Function and purpose
The VT485r is an extension PCB board that allows for the connection of readers and keypads that support the OSDP protocol. This board is compatible with Vutlan monitoring systems, including VT335t, VT336t, VT825t, and VT855t. It can be installed while the unit is in operation, providing flexibility and minimizing downtime. The board comes with an internal termination that is switched on by default, which can be turned off if needed.
The VT485r supports various devices such as SE mini reader and other third-party OSDP readers or keypads, making it a versatile tool for integrating access control into Vutlan monitoring systems.

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
Usually, OSDPv2 is back-compatible with OSDPv1 devices. However, each such device needs to be tested.
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.
