1. Introduction
Congratulations on your purchase of the RangeLAN2 791x
Serial Adapter, the radio module that replaces RS-232 serial
cables with wireless RF (Radio Frequency) technology. By
attaching a pair of RangeLAN2 Serial Adapters to the serial port
of any two devices, you can transmit and receive data without
the use of wires.
The RangeLAN2 791x can support several data rates and uses
the same patented 2.4 GHz frequency hopping spread spectrum
(FHSS) technology as found within Proxim’s award-winning
RangeLAN2 product line. The Serial Adapter is designed to
work with numerous off-the-shelf applications as well as with
custom programs. The RangeLAN2 791x may leverage off of an
existing RangeLAN2 network, allowing two Serial Adapters to
communicate over greater distances.
The Serial Adapter is designed to be a “plug and play” product.
External rotary switches allow you to configure your Serial
Adapter manually so that in many cases, you will be able to use
a Serial Adapter without running any software to configure it.
However, the Serial Adapter supports a wide variety of configu-
rations that can be easily changed to fit your application require-
ments. All configuration information is stored in non-volatile
memory called EEPROM (electronically erasable programmable
read-only memory).
Proxim is the leading supplier of spread spectrum radio network-
ing technology for local area environments. Proxim’s un-
matched spread spectrum networking expertise, combined with
the company’s extensive experience serving the communication
needs of the mobile computing user, has kept Proxim at the
forefront of the emerging wireless market.

The RangeLAN2 Family
RangeLAN2 791x Serial Adapter is part of a family of high-
performance products that provides a complete wireless net-
working solution.
❑RangeLAN2 7100 is a wireless LAN adapter that fits
into a standard PC/AT ISA bus slot.
❑RangeLAN2 7400 is a wireless LAN adapter which fits
into a PCMCIA Type II slot on a portable notebook,
laptop, or pen-based computer.
❑RangeLAN2 7510/752x Access Points allow
RangeLAN2 products to seamlessly connect to a wired
Ethernet network.
❑RangeLAN2 753x Access Points allow RangeLAN2
products to seamlessly connect to a wired Token Ring
network.
❑RangeLAN2 754x Extension Point extends the cover-
age area of an existing RangeLAN2 network.
❑There are two models of the RangeLAN2 Serial
Adapter, the 7910 and 7911. The 7910 has 100 mW of
output power, while the 7911 has 500 mW of output
power.
❑RangeLAN2 792x Ethernet Adapter converts any
Ethernet-ready device into a wireless node on an exist-
ing RangeLAN2 network.
