Remote Digital Communications RS-485 Terminals 7 & 8 (Optional)
If the communications network continues on to other units, connect the shields together, but
not to the instrument. A terminating resistor should be installed at the terminals of the last
instrument in the loop. The shield should be grounded at the computer or the convertor box, if
used. See the Protocol Manual (Form 2878) for more details on the use of the digital
communications option.
Terminals 7 & 8 are used
for communications when
the model number is
6XXYX3X or 6XXYX5X
where X= any valid number
and Y=0, 1, or 2.
