5.2.2.6.
6. Operation
6.1. Wiegand Mode
6.1.1. The Wiegand data stream to the control panel is automatic, data will be present
after a card is read, and in the case of the 26-bit Wiegand keypad, data will be sent
by the keypad, on “#” press. If an incorrect pin on the keypad is entered, it may
be cleared by pressing “*”, or letting the keypad time out, a single beep, after 10
seconds of inactivity. In the case of the 8-bit keypad is installed, data will be sent
with each keypress.
6.1.2. The LED & beeper controls are asserted when those lines are connected to the
reader circuit ground, the black wire from the reader, or –Vin.
6.1.3. The reader data contains the CSN, or, if enabled, the card data contents.
6.1.4. If the keypad is configured for 26 bit Wiegand output, the keypad data contains
the programmed site or facility code, plus the entered pin number. There are 255
different site codes, & 65535 different pins possible. If the entered pin is greater
than 65535, this will result in all 1s being transferred in place of the pin, (the site
code will remain the same).
6.1.5. If the keypad is configured for 8 bit it will output 8 bit binary data with each
keystroke, the LSB to bit 3 will be the binary number of the key pressed, bits 4 to
MSB will be the complement of that number. If the “*” key is pressed, the data
will be 0x5A & for the “#” key, the data will be 0x4B.
6.1.6. The keypad & reader data conform to the Wiegand open standard H10301, for
timing and format.
6.2. OSDP Mode
6.2.1. The OSDP (Open Supervised Device Protocol) format conforms to version 2.1.5,
as provided by a third party converter module.
6.2.2. The RS-485 bus may be connected to other devices, in a daisy chain. This bus
may be terminated at the reader with a load resistor, see paragraph 4.4 above to
the location of the jumper that will do this.
6.2.3. Communication with the OSDP adapter;
6.2.3.1. Communication speed with this adapter may be changed using the
“osdp_COMSET” command.
