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

or Procomm

(a) Baud rate: 9600

(b) Data, Parity, Stop Bits: 8-N-1

(d) Emulation: TTY

(e) ASCII

(f) Desired COM port

Make sure that Properties/Settings/ASCII Setup “Echo characters

locally” or the equivalent Procomm

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).
