OSDP Readers - Access It! Universal.NET 5.2


Overview

OSDP is a bi-directional protocol that can be used to communicate between devices. When used with readers it has advantages over the typical Wiegand and Clock/Data protocols in that the communication is bi-directional. This allows functionality like clock updates, LCD text updates, and detecting if the device is online.
Functionality for clock and LCD text updates currently exist only on the MR-DT keypad.

Panel Requirements

The following Mercury-Security panels currently support OSDP version 0.9:

  • Series II MR-50
  • Series II MR-52
  • MR-51e
  • EP-1501
    EP-1501+ Reader does not support OSDP.
  • EP-1502
  • MR-DT min f/w 1.63

The following Mercury-Security panels currently support OSDP version 2.1.6 w/ secure channel:

  • Series III MR-52*
  • Series III MR-50*
  • LP-1501*
    LP-1501+ Reader does not support OSDP.
  • LP-1502*
  • LP-4502*
  • MR-51e min f/w 1.59
  • EP-1501 min f/w 1.201
    EP-1501+ Reader does not support OSDP.
  • EP-1502 min f/w 1.201
  • EP-4502 min f/w 1.20.8

*In certain installation environments, OSDP readers are interpreting a non-driven 485-line as data. This interpretation results in a communication fault that is inhibiting the panel and reader from properly communicating. Place a 1K ohm resistor to pull down the Mercury RS485- (D0) to GND line. This will create a communication bias that will keep the reader from improperly interpreting data. To function properly, there must be no ground faults in the installation. Please ensure that the DC Ground (power supply return) is not connected to earth ground.

Reader Requirements

In order to add an OSDP reader to an Access It! Universal.NET system, the reader must support the following:

  • Address selectable between 0 and 3
  • Baud Rate configurable for 9600, 19200, 38400, or 115200
    With Access It! Universal.NET v5.2 only a single OSDP reader is allowed for each reader port. This has changed with Access It! Universal.NET v6.1 and newer. See OSDP IN/OUT Multi-Drop Mode for more information.

Creating OSDP Format

  1. Within Access It! Universal.NET, navigate to the Hardware menu
  2. Within the Hardware Tree, select Installed Readers
  3. Edit the reader that will be using the OSDP Protocol
  4. Select the Reader Settings tab
  5. Select the Edit button next to Reader Type
  6. Select New
  7. Within the Reader Type Name field, enter a friendly name for the OSDP format
  8. Select the Options tab
  9. From the LED mode/protocol list, select the option Enable OSDP driver
  10. Select the baud rate to be used for this OSDP format
  11. Select the reader address for this OSDP format
  12. If encrypted OSDP communication is required, select (check) the Secure channel option
    See Secure Channel Configuration section for more information.
  13. Selecting Enable diagnostic tracing will insert debugging information within the SCP debug text file
    Only to be enabled per the advice of RS2 Technical Support.
  14. Select the Reader LED Function to be used for this OSDP format
  15. Click OK
  16. Click Save

Secure Channel Configuration

Enabling the Secure Channel OSDP setting will encrypt the data communication between the OSDP reader and the SIO reader port. Prior to the following steps, the reader must ready to accept the default key in order to begin using encrypted communication.

Please note that once a reader has been paired to an encrypted reader channel, the reader is married to that specific port for life and will no longer work with any other reader port without first being unpaired. To un-pair a reader RS2 Technical Support needs to be engaged.
Not all OSDP readers support Secure Channel. Consult the reader manufacturer for Secure Channel compatibility.

  1. Within Access It! Universal.NET, navigate to the Hardware menu
  2. Within the Hardware Tree, select Installed Readers
  3. Edit the Reader
  4. Select the Reader settings tab
  5. Ensure the reader type assigned is configured for OSDP Secure Chanel
  6. Click Save
  7. Right click on the reader which requires encrypted OSDP communication
  8. From the command list, select Start Link Mode

Software Configuration

Within Access It! Universal.NET, the following steps must be taken.

  1. Within Access It! Universal.NET, navigate to the Hardware menu
  2. Within the Hardware Tree, select Installed Readers
  3. Edit the reader that will be using the OSDP Protocol
  4. Select the Reader Settings tab
  5. Set the Reader Type to the newly created OSDP format
  6. Click Save
