Note: The LTS is not plug and play. The format of the strings being received must be known
in advance, including non-printing control characters. If you do not know the string
format, contact tech support of the sending device's manufacturer, or use a terminal
emulator program like HyperTerminal, PuTTY or RealTerm to view the actual trans-
mitted characters.

The Control Inputs pull-down menu controls the effect of grounding Control Input 1, Control
Input 2, or both. Selections applicable to the serial input transmitter are the following:
•
Meter Reset, Function Reset, Meter Reset (first row). When this row is selected,
grounding Control Input 2 causes a function reset, which resets latched alarms.
•
Activate Alarm 1, Activate Alarm 2, Activate Alarm 1&2 . When this row is selected,
grounding Control Input 1 activates relay 1, grounding Control Input 2 activates relay 2, and
grounding both inputs activates Alarms 1 & 2.
•
Tare Enable, Tare if Enabled, Tare (last row). When this row is selected, grounding Control
Input 1 (normally with a permanent connection) enables the Tare function. Momentarily
grounding Control Input 2 stores the current digital value as an offset and subtracts this
offset from the digital reading sent to the transmitter, resulting in a zero value for alarms and
the analog output. This offset will also be subtracted from all new readings sent to the
transmitter. To change the offset, momentarily ground Control Input 2 for the new input.
