Model 691HT Communicator may be
connected at any wiring termination
point in the loop, providing the minimum
resistance is 250 ohm.
If this is less than 250 ohm, additional
resistance should be added to allow
communications.

WARNING : DO NOT ATTEMPT TO CONNECT
AN AMMETER BETWEEN A "TEST" TERMINAL AND
A "COMM" TERMINAL. THE RESULT TO THE POWER
SUPPLY IS A SHORT WHICH WILL BLOW FUSES
AND POSSIBLY DAMAGE YOUR EQUIPMENT, ALSO
CAUSING TO INTERRUPT FUNCTION OF OTHER
DEVICES POWERED FROM SAME SUPPLY.
NOTE : If the use of the Hand Held Communicator
is foreseen, resistance of 250 ohms minimum must be
included in the current loop, between the power supply
and the connection point of the Hand Held Terminal for
communication purpose.
