continuous data format.

RECEIVING THE DATA FOR THE FIRST TIME-
After the power up sequence, the RD-300/RD-232 synchronizes with the incoming serial data line and looks for
data to receive. If no readable data is received within a few seconds, the display shows
nosig
.
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 RD-300/RD-232 displays this information with the appropriate status segments. Some formats do not make
this data available. In this case, the segments are not illuminated.
If you have trouble, remember, you must have continuous data coming from the meter. The most common
problems are non-standard indicator serial outputs, mis-wiring, and mis-programming both in the meter and in
the RD-300/RD-232 setup. Check the LED and see if it is flashing. If it is, then something is being received.
NOTE: This doesn't mean that the format is correct, only that data is appearing at the receiver.
When the display is operating properly, the job is only partially done. Any good installation isn’t finished until
the enclosure mounting is checked and tightened, all conduit and cable entries are wrench tight, and the enclosure
screws have been tightened with a socket or screwdriver.
If the RD-300/RD-232 is located in a wet, damp, or cold environment, it is suggested to use a silica gel desiccant
or better yet, an antioxidant “snowball” made by Hoffman Enclosure Company. These products in the enclosure
will greatly increase product reliability and performance. Change any desiccant at least two times per year.
