GENERAL DESCRIPTION
Page
The Hand Held Communicator provides a smart
interface with HART electronic transmitters : it is designed
to enable the plant engineer to configure, calibrate and
troubleshoot the transmitters either before or after field
installation.
The Hand Held Communicator can store in its non-volatile
memory up to 32 transmitter configurations.
It can also be used as a Modem between the Personal
Computer and the transmitter.
The Communicator employs a four line by twenty dot-
matrix characters LCD and a 25 key tactile feedback
keyboard : the use of the keyboard is based either on
dedicated keys or software defined keys.
The communication between the Communicator and the
transmitter is based on standard Bell 202 FSK ( Frequen-
cy Shift Keying) current modulation superimposed on the
4 to 20 mA analog signal: since the energy balance
added to the current loop is virtually equal to zero no
disturbance or interference occurs on the analog process
signal.
This version of the Communicator is powered by
internal rechargeable batteries and is certified intrinsi-
cally safe for use in hazardous locations.
