Access Control | Installation Turnstile

Once you've purchased your Turnstile, it is time to install it. In this manual you will find all the steps necessary to install the Turnstile.

Chapter 1: Requirements


  • Windows PC
  • Card reader (RFID/Barcode) Compatible readers are listed here and here
  • Turnstile, which can be controlled by a relay (with manual switch / button) 
  • Relay (USB 4 v1.0 KMtronic) 
  • Screw terminal


  • Latest version of the Check-in- client
  • (In some cases) Windows drivers for the card reader


  • USB A-B Printer cable for the Relay -> PC connection (picture)
  • IMPORTANT: if the turnstile is more than 15 feet / 5 meters away from the PC, you will need a special (active) extension cable for the USB connection to work. In example like the one you can buy here. Extend the pair with a regular network cable in between like CAT5e. 
  • In case the computer can't provide the reader with enough power, you also need an USB hub with external power supply like this one. 
  • Intercom cable / installation wire, 2 wires (2 x 0,6 mm²)

Chapter 2: Steps for installation

Below you see a quick overview of the steps to be performed. A more detailed explanation for every step can be found in the following pages.


1. Disconnect the cable from the manual switch

2. Split the cable

3. Reconnect one end of the cable to the switch

4. Connect the other end to the relay

5. Connect the relay and card reader to the PC with the USB cables


6. Download and install the Check-in- client software on the PC (you can find the download link in Business Settings -> Connections)

7. Open the settings of the Check-in- client software and add the reader

8. Add clients to Virtuagym and connect their account to an RFID card or bracelet

Step 1: Disconnecting the cable from the switch

First the switch needs to be disconnected so we’re able to split up the cable. Open up the switch and disconnect the cable from it.

Step 2 & 3: Splitting the cable

After disconnecting the cable from the switch, we’ll need to split up the cable so we can connect the relay as well as the switch. A simple connector strip can be used to split the cable, like shown in figure 4. The cable from the turnstile goes in, and two new cables have to be connected to the other end

Now that we have two cables connected to the turnstile, reconnect the manual switch first, and check if it’s still working. After that the relay can be connected.

Step 4: Connecting the relay

Hold the Relay as shown on figure 5, so you’re able to read the connection types (NO, COM, NC). Relay #1 is the one that’s on the far right on the picture. Now connect the wires to the NO and COM connectors of Relay #1.

Step 5: Connect the relay and card reader to the PC with the USB cables

Now that the relay and the switch are connected to the turnstile, the card reader and the relay can be connected to the PC. This consists of just plugging in the USB cables. When there’s too much of a distance between the PC and the turnstile, it might be convenient to add a USB-hub and/or USB extension to the connection. This will also allow you to tuck away the cables more neatly.

As soon as the devices are connected correctly, lights will turn on on both the relay and the card reader. At this point Windows might install some drivers on the PC, wait for them to finish if that’s the case. That’s the last part of connecting the hardware.
