Wiegand protocol
The Wiegand frame includes only the user identifier (which must be a numeric value).
By default, the access control result message is sent only when the user is identified or
authenticated.
But as an option this access control result message can be sent when the access is
denied, but with a numeric error code instead of the user identifier value.
The sending of the message through the serial port, using DataClock protocol is
conditioned only one configuration keys.
Send access control result message using Wiegand protocol on serial output port
app/send ID wiegand/enabled = 1
Enabled
app/send ID wiegand/enabled = 0
Disabled
The format of the Wiegand frame is defined by several configuration keys.
DataClock protocol
Same comment as for Wiegand protocol.
The sending of the message through the serial port, using DataClock protocol is
conditioned only one configuration keys.
Send access control result message using DataClock protocol on serial output
port
app/send ID dataclock /enabled = 1
Enabled
app/send ID dataclock /enabled = 0
Disabled
RS485 protocol
The message is send whatever is the control result, and it contains more information
than the Wiegand and the DataClock frames.
The message format (ASCII characters) includes the user identifier, but also the result
of the control, the date and time of the access request, and other data.
The sending of the message through the serial port, using RS484 protocol is
conditioned to two configuration keys.
Send access control result message using RS485 protocol on serial output port
app/send ID serial /enabled = 1
Enabled
app/send ID serial /enabled = 0
Disabled
app/send ID serial/mode = 485
