20 EL232 XCPD Installation Manual
4.6 Receiving Data for the First Time
After the power up sequence, the EL232 XPCD synchronizes with the incoming serial data line and looks for
data to receive. If no readable data is received within a few seconds, the
NO SIG LED in the upper right of the
display is lit and the display shows, “ - - - - - - ”. This LED is also lit if transmission should stop for more than 8-10
seconds during normal operation.
SW1-7 selects the data displayed during a loss of signal state (Section 3.3.1). If SW1-07 is open, the last value
received is displayed continuously. If this switch is closed, the display again shows, “
- - - - - - ” until readable data
is again received. This can be used to alert the operator that data on the display may not be valid. When the data
returns to normal, the display updats and the
NO SIG lamp goes out.
When communication is established, the current weight value is displayed. Decimal points are inserted into the
display as indicated by the meter. If the data format from the meter makes LB, Kg, Gross or Net status available,
the EL232 XPCD displays this information with the appropriate LED status lamps. Some formats do not make
this data available. In this case, the LEDs will not be illuminated.
