I/O X-Card RS-232 Port
Four pins on the high density DB15 support a 4-wire RS-232 interface. The
interface also supports features like AT, TCP PAD and UDP PAD.
Specification
Note: There is no connection for RI, DCD, DTR or DSR. These are available on the DB-9
serial port. See Serial Port

Dual Ethernet X-Card

This card adds two RJ-45 Ethernet ports to the device for a total of three. The two
Ethernet ports on the X-Card are bridged with the device's main Ethernet port,
automatically becoming part of the same subnet.
The main Ethernet port on the rear panel is a high performance Ethernet port with
data rates up to 100 Mbps.
The Dual Ethernet X-Card provides additional Ethernet ports for applications
requiring lower throughput (in the range of 8–9 Mbps, or less if both ports are
being used).
For example, the Ethernet ports on the Dual Ethernet X-Card are ideal for
applications that run on IP or other protocols that run on top of IP such as TCP
and UDP.
Other suggested applications include:
• Modbus applications
• Low Resolution MMS (MultiMediaStreaming using mms://) applications
• Message Queuing Telemetry Transport (MQTT) applications
• Low Resolution Video surveillance applications
Configuring Dual Ethernet X-Card Ports
When your GX Series device has a Dual Ethernet X-Card installed, you can
configure the additional Ethernet ports as Ethernet 2 and Ethernet 3 on the
ACEmanager LAN > Ethernet screen. Information about the Ethernet ports
