Function and purpose
It is an extension PCB board and should be purchased separately.
Allows to connect readers, and keypads with OSDP protocol support.
It can be used with VT335t, VT825t, and VT855t monitoring systems. VT485r can be inserted inside the monitoring unit while the unit is in operation. Has an internal termination and by default, it is switched ON (if required can be turned Off).
Allows to connect SE mini reader, SE keypad, 8CD slim reader, and any other 3rd party OSDP readers or keypads.

Installation of VT485r
This procedure can be done during an operational Vutlan monitoring unit.
Step | Picture | Description |
|---|---|---|
1
| Unscrew the small panel on the monitoring unit using the screw driver. Put the panel aside. | |
2 | Plugin VT485r PCB into the unit so that the PCB will placed between the PCB guide rails.
| |
3 | Take the panel from step 1 and cut off the panel inside it using pliers. | |
4 | Mount the panel back to the unit using the screw driver. |
Activate VT485r
Step | Picture | Description |
|---|---|---|
1 | Open Vutlan web Interface of your system. Go to panel “Preferences” >> tab “OSDP”. If the Extension VT485r is connected, you should see the the element “VT485R OSDP reader board” Tick “Enable OSDP” >> press “Save”. |
Connect readers/keypads to VT485r
You can connect the following OSDPv2 readers/keypads/devices:
Any other 3rd OSDPv2 party reader/keypad/device
We recommend connecting no more than x2 devices/readers powering from VT485r. If you power too many devices, a fuse inside the monitoring unit will activate and it will power down the monitoring system.
Terminate B(-) and A(+) end of the line with a 120 Ohm resistor.
VT485r PCB has 120Ohm resistor termination.
Use only twisted pair cables for B(-) and A(+) conductors.
Add RFID virtual element (e.g. SE mini reader)
To add a reader to the system, we need to create an “RFID reader” virtual element.

What is the OSDPv2 protocol and what are its advantages?
Open Supervised Device Protocol (OSDP) is an access control communications standard developed by the Security Industry Association (SIA) to improve interoperability among access control and security products.
OSDP was approved as an international standard by the International Electrotechnical Commission in May 2020 and has been published as IEC 60839-11-5.
SIA OSDP v2.2, which is based on the IEC 60839-11-5 standard, was released in December 2020. SIA OSDP is in constant refinement to retain its industry-leading position.
Higher Security
OSDP is more secure than the most common access control communications protocol.
OSDP Secure Channel supports high-end AES-128 encryption (required in federal government applications).
OSDP constantly monitors wiring to protect against attack threats.
Advanced Functionality
OSDP supports advanced smartcard technology applications, including PKI/FICAM and biometrics.
OSDP supports bi-directional communications among devices.
OSDP supports an advanced user interface, including welcome messages and text prompts.
OSDP’s use of 2 wires instead of 12+ allows for multi-drop installation, supervised connections to indicate reader malfunctions, and scalability to connect more field devices.
Ease of Use
Audio-visual user feedback mechanisms provide a rich, user-centric access control environment.
Guesswork is eliminated since encryption and authentication are predefined.
Low cost of implementation on an embedded device.
More Interoperability
Using OSDP enables communication among different manufacturers' devices and solutions.
The standard applies to peripheral devices such as card readers and other devices at secured access doors/gates and their control panels.
SIA promotes the standard at regular “plugfests” among manufacturers and at SIA InteropFest– an annual interoperability event held at the ISC West trade show.
The OSDP specification is currently recommended when TCP/IP, USB or other common protocols do not lend themselves to the application.
The OSDP specification is extensible to IP environments and the OSDP Working Group is working on deploying OSDP over IP soon.
