OSDP
|
||
|
|
####
|
||
|
|
|
||
|
|
OSDP describes the communication interface one or more Peripheral Devices (PD)
|
||
|
|
to a Control Panel (CP). The specification describes the protocol
|
||
|
|
implementation over a two-wire RS-485 multi-drop serial communication channel.
|
||
|
|
Nevertheless, this protocol can be used to transfer secure byte stream over any
|
||
|
|
physical channel in low memory embedded devices.
|
||
|
|
|
||
|
|
Although OSDP is steered towards the Access and Security industries, it can be
|
||
|
|
used as a general communication protocol for devices in a secure way without
|
||
|
|
too much resource requirements. The security is not top-notch (AES-128) but it
|
||
|
|
is reasonable enough, given that the alternative is no security at all.
|
||
|
|
|
||
|
|
OSDP Supports the control of the following components on a PD:
|
||
|
|
- LED
|
||
|
|
- Buzzer
|
||
|
|
- Keypad
|
||
|
|
- Output (GPIOs)
|
||
|
|
- Input Control (GPIOs)
|
||
|
|
- Displays
|
||
|
|
- Device status (tamper, power, etc.,)
|
||
|
