U-Prox-mini proximity reader
User manual
Introduction
The proximity reader U-Prox-mini is intended to be applied in
different access control systems, using RS232, Wiegand 26,
Wiegand 37, Wiegand 42, Wiegand auto and Touch Memory
interface.
The interface type is to be changed by special PC program. If you
need to change the interface type please call your distributor.
The reader is placed in elegant plastic case with two color LED
indicator on front panel.
Types of cards
Integrated Technical Vision ltd manufactures readers operating with
amplitude modulation (ASK) and/or frequency modulation (FSK)
proximity cards and tags.

When you connect the reader to the
interface TouchMemory (iButton), and it
does not work consistently (for example,
does not transmit the code identifier
controller), you should use 4,7kOm
resistor (supplied) installed between the
terminal and iButton "Earth" reader, as
shown in Fig. 1.
When using twisted pair (STP, UTP, FTP) to connect the reader should be followed the
order of connection shown in Fig. 2.

Type of interfaces
The proximity reader is intended to apply in different access control systems, using
RS232, Wiegand 26, Wiegand 37, Wiegand 42, Wiegand auto and Touch Memory
interface.
Mounting
It is recommended to mount the reader on a wall closely to a door at appropriate height.
Do not place the reader on the metal surfaces, since it causes decreasing of reading
distance.
If more than one reader is used in the system, place them not closer than 20 cm one
from another to eliminate the effect of doublereading
If impossible to place readers at a distance more than 20 cm one from another it is
allowed to place readers at a distance not less than 10 cm when their yellow wires are
interconnected.
In this operating mode readers work synchronously and alternately.
Using this operating mode is not recommended when set automatic recognition type
of proximity identifier (ASK/FSK).
Reader installation
Loosen the screw at the bottom of the reader.
Remove the top cover, remove the back plate.
Mount the back plate of reader on the wall
using the fixturing provided (see fig. 3).
Prepare all wires for connection and connect
them to the reader in according to Table 1 and
User Manual of the access control panel to be
utilized.
Insert the reader in the back plate (see fig. 4).
Put the top cover and tighten screw at the
bottom of the reader.
Ensure that all locking tabs are securely
engaged.

The Reader Operation
The RFID Card Code Reading
The card code reading is annunciated by built-in buzzer and LED lamp according to
interface type and annunciation mode (see Section «Data transfer and Annunciation»).
Repeated reading will be available after 0.75 sec if the card is removed from the reader
sensing area.
Hold Mode
Reader is turned to the hold mode while yellow wire is closed to ground. In this mode
reader does not read cards, thus current consumption decreases.
Do not apply voltage to yellow wire!
Data transfer and control of annunciation
The reader is provided with two-colour LED indicators and buzzer. LED and buzzer
function according to interface type programmed and annunciation mode.
Wiegand Interface
Engaging of LED and buzzer is possible automatically or by grounding of corresponding
wire according to Table 2.
Table 2. Annunciation mode:
Data transmissions from reader comply with standard Wiegand26, Wiegand37,
Wiegand42 and Wiegand auto.

Interface RS232
To control annunciation send control packet to the reader. Packets should be
transmitted with 2 400 baud rate, 8 bit data, no parity, 1 stop bit.
