Appendix J. Monitor CSAT3 via RF401 Series
(g) RS-232 Baud Rate – use the default (9600) for RF401 radios
with OS3 or earlier. For RF401 radios with OS4 or higher,
change the setting to 9600.
(5) Repeat steps 1 - 4 with the “remote” RF401. Temporarily use 6 ft.
cable and AC adapter during the remote RF401 setup. CSAT3
monitoring requires a Point-to-Point network so you should configure
all remote RF401 settings the same as you did for the base RF401.
CSAT3 SETUP
(1) Power CSAT3 off and then back on
(2) Connect CSAT3’s RS-232 cable to the desired PC COM port
(3) Run CSAT32 software
(4) Select correct COM port if necessary under Settings\Communication
(5) Enter Terminal mode (bottom tab)
(6) Open Port (if not already open)
(7) Press [Enter] a couple of times to get “>“ prompt
(8) Enter “br 0” and press [Enter] to send it to CSAT3 to configure RS-
232 communications to 9600 baud.
(9) Enter “ri 1” and press [Enter] to send it to CSAT3 to turn on RS-232
drivers (if you want to save this setting in non-volatile RAM, refer to
CSAT3 Instruction Manual, Appendix B).
(10) Return to Data mode (bottom tab)
HARDWARE SETUP
(1) Base station
(a) Plug AC adapter into 120 VAC outlet and barrel connector into
“Power” jack on base RF401.
(b) Connect 6 ft. cable (from base kit) between PC COM port of
choice and RF401 RS-232 port.
(2) Remote station
(a) Connect 12 V power supply to RF401 (can be either 120V AC
adapter or 12V Field Power Cable)
(b) Connect 9 pin male to 9 pin male null-modem cable from
CSAT3 RS-232 connector to RF401’s RS-232 connector.
(c) You are ready to start taking measurements
TROUBLESHOOTING
(1) If your readings appear off-scale, try closing CSAT32 and running it
again.
(2) If not communicating with anemometer, make sure RS-232 driver is
turned on (see CSAT3 SETUP).
