R16-7B UHF RFID Reader
Wiring Diagram
SWD
There is a 4 pin header for SWD programming of the MindMotion MM32F103CBT6 microcontroller:
| Pin | Function |
|---|---|
| 1 | GND |
| 2 | SWCLK (PA14) |
| 3 | SWDIO (PA13) |
| 4 | VCC |
DC Jack
- center positive
- 7VDC - 12VDC input
RS-232
| DE9 Pin | Wire Color | Function | Direction |
|---|---|---|---|
| 2 | green | RXD | RFID → PC |
| 3 | white | TXD | RFID ← PC |
| 5 | black | GND | RFID ↔ PC |
Flying Leads
| Wire Color | Function | Direction |
|---|---|---|
| black | GND | RFID ↔ PC |
| red | 7 - 12VDC | RFID ← PC |
| green | RS-232 RXD | RFID → PC |
| white | RS-232 TXD | RFID ← PC |
| grey | Wiegand D1 | RFID → PC |
| purple | Wiegand D0 | RFID → PC |
Software
There seems to be variants of two different pieces of "demo" software -- one written in C++ that can interact with the device over USB, and another written in Java.

Protocol
USB
- USB HID device (virtual keyboard)
- VID:PID is
0xffff:0x0035
If configured, it can also show up as a virtual COM port:
- USB CDC device (virtual COM / serial port)
- VID:PID is
0x0483:0x5740
On Windows 7 at least, it requires the ST CDC driver:

On Linux it "just works".
