Serial ASCII data can be output through the controller's interro-
gator port. The output frequency is user-selectable: every 15
seconds, every minute, every 5 minutes, every 15 minutes, or by
command.
To receive serial data as a periodic output:
1. Select YES at screen asking if you want periodic serial out-
put.
2. Select the appropriate baud rate setting in screen . Note
that at all baud rates the data is sent with no parity, eight
data bits, and one stop bit. If you have difficulty with the
connection, try a slower baud rate.
3. Select the desired output interval in screen.
4. Connect to the 6712 controller's interrogator connector
using a standard interrogator cable.
To receive serial data by command:
1. Select NO at the screen asking for periodic serial output .
2. Connect your computer to the 6712 controller's interroga-
tor connector with a standard interrogator cable, P/N
60-2544-040 (25 pin) or 60-2544-044 (9 pin).
3. Configure your communications software for a baud rate
no higher than 19,200 kb, no parity, 8 data bits, and 1 stop
bit.
4. From the computer's keyboard, type "?" repeatedly until
the 6712 controller determines the baud rate. Once the
baud rate is known, the 6712 returns an identification ban-
ner. This banner indicates that the connection is working
properly.
5. Type DATA<CR> each time the data string is desired.
The serial data is in comma-separated-value format. Only the
values that the sampler is set up to measure will be output in the
data string. The string is terminated with a <CR><LF>. To read
the data in the string, refer to Table 5-5. This serial data can also
be accessed from a remote location using the optional dial-out
modem (see Section 7).
Note
The internal modem is disabled when an interrogator cable is
connected to the sampler's Interrogator port. It cannot receive
incoming calls, and the alarm dialout is rendered inoperative,
while this cable is connected. Disconnect the interrogator
cable in order to use the 4200T modem.
