SPRINGFIELD, Mo. — DMP announces that all 734 Series access control modules now support both Wiegand and Open Supervised Device Protocol (OSDP) readers.
OSDP was developed by the Security Industry Association in 2011 and has become one of the most commonly used standards for access control installations. For increased security, OSDP supports high-end 128-bit AES encryption to more effectively prevent the interception of data between modules and readers.
“What this means to you is that someone can’t come in and plug in a laptop or any other device and intercept the communication between the reader and the 734 module,” says Justin Norris, product manager of Access Control. “With OSDP support, our 734, 734N and 734N-POE modules are one of the most secure access control modules available.”
In addition to the selection of Wiegand card readers, all of the Farpointe readers that DMP offers are fully tested and compatible with its OSDP-capable modules. Using Farpointe’s Delta Series OSDP readers, integrators can take advantage of the OSDP protocol along with the MIFARE DESFire credential and the higher security that comes with them, according to the company.
To connect to compatible OSDP readers, DMP access control modules use RS-485, which provides bidirectional two-way communication to acknowledge messages between the reader and module. Also, with standard wiring, it extends the range of data transmission. With the proper RS-485 cable, the range can expand even more, up to 4,000 feet.
DMP also allows customers to create their own alphanumeric secure keys with up to 16 characters. This customized secure key permanently bonds OSDP readers to modules, further protecting access control systems against tampering and reader swapping and giving more customers greater flexibility, according to the company.
“Since DMP’s modules allow users to create their own secure key, this means you can swap out modules as needed without having to swap out the reader and still be able to connect encrypted,” adds Norris.
