Sending the access control result to a distant system
Presentation
After access control rights check, the MorphoAccess® terminal can send a message
which contains the result of the control, to a distant device (such as a Central Security
Controller). The MorphoAccess® terminal is able to use different channels and
different protocols, to send this message.
This message can be used, for instance, to log the access request or to perform
additional access rights check. It depends on the role of the distant device in the global
access control system.

Please refer to MorphoAccess® Remote Messages Specification for more information
about the format and the protocol of the access control result messages.
The LED IN feature enables to expect a positive answer from the distant system before
granting the access.
Available ports and protocols
The MorphoAccess® VP Series terminal is able to send the access control result
messages to a distant system, using the following ports and protocols:
• serial port : Wiegand or DataClock, or RS485
• Ethernet link or Wi-Fi™ link: TCP or UDP or SSL
This is detailed in the next sections.
