Presentation of Proxy (or slave) mode
Process
The administrator can configure the MorphoAccess® SIGMA Family terminal in the proxy mode.
This operating mode allows controlling the MorphoAccess® SIGMA Family terminal remotely via
IP link or RS422 (Applicable to MorphoAccess® SIGMA Series only). This is achieved by using a
set of biometric and databases management commands.
In Proxy mode the Host System plays the master. It performs access control remotely, while the
MorphoAccess® SIGMA Family terminal works as a slave waiting for external commands. These
commands are enlisted as follows.
user identification,
user verification,
relay activation,
read data on a contactless smart card,
Biometric database management,
terminal configuration changes,
read an entry from the keyboard,
display a message,
read a contactless smart card.
The MorphoAccess® SIGMA Family terminal is driven through an Ethernet (or Wi-Fi™) link using
TCP or SSL protocol.
The terminal acts as a server: it is either waiting for a command or executing a command.
Please refer to MorphoAccess® 5G Series – Host System Interface Specifications: this
document explains how to remotely manage a terminal.
