Simple Access Control System: Use Barcode Scanner RTMU86 Control The Lock Directly, Without Use Access Control Panel.

RTMU86 uploads the scan data to the server and controls the door lock


In most cases, the composition of the access control system is like this: barcode scanner / NFC reader + access control panel + lock + control software/server.

However, if you use our RTMU86, we can make the system more simple.

Firstly, connect use RTMU86 scanner with the lock, and then connect RTMU86 to the server via Ethernet. The scanned content is sent to the server through the Ethernet. After the server verifies the content and sends the unlock command to the RTMU86, the RTMU86 directly controls the lock to be opened. So the solution becomes:

barcode scanner / NFC reader+ lock + control software/server.


Through this solution, we do not need to use the access control panel, thereby reducing the cost and greatly simplifying the difficulty of system integration. So


  1. If you use this solution, customers need to develop/build their own access control management software.
  2. In this article, we introduce a solution without the use of an access controller, but you can also use the RTMU86 to work together with the access controller and then connect with the lock. To learn more about this solution, please read:

Below, we describe the hardware connection and scanner configuration in detail.


1. Hardware connection

(1) RTMU86 connection with a lock

12V is connected to the RTMU86 com terminal input, and NO is connected to the positive pole of the electromagnetic lock power supply. After mu86 receives the unlock command, the com and no ports are turned on, and the electromagnetic lock is energized and unlocked.

Wiegand Barcode Scanner & NFC reader And Access Control Solution



Most of the barcode scanners do not have Wiegand output. In addition, much often when we configure a barcode scanner with an access control panel,  we would meet these problems: 1. the output data are wrong–different from the original bar code content. 2. no output. These problems are usually because the data format does not match the requirements of the control panel. For example data length, ASCII, hex, or direct output data, with or without prefix/ suffix…

Now we can use the RTWG01 Wiegand converter to achieve Wiegand output and solve the above problems. Via this RTWG01, we can easily customize the output data transferred to the access controller board. Data length, ASCII, hex, or direct output data, with or without prefix/ suffix… For example: if a barcode includes information: “William zhang, 2345666677, ****224455555*…” we can pick up number “34566667” or “23456666” or “5666677”…


Firstly, we have the RTMU86 that output by the Wiegand interface directly:


Wiegand NFC and 2D Barcode Scanner: RTMU86




And we also developed solutions for three types of barcode scanners:

1. Wiegand solution for barcode scan engines:

2. Wiegand solution for embedded barcode scanner:

3. Wiegand solution for NFC & barcode scanner:



In this article, we take barcode & NFC reader RTX200 as an example and tell you how to build the solution: configure the scanner and RTWG01 converter, detailed introduction for program the access control software. If you want to learn more about the above solutions for scan engines or embedded scanners, please email us:


A. Hardware preparation:

  • RTX200 Barcode& NFC Scanner
  • RTWG01 converter
  • Type 5 and above 8 core RT45 wire


Hardware connection

Connection diagram

RTX200 output the TTL signal through the RJ45 network cable, the other side of the network cable is connected to the RTWG01 which output with Wiegand signal and then connect to the access controller

Connect RTX200 with Wiegand Converter RTWG01 via RT45 wire cable

Connect RTWG01 Wiegand port using wire to access control board Wiegand port

1.Set output format

Select “Digital char turn Hex” output format

After scanning the barcode, “Digital char turn Hex” converts the digital string to digital output.

For example: scan a barcode “987654321”, and the access controller will also get data”987654321”.

2. Set the Wiegand format

Set the Wiegand format “auto”

Set to auto mode, automatically output the corresponding format Wiegand signal according to the input content length.

  • 0-16777216 output Wiegand 26 signal
  • 16777216-4294967296 output Wiegand 34 signal
  • 429496729-18446744073709551616 output Wiegand 66 signal

3. Save Configuration

Connect RTWG01 with RTX200 scanner, use the scanner to read the configuration code generated by the RTWG01 config Tool.

E. Installation and Setting of Access Control System Software

1. installation AccessControlV7.61en

7. Real-time monitoring

Click Operation ->Real-Time Monitoring

Read NFC card or scan bar code to control switch on/off of the access

F. Intercepting data to output Wiegand signal to access controller

More often, the bar code data or NFC card data exceeds the Wiegand length or contains other non-numeric characters. In these kinds of applications, we need to make the scanner intercept and only pick up the data we want, and then output to the Wiegand signal.

For example: If a barcode contains information “mobile:11223344, “, and we need to intercept the 11223344 only to output via Wiegand interface to the access controller, then we do like this:

Run and Setup intercept function in RTWG01Config Tool

The start bit is the starting position, the length is the intercept length, for the above example: “mobile:11223344,”, to intercepts 11223344, we setup:

“mobile:” length 6 byte and number “1” begin from the 7th

“11223344: “8 bytes long

So set to intercept 8 characters from bit 7

When the length is set to 0, the intercept length is all the remaining data.

For example:

If “6914068019529” and we want to intercept 068019529, it is set to:


You need to set the RTX200 scanner to TTL output of 9600 8-N-1,  then work with RTWG01.
