TABLE B-2. CR10X/Barometer Connection Details

CAUTION:

To avoid damage to the

barometer CMOS chips, connect ground
first and power last. All sensor leads not
used in a particular hook-up configuration
should be insulated to avoid possible
shorting.

B.6.1.3 INSTRUCTION 15 PARAMETER
CONSIDERATIONS

The AIR Barometer requires only the CR10X's
RTS/DTR connected to its shut down or DTR line
to transfer data. No CTS or output is required. It
therefore uses 2 CR10X ports, as described by
"CONFIGURATION 1" (Section B4).

If one AIR barometer is connected according to
Hook-up #1 with only one sample output, the
parameters are as follows:

01:

1

Repetitions

02:

00

Configuration code of
ASCII/TTL/1200 baud

03:

0

CTS/Delay before send (does
not matter)

04: AB

Control ports, (User’s choice)
A to sensor Shut Down.
B to RXD.

05:

0

Output start location (no output
from CR10X)

06:

0

Number of locations to send
(no output from CR10X)
