With Secure Open Supervised Device Protocol (OSDP), you can move away from Wiegand readers without making a large infrastructure investment, because only the readers need to be replaced.
The following OSDP readers were certified and are supported by Synergis™ Softwire 11.1. Certified readers were tested for use with random-key encrypted communication. Other OSDP-compliant readers are supported by design.
Supported Synergis™ appliances
OSDP readers connect directly to the RS-485 ports on a Synergis™ Cloud Link or a Synergis™ Master Controller equipped with an RS-485 board.
Streamvault™ appliances are not equipped with RS-485 ports, and are therefore not compatible with direct OSDP readers.
Wiring instructions for STid readers
To enable the extended features of the RS-485 bus, physically place 1.5k Ohm resistors (R1 and R2) on the GND and Vcc connectors of the reader. These 1.5k Ohm resistors do not come with the STid units.
