- 2 wires AWG20 – 164 ft max / 4 wires AWG20 – 328 ft max

Buzzer / LED

The operating mode for the Buzzer and LED 1 and 2 can be programmed by a configuration card (R3x & S3x) or controlled by the remote system with a 0 Vdc respectively on the “Led 1”, “Led 2” and “Buzzer” inputs of the reader’s connector or controlled by the communication protocol of the reader (W3x).

Anti-tearing

Tearing is detected by an accelerometer. When the reader is wrenched, the switch output (connector J2) provides an O/C contact to indicate the tearing of reader.

for R/S 31/x1: the wrenching signal will be emitted on the “Data/Data1” line. This function is configurable via a configuration card.
for R/S 32/33/x2/x3 and OSDPTM: the reader will perform the operations configured with the configuration card.
for W 32/33/x2/x3: the reader will perform the operations configured with the SSCP protocol.

Caution : switch on the reader when it is in its final position to initialize the accelerometer in the correct position.

Relay

Read-only reader: automatic tamper management (except touch screen) or activated on the reading of a valid identifier Touch screen read-only reader: if the bell is activated, contact J2 is used to connect the external ring (max. 200 mA at 28 Vdc). Read/Write & OSDPTM readers: the relay is controlled by the SSCP/ OSDPTM protocol commands.

UHF default configuration settings

Reader powered off. The defaults reader settings can be stored in internal memory accessible by UHF RFID technology. They will be taken into account when the reader is powered on.

Read-only reader configuration

R and S readers are configurable with the SCB configuration card created with SECard. OSDPTM readers are configurable with OCB configuration card:

If the SCB/OCB is compatible with the reader’s firmware, the LED lights green and the buzzer beeps five times.
If the SCB/OCB is not compatible with the reader’s firmware, the LED lights red and the buzzer is activated for 1 s.
If the SCB/OCB key is different from the reader’s key: no reaction.

Caution : set your reader with your own company key.

Powering-up the readers

On power-up, the reader enters an initialization phase:

Activation of the white LED and buzzer for 100 ms. For read-only and OSDPTM readers:
Activation of the LED, according to the color code: Red = +10, Orange = +5, Green = +1, indicating the firmware version.
For serial R/S ARC only: the orange LED flashes 20 times: waiting for an update.
Activation of the default LED (read-only: flashes blue, OSDPTM: off; if no customer specific configuration).
ARC Screen: display of the default image and keypad activation by touching the screen.
For the ARC screen with an activated keypad, the default mode is displaying the picture on standby and activate the keyboard by pressing the screen.

Precautions for the biometric sensor and keypad

For optimal operation, the biometric sensor must be free of all traces of water. Outdoors it is recommended to install the reader under cover.
The keypad is sensitive. Take off your gloves to enter your code.

Precautions for installation

The supply voltage at the reader’s connector should be between +7 Vdc and +28 Vdc.
As far as possible, keep the reader away from computer or power source cables. They can generate electrical interference, depending on their radiation level and the proximity of the reader.
Recommended distance between two readers: parallel plane: 11.8 in – same plane: 15.8 in – perpendicular plane: 9.8 in.
Readers installed on a metal surface may have reduced performances.
Use a ferrite (two-way) for the cable (power supply and data). Example: reference 74271222 WURTH ELEKTRONIK.
By design, the reader can be installed indoors and outdoors.
Connect the wires or the connector of the reader BEFORE powering on.

TTL pull-ups

For data signals, 10k pull-up resistors are connected internally to Vin (power supply voltage) for optimal wiring distances.

RS232 / RS485 communication

*Available Baud rate*	9600, 19200, 38400, 57600, 115200 bauds
*Factory Baud rate*	ARC R & S: 9600; ARC W: 38400 (SSCP), 9600 (OSDPTM

More details about reader communication are available in the protocol specification

Bus architecture (RS485)

Wiring resistors R1 and R2 use extended features of the RS485 bus: FAIL-SAFE (see RS485-AN-960). R1 & R2: 1.5 kΩ resistor supplied. RT: 120 Ω end-of-line resistor supplied

Smart mounting plate dimensions

Scalability

Scalability is a specific feature of the Architect® series. Each reader is composed of three parts: one switchable cover, one RFID core and one smart mounting plate. You can upgrade functionalities and security levels by switching the cover and/or adding a biometric, 125kHz or QR Code module.

Steps to remove the core from the front cover

Procedure to install the core into the front part

Place the core between the two slots at the top of the cover.
And then pivot the core and press to insert it between the two clips.

Procedure to change the front part

Disconnect the flat flexible antenna cable from connector J6.
Remove the core from the front part (steps 1, 2).
Install the core in the keyboard front part.
Connect the flat flexible antenna cable to connector J6 and the flat flexible keyboard cable to connector J7.
Disconnect the flat flexible antenna cable of connector J6.
Remove the core from the front part (steps 1, 2).
Install the core in the screen front part.
Connect the flat flexible antenna cable to connector J6 and the screen ribbon to connector J14.
Disconnect the flat flexible antenna cable from connector J6 and the flat flexible keyboard cable from connector J7.
Remove the core from the front part (steps 1, 2).
Install the core in the screen front part.
Connect the flat flexible antenna cable to connector J6 and the flat flexible screen cable to connector J14.

Mounting

Pass the cables through the hole in the base.
Screw the base in its final location.
Connect the reader.
Test the readings and communication.
Place the reader on the base (clip the top part and then pivot it down).
Lock the reader with the two screws provided using the specific tool.

Procedure to add the biometric (SE6) or 125 kHz module (SE8 / SE8M) or QR Code module (SE9)

STid guarantees the good working order, compliance, technical support and after-sales service of the readers and modules (SE6, SE8, SE8M and SE9) that are installed as explained below, without any internal or external modifications.

Check that the cable length that comes out of the module does not exceed 0.39 in. If it does, push the excess cable into the module housing.
Connect the cable of the module to connector J9. You should not have a loop(1).
Insert the module into the reader slot (until you hear a “click” for SE6)
Cut the base as shown in the drawing(2).
Place the “reader + module” on the base (i.e. Mounting), use the 2 screws provided with the module(3).
Read only readers: Activate the module with configuration card (SCB or OCB).
