The Access200 comes standard with Wiegand output, or optional OSDP output. For devices originally purchased with Wiegand output, Princeton Identity offers an OSDP field upgrade kit.

For the upgrade it is recommended that the wall plate be removed from the wall and placed on a table. Attempting to upgrade the device while the wall plate is still mounted to the wall is not recommended and may result in the loss of critical spacers.

1. Remove the security screws from the A200 and place the front half of the unit to the side

After removing the screws, the device can be gently pushed up to unseat it from the wall plate. Take care when removing the front half of the unit as there is an ethernet cable connected and a cable connecting the two halves of the unit. Remove the ethernet cable and the cable connecting the front and back half of the unit and place the front to the side.

2. Remove the wall plate from the wall

For the upgrade it is recommended that the wall plate be removed from the wall and placed on a table. Attempting to upgrade the device while the wall plate is still mounted to the wall is not recommended and may result in the loss of critical spacers.

3. Remove the 4 screws form the small IO board

The wall plate is made up of 2 boards: a large board that spans the width of the plate, and a smaller board on the right side. Remove the 4 screws that are connecting the smaller board to the larger board.

Note: there are 4 spacers between the 2 boards that will be used in a later step. Take care to not lose them during the removal process.

4. Gently remove the smaller board from the larger board

Gently lift the smaller board away from the larger board. There are small pins that could be damaged if this step is done too quickly or carelessly.

Place the smaller board and the spacers safely to the side.

5. Place the OSDP board on the large board, then the larger spacers between the 2 boards

The upgrade kit includes 4 taller spacers and a PCB board. Place the OSDP board gently on to the large board. The OSDP board will need to be correctly placed such that all of the pins are aligned with the appropriate holes. Firmly press down on the board to allow the pins to contact one another.

Place the tall spacers between the large board and OSDP board such that they align with the 4 screw holes. The board may need to be lifted slightly to place the spacers below it. The Allen wrench can be used to help align the spacers to the holes.

6. Place the shorter spacers on the screw holes

Place the shorter spacers (from step 3 or 4) on the screw holes of the OSDP adaptor board.

7. Place the smaller IO board on the OSDP adaptor board.

Place the smaller IO board from step 4 gently on to the OSDP adaptor board. The smaller IO board will need to be correctly placed such that all of the pins are aligned with the appropriate holes. Firmly press down on the board to allow the pins to contact one another. If any of the spacers are moved, realign them back to the appropriate holes.

8. Screw in the 4 screws

4 longer screws are included in the upgrade kit. Place these in the 4 holes, ensuring that the spacers remain in place and surround the screw holes. Use the included Allen wrench to screw the screws in. The screws should be hand tight and should not be over tightened.

9. Place the wall plate back on the wall and the front half of the unit back on to the wall plate

With the wall plate completed and mounted back on the wall, reconnect the cable connecting the front half of the unit and the wall plate. Attach the ethernet cable to the device, and place the front half of the unit back on the wall plate. Gently press down on the front half of the unit to secure it to the wall plate. Screw the security screws back in.

The upgrade is complete!

Wiring the A200 with OSDP

After the upgrade is complete the OSDP RS-485 wires will be wired to D0 OUT and D1 OUT on the same PANEL terminal block where Wiegand was previously output. The mapping is below:
