Wi-Fi X-Card

This card adds Wi-Fi capacity to the gateway using the 802.11b/g/n standard. It
has the following modes:
• Client Mode where a GX gateway uses a Wi-Fi client connection to connect to
an access point, rather than acting as an access point (AP)
• Access Point Mode where the gateway acts as an AP
• Both (AP + Client Mode) where the gateway can act as an AP and also use a
Wi-Fi Client connection to connect to an AP
The GX Series gateway connects as a client to a configured AP whenever the
AP is available. When the AP is not available, it connects to a 3G network and
acts as an AP to W-Fi clients connected to the GX.
Note: The Wi-Fi X-card requires the use of an antenna with a male RP-SMA connector.
See the ALEOS Software Configuration User Guide for details on Wi-Fi
configuration and use.

I/O X-Card

This card uses a 15-pin connector to add to the basic gateway:
• One additional RS-232 communication port
• Four additional digital I/O pins
• Four analog voltage sensing pins
• Optional 2 meter I/O X-Card breakout cable (To order, contact your
distributor.)
Maximum data rate for the RS-232 interface on the I/O X-Card is 115.2 kbps.
See the ALEOS Software Configuration User Guide for details on I/O set up and
use.
