and RS-485. RS-485 configuration allows operation as an individual data-col-
lection "node" within a computer-controlled network. NOTE: RS-485 conver-
sion is required at the computer's I/O port.
Logic Inputs and Outputs: TTL- and CMOS-compatible; isolated (±1500 V) from
power and communication ports. Negative-true outputs for limit monitoring
(isolated +5 V provides up to 50 mA for driving external devices directly); nega-
tive-true inputs for control of PRINT, TARE, PEAK, and UNLATCH functions.
Inputs*: Logic Volts Without Instru-
