U-Prox mini MF
User Manual
Introduction
The U-Prox mini MF reader is intended for use in various access control systems, supporting RS232, Wiegand (26, 32, 34, 37, 40, 42, 56, 58, 64, auto), and TouchMemory interfaces. It supports direct and reverse ID byte order. Personification of mobile and Mifare® identifiers is enabled by setting an additional secure mode. The reader supports two operation modes for smartphones with U-Prox ID:
- "Door" - up to 60-70 cm
- "Barrier/Gate" - adjustable range of interaction from 1 to 15 m.
Identifiers Types
The U-Prox mini MF proximity reader operates with various Mifare® cards, including Mifare® Plus (SL1 and SL3 modes), MIFARE® Standard, MIFARE® Ultralight, MIFARE DESFire, MIFARE CLASSIC 1k, MIFARE Classic 4k, MIFARE CLASSIC 7UID, and/or U-Prox IDs. Reader settings, interface, and identifier types are adjusted via a mobile application, allowing programming for Mifare® and/or U-Prox ID operation.
Design
The reader features an elegant plastic sealed enclosure with IP66 class protection.

Read Range
The typical read range is 50 mm and varies based on the tag type and installation environment.
Wiring
The reader is equipped with an 8-wire cable for connection to the access control panel. The reader terminal functions are detailed in the table below. Integrated Technical Vision Ltd. recommends using a multi-core signal cable with a 0.22 mm² cross-section for each wire between the reader and the panel. The maximum cable distance to the panel is up to 150 m for the Wiegand interface.
Figure 1 Description: This diagram illustrates the reader's terminal connections. The wires are color-coded and mapped to functions:
- Green wire: Data 0 / Rx
- White wire: Data 1 / Tx
- Red wire: +V (Power input)
- Black wire: GND (Ground)
- Brown wire: Red LED control
- Orange wire: Green LED control
- Blue wire: Buzzer control
- Yellow wire: Hold mode control
Additional connections shown are for DB-9 (RS232), Touch Memory, and iButton interfaces.
Types of Interfaces
Depending on the modification, the reader supports one of the following interfaces: Wiegand 26, 32, 34, 37, 40, 42, 56, 58, 64, or standard with automatic selection. It also supports RS-232C (RS), enhanced encrypted RS Pro protocol, or TouchMemory.
Mounting
It is recommended to install the reader on the wall next to the door, from the lock side, in a way that is convenient for all users. Make a small recess or hole (diameter 14 mm) to connect the cable under the reader's case. Avoid placing the reader on metal surfaces, as this can decrease the read range. If multiple readers are used, place them at least 20 cm apart to prevent double reading.
Reader Installation
Follow these steps for installation:
- Loosen the screw at the bottom of the reader.
- Remove the top cover and the back plate.
- Mount the back plate on the wall using the provided fixtures (refer to Figure 2).
- Prepare all wires for connection and connect them to the reader according to Table 1 and the access control panel's user manual.
- Insert the reader into the back plate (refer to Figure 3).
- Attach the top cover and tighten the bottom screw.
- Ensure all locking tabs are securely engaged.

The Reader Operation
RFID Card Code Reading
Code is read when a valid RF ID is passed. Card code reading is annunciated by the embedded buzzer and LED lamp according to the interface type and annunciation mode. Subsequent reading is available after 0.8 seconds once the card is removed from the reader's sensing area.
U-Prox ID Code Reading
Download and install the mobile software U-Prox Mobile ID. This enables receiving, storing U-Prox ID, and transferring ID codes between the reader and a smartphone. Obtain the U-Prox ID identifier from U-Prox Desktop locally, or remotely via email or QR code. Hold the mobile device near the reader (standard distance 10-40 cm) and press the "Open" button in the app. The application will execute data exchange. Card code reading is annunciated by the embedded buzzer and LED according to the interface type and annunciation mode.
Hold Mode
The reader enters hold mode when the yellow wire is shorted to ground. In this mode, the reader does not read cards, reducing current consumption to 25 mA. A relay or an open collector transistor can switch on hold mode. Supplying external voltage to the yellow wire is prohibited.
Data Transfer and Annunciation
The reader has bicolour LED indicators and a buzzer. Their control depends on the interface type. For the Wiegand Interface, LED and buzzer engagement is automatic or by grounding the corresponding wire.
Annunciation Mode Table:
| Mode Code | Buzzer | Red LED | Green LED |
|---|---|---|---|
| 00 | Beep on card read | LED normally on, switch off at reading | Blinking at reading |
| 01 | Control from outside | LED normally on, switch off at reading | Blinking at reading |
| 02 | Beep on card read | Switch off | Blinking at reading |
| 03 | Control from outside | Switch off | Blinking at reading |
| 04 | Beep on card read | LED normally on, switch off at reading | Control from panel |
| 05 | Control from outside | LED normally on, switch off at reading | Control from panel |
| 06 | Beep on card read | Control from panel | Control from panel |
| 07 | Control from outside | Control from panel | Control from panel |
| 08 | Beep on card read; Possibly to control from outside | LED normally on, switch off at reading; Possibly to control from outside | Blinking at reading; Possibly to switch on from outside |
Data transfer from the reader corresponds to the specified standard.
Interface RS232
The reader transmits a packet with the card code after successful RF or U-Prox ID read. The panel must send a control packet to the reader for annunciation control. RS232 settings are 2400 bps rate, 8-bit data, 1 stop bit.
RS232 Packet Format:
| Byte | Bit 7 | Bit 6 | Bit 5 | Bit 4 | Bit 3 | Bit 2 | Bit 1 | Bit 0 |
|---|---|---|---|---|---|---|---|---|
| byte 0 | 0 | 1 | 0 | 0 | 1 | 0 | 0 | 1 |
| byte 1 | - | - | red blinks | - | red on | - | - | - |
| byte 2 | green on | - | green blinks | - | buzzer pulsatory | - | buzzer uninterruptedly |
A '1' corresponds to LED or buzzer switching on. LED blinking and buzzer pulsatory control bits have the highest priority. Annunciation does not change until the next control packet is received.
Reader transmits data as follows:
| Byte # | Data | Checksum | End | |
|---|---|---|---|---|
| Card read | 23h | data | C sum | 0D h |
| PIN entered | 21h | data | C sum | 0D h |
Data Format:
| Bit | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
|---|---|---|---|---|---|---|---|---|
| Format | 0 | 0 | 1 | 1 | X | X | X | X |
Checksum: Exclusive OR of low nibbles of bytes from 1 to 10; the high nibble must always be 3h. Example: Card code 7E000460AA will be sent as: 23h, 37h, 3Eh, 30h, 30h, 30h, 34h, 36h, 30h, 3Ah, 3Ah, 3Bh, 0Dh.
Personalization Mode
In personalization operation mode, the reader transmits code only after a U-Prox ID or Mifare ID encrypted with a valid key is successfully read.
Reader Programming
Download and install the mobile software U-Prox Config for total reader configuration. To run the reader in programming mode, short the D0 (green) and D1 (white) terminals together and power up the reader. An "To access, shorten green and white wires and then restart reader" message appears in the program window if the connection attempt is unauthorized (D0 and D1 terminals are not shorted).
U-Prox Config App Usage:
