GymMaster RFID Reader Instructions

Please Note:

These instructions are for configuring RFID Readers using the older Desktop version of GymMaster. All new installs of GymMaster are web-based, providing easier installation for you and more overall functionality.

If you have a GateKeeper unit, please see the GateKeeper Instructions


All the RFID readers have serial-port connections. Some have been designed with a serial connection which is USB-shaped. This can be somewhat confusing, especially if you have only ever dealt with USB connections before. Because they have serial connections, all readers will therefore need a serial-port device driver to be installed in Windows, before Windows will be able to recognise the device now plugged in. The unit will be supplied with a specific cable type, check this carefully. This will indicate what sort of driver is needed. Most have a serial-to-USB converter within the unit housing, so these readers are supplied with a USB-at-both-ends cable connection. Others have a cable with a USB connection at one end, and a serial connection plus a USB connection at the other end. In this case, the serial connection transfers data, the USB connection simply provides power to the RFID reader. Both need to be connected to the computer.

Settings → Preferences → Card Readers tab → click Card Reader Hardware Setup
