5 Transmitting Data
The WI-125 LED provides an RS-232 output for data transmission to a peripheral
device. Refer to the Service Manual for RS-232 interface connections.
5.1 RS-232 Output
To transmit data, follow these instructions:
If your indicator has a peripheral device connected, from the gross/net weighing mode
press the PRINT key to transmit the selected output(s)…
The PRINT annunciator (See Figure 3.1) will illuminate while data is
transmitted and the data configured to be printed will be output to the
printer. See Figure 5.1 for a sample printout.
5.1.1 Communication protocol
Samples of the default printout for a WI-125 LED are shown in Figure 5.1. This is the
displayed weight (Gross or Net) followed by a carriage return and line feed.
An enquire code can be sent to the WI-125 LED. This will prompt the indicator to send
a standard printout. The default enquire code number is an ASCII decimal 005. This
number can be changed in configuration.
