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.
