XLINK 500/100 Operations & Maintenance Manual page # 37
Setup a measurement for stage, type to match the sensor you are using
Setup a measurement to control the sampler, type: Meta.
Set the Index to point to the stage measurement
Set the equation to: OUTPUT(X>12.5,2,1,1000) for DOUT#1, PULSE, 1000 ms.
4.23. Connecting to the Switched Power
A switched power connection SWD#1 is provided. The connection will provide up to 1A of the
input power. The setup and software control when the switched power lines are turned on and
off.
Turned on during each measurement of Analog/Digital/SDI sensor. Warmup can
increase the on time.
4.24. Connecting Protected Power
The protected power is labeled PROT+12V. This power provides 1A of the main power. This can
be used for sensors or equipment that needs to remain powered always. It can be turned
on/off/pulsed via the equation OUTPUT function and via the POWER command.
Only certain models provide this connection.
4.25. Connecting External Modems
You can connect an external modem and use it for remote communications via LinkComm or
other communication programs. The modem must be Sutron’s 8080-0005-1B modem with a
special configuration saved in its profile. The modem will connect to the RS-232 port via a male-
male null modem cable.
Here are the details of how the modem must be configured.
The following table summarizes the AT commands that will be issued:
modem asserts DSR when connection established
enable RTS/CTS hardware flow control
auto answer on first ring
disable +++ escape (allows binary file transmission)
save the settings to nonvolatile memory of the modem
Connect to the modem with HyperTerminal (or similar) using a PC. For the best performance,
connect at 115200, N, 8, 1. The modem remembers the baud rate at the time of the AT&W, so
be sure to communicate at the rate you intend to use with XLink. 115200 baud is the default
rate, but smart modems can go quite a bit faster.
Here's how to configure a modem (assuming it's at factory defaults):
Enter AT and then press ENTER until the modem responds with 'OK'
