Transceiver
Features
The transceiver’s design makes the installation and configuration easy,
while allowing for changes in the future.
• Long Range—Up to 30 miles (48 km) nominal range in
line-of-sight conditions. Repeater stations may be used to
extend the operational range. (Refer to TECHNICAL SPECIFI-
CATIONS on Page 156 for more detailed information on
range.)
• Industrial-Grade Product—Extended temperature range for
trouble-free operation in extreme environments
• Robust Radio Communications—Designed to operate in dense,
high-interference environments
• Robust Network Security—Prevents common attack schemes
and hardware from gaining access or control of network. Com-
mon attack events logged and reported by alarms.
• High Speed—1 Mbps (iNET-II) is 100-times faster than 9.6
kbps radios. GE MDS iNET transceiver speed is 512 kbps.
• Plug-and-Play Connectivity—Ethernet bridge configuration
option requires minimal setup
• Serial Ports—Gateway for serial-based equipment to IP/Ether-
net networks with embedded terminal server. Site-to-site con-
figurations are also possible.
• Single hardware package provides configuration as Access
Point or Remote
1.2.1 Model Offerings
The transceiver comes in two primary models—Access Point and
Remote. Three types of Remote Gateways are available—the Ethernet
Bridge, the Serial Gateway, and the Dual Gateway supporting both
IP/Ethernet and serial services. Table 1-1 summarizes the different
interface abilities for each type.
A unit can be configured by the owner to operate as an Access Point or
as a Remote with some restrictions. Only the Dual Gateway Remote
units can be reconfigured as an Access Point. Ethernet Bridge and a
Serial Gateway Remotes cannot be reconfigured as an Access Point
unless they are first upgraded to Dual Gateway type. This is accom-
plished with an “Authorization Key” purchased from the factory. Each
one of these individual software keys is associated with the serial
number of the corresponding unit.
