Rice Lake RD-300 Remote Display - Manual (Page 9)

Installation 7
Example:
P210.02 - Sets custom transmit 1 to continuous
P211.01 - Sets custom transmit 1 to send through the printer port
Send a custom transmit. Set for continuous transmission mode and the port selected.
Set up custom transmit 1:
1000ASCII - 02
1001DISPLAY DATA - 98
1002STATUS DATA - 97
1003ASCII - 03
The serial data is as follows:
<02><8 WEIGHT BYTES >< SP >< LB OR KG >< SP ><G ROSS OR N ET SP SP ><S TAT >< SP ><M OR O OR SP ><03>
• Sartorius Balances with RS-232 data output - RS-232 is supported. Set for space parity, 1 stop bit, auto
output print without stability, no ID code, and software handshake. The output data must use the 16
character format.
• Hardy 2151 - Configure the standard serial port for RS-232. You must hardware jumper the RTS to the
CTS pins even if the software handshake is enabled. Select the baud rate and eight data bits with no
parity. To send the gross weight continuously, program
G - - - - - into the output parameter value. To
send the net weight continuously, program - N - - - - into the output parameter value.
• Universal Data Receiver - This receiver can receive serial data in a wide variety of intuitive formats. It
can be used in either RS-232 or current loop. Use when all else fails. This receiver keys on carriage
returns (CR), end of text (ETX), or end of transmission (EOT) characters in the data string. The receiver
looks for G, g, N, n, K, k, L, l, (-) characters and reconstructs the data string from this information.
When the RD-300/RD-232 senses that the universal receiver has been selected, use switch SW2-6 to tell
the unit if the serial string contains a kilogram sign as a K or a KG. The universal receiver always looks
at the data string from back to front. This keeps the receiver from confusing the “g” in kg with a g for
gross mode. If the string uses a single character for kilograms, SW2-6 should be OFF.
• Other Indicators... Many indicators have programmable serial outputs and can be programmed to work
with the RD-300/RD-232, if , and only if, the output formatting exactly matches what the display has
been programmed to accept. If a computer or terminal is going to be used with an RD-300/RD-232, the
universal format is probably the easiest to use if the data is sent continuously. Several other meters have
been interfaced for use with the RD-300/RD-232. Consult the factory for special application needs.
• Choices- Some meters have multiple outputs. Some can have two or more RS-232 outputs or current
loop outputs which can be active or passive. The preferred interface is an active current loop from the
meter. RS-232 is always the least desirable because the ground planes of the two devices must be tied
together. The output data must be continuous. Demand ports are mostly unusable unless the meter uses
the universal, Condec, Fairbanks, or Cardinal formats. If a demand format must be used or the display
must show the last data transmitted, SW2-4 can be used to disable display timeout. Turn SW2-4 ON to
disable display timeout.
*IQ plus 310 has multiple data formats and can be used with multiple receivers
