Configuring the IP Address
The MP9320 is equipped with an optional TCP/IP Ethernet port and embedded IP
device server. This reader is configured for automatic IP address allocation using the
Dynamic Host Configuration Protocol (DHCP) Mode and the reader automatically
extracts the IP address from the DHCP server. This is the default mode for the reader
as it is shipped from the factory.
Digital (TTL) Input/Output Setup
The MP9320 is equipped with a digital I/O port that provides four logic-level (TTL)
input signals and four output signals. Refer to the SAMSys Forth Programming
Language Reference Guide for programming information. The digital inputs are
optically isolated. The outputs are open collector.
