki) <Sold separately>
Basic connection (when communicating using only TxD and RxD signal lines)
4. Signal Explanation
| Signal name | Function | Input/Output |
|---|---|---|
| TxD（BA） | Data to be sent | Output |
| RxD（BB） | Received data | input |
| RTS（CA） | Request to send | Output |
| CTS（CB） | Sendable | input |
| SG（AB） | Signal ground | − |
(1) TxD (Transmit Data)
The transmitted data output signal is normally in the MARK state (-9V). +9V level...0 (space)
-9V level...1 (mark)
(2) RxD (Receive Data)
This is the input signal for transmitted data.
+9V level...0 (space)
-9V level...1 (mark)
(3) SG (Signal Ground)
This is a common ground for signals.
5. Function
■ Writing
| Torque zero correction value | CW/CCW 1 point each |
|---|---|
| N-0 Correction Value | CW/CCW 5 points each |
| Auto Zero | Zero correction settings |
■Readout
| Torque measurement value | Parameter setting 1-7/1-8: Average value of the measurement gate time set |
|---|---|
| Rotation measurement value | Parameter setting 1-7/1-8: Average value of the measurement gate time set |
| Set value | Range Factor, P/R, Decimal Point, Torque Zero Correction Value (CW/CCW), N-0 Correction Value (CW/CCW), Rotation Direction, Parameter Settings |
| Signal status | Torque signal input, rotation signal input, READY, trigger |
6. List of Commands
The command terminator is CR (0DH) or LF (0AH), and CR + LF is added to the output from the TS-2600. Xoff (^S: 13H) temporarily stops the output, and Xon (^Q: 11H) resumes it.
■ Data Retrieval
| RTD （Read Torque Data） | The torque value will be read. |
|---|---|
| RRD （Read Revo Data） | The rotation display value will be read. |
| RDD （Read Display Data） | Torque and rotation values are output separated by commas. |
| RLO （Read Logging On） | Separate the torque value and rotation value with a comma. It will continuously output at gate intervals until it receives the "RLF" command. |
| RLF （Read Logging off） | This stops the continuous output caused by the "RLO" command. |
■ Writing settings
Settings cannot be written unless the LOCK switch on the front panel is in the UNLOCK position.| STZn ，d （Set Torque Zero） | n = 0: CW, 1: CCW d = -1, 0 to 99999 This will write the zero correction value for torque. When d = -1, it functions the same as the TRQ ZERO switch on the front panel. |
|---|---|
| STNn ，r（P1）, t（P1）, r（P2）, t（P2）, r（P3）, t（P3）, r（P4）, t（P4）, r（P5）, t（P5）, （Set Torque N-0） | n = 0: CW, 1: CCW r(P1 to P5) = 0 to 99999 (Rotation data for each point: r/min) t(P1 to P5)=0 to ±9999 (Torque data for each point) The N-0 correction value will be written. If the data is valid, it will be sorted in ascending order of rotational value and the N-0 table calculation will be performed. (The correction will be effective if the N-0 switch is ON.) |
| SBD （Set Backup Data） | All backup memory will be written. |
