Introduction

The 3e-250 Bluetooth to RS-232 Cordless Adapter is a Plug and Play

adapter that allows you to use your RS-232 (serial) port to communicate

wirelessly between multiple pieces of equipment.

In itself, the 3e-250 requires no installation of software or drivers on

the host machine. It doesn't initiate communications, but simply acts as a

substitute for a wired serial connection. As such, it allows direct commu-

nication between equipment such as data recorders, computers, handheld

devices, test electronics equipment, measurement devices and the like.

It enables users to connect measurement devices wirelessly to a cen-

tral analysis and recording area, eliminating the need to download infor-

mation from an unconnected measurement device.

The adapter incorporates a Bluetooth solution containing a BT 1.1

compliant transceiver operating in the 2.4 GHz range using frequency-

hopping at 1600 times/sec among the available frequency ranges.

The operating range of the 3e-250 is up to 30m or 100 feet. It provides

link control functionality and supports operation within a Bluetooth

piconet in a slave mode. It supports all Bluetooth data rates of up to 723

Kbits/sec.
