I.1 FORMATTING BAUD RATE
The Setra Digital Pressure Gauge is capable of interfacing with a wide variety of
computers or other devices through the RS-232 serial communications port.
Devices which are connected this way must be set up to communicate at the
same rate of speed.
To change the baud rate of the gauge (the rate at which the gauge sends infor-
mation out through the port) so it agrees with that of the device connected to it,
use the following procedure.
1. Press CONV until the gauge is displaying pressure units (make sure it is not
displaying in "ft" or "meters").
2. Press the "-" key.
3. Enter "5555". This is the baud rate access code.
4. Press SETUP. The display will read "CAL br".
5. Enter the baud rate. Choose either 300, 600, 1200, 1800, 2400, 3600, 4800
or 9600.
6. Press SETUP.
The baud rate is factory set to 2400. If you change the baud rate and wish the
gauge to retain the new rate after power is removed and restored, repeat steps
2-6 a second time.
