APPENDIX B. CONTROL PORT SERIAL I/O INSTRUCTION 15
B-10
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)
