Appendix K. RF401/RF411 Pass/Fail Tests
TESTING RF401/RF411s
After verifying the functionality of the terminal program and the integrity of
the serial cable and COM port, proceed as follows:
(1) Connect 12V power to an RF401/RF411 (Field Power Cable (Item #
14291) with 12V battery pack attached (see step 12 below)).
(2) Connect first RF401/RF411’s RS-232 port to the PC COM port
(3) Run a terminal program such as HyperTerminal TM or Procomm TM
(a) Baud rate: 9600
(b) Data, Parity, Stop Bits: 8-N-1
(c) Flow control: none
(d) Emulation: TTY
(e) ASCII
(f) Desired COM port
Make sure that Properties/Settings/ASCII Setup “Echo characters
locally” or the equivalent Procomm TM setting is NOT enabled.
(4) Press “Setup” button on RF401/RF411
(5) Select “3” to restore defaults, then select “5” to save parameters and exit
The presence of a neighboring RF401/RF411 network with default
settings could interfere with your tests.
- RX LED Test -
To determine if there is a neighboring RF401 network in operation
using the same hopping sequence as yours, stop communications on
your network and observe RF401 green LEDs for activity. At this
point, any green LED activity would indicate that there is a nearby
network using the same hopping sequence.
(6) Repeat steps 1 to 5 inclusive with second RF401/RF411
(7) Label the RF401/RF411 connected to the PC COM port as “Base”
(8) Place the two RF401/RF411s side by side with antenna connectors 1 1/8
inches apart on a non-metallic surface (see FIGURE K-1).
