In addition, most applications in a SCADA system require modem port priority. This
allows the QuadraScan software to perform data collections and activations when
necessary. Coordinating QuadraScan activities with SCADA system operation
minimizes real-time data loss and ensures that these activities occur at a non-critical
time.
To ensure the modem port has priority, place the jumper on the two pins closest to the
label “modem”. This will cause the modem to connect with the other modem and set
the DCD when the modem detects a ring, switching the serial multiplexor to the
modem port.
Note:
Refer to the figure on page 5-17 and the table on page 5-18 for options
switch settings used during real time applications.
