5. INTERFACING TO OTHER FEEDS OR DEVICES
In many cases a feed that is not currently supported may have a programmable basic module or other
means of customization. You may also want to tie in a PLC or other controlling device that is handling an
entire feed line. In these cases it makes sense to program the device to emulate (or “look like”) another
already supported feed. The simplest feed to emulate is the Electro-Craft IQ2000 series. The protocol is
as follows:
Communications:
RS232, 9600 baud, no parity, 1 start bit, 1 stop bit, 8 data bits.
Conventions:
[CR] = Carriage return
[LF]
= Line Feed
[S] = Space
X = Digit (0-9)
To Request Length from the feed:
5000 Sends:
G1[CR]
Feed Returns:
G1[CR][LF]G1[S]=[S]XXXX.XXXX[CR][LF][CR][LF]PDM>
To Send Length to feed:
5000 Sends:
G1=XXX.XXX[CR]
Feed Returns:
G1=XXX.XXX[CR][LF]G1[S]=[S]XXXX.XXXX[CR][LF][CR][LF]PDM>
