Appendix K. RF401/RF411 Pass/Fail

Tests

This appendix describes a method to functionally test RF401/RF411 system

components including:

• PC COM port

• SC12 serial cable

• RF401/RF411

• RF401/RF411 Antenna

Hardware/Software Required

9 PC with one available COM port

9 Terminal Program (HyperTerminal

or Procomm

)

9 Two RF401/RF411s

9 Two SC12 serial cables

9 ¼ wave OMNI antenna (CSI Item # 14310)

9 Two power supplies rated 12 Volts, 1 Amp

(recommend AC adapter Item # 15966 and any 12 V battery pack with

Field Power Cable Item # 14291)

The following descriptions tell how to build an RF401/RF411 loop-back test

system. Recommendations are given as to where to place the system to avoid

rf-reflections (see TESTING ¼ Wave Antenna footnote

in this appendix).

The basic parts of the system are:

1) PC running a terminal program and a serial cable from PC COM port to

base RF401/RF411

2) Base RF401/RF411

3) Remote RF401/RF411 with RS-232 port jumper wire between TX (pin 2)

and RX (pin 3) for data loop-back.

Build the RF401/RF411 test system in the order shown:

1) TESTING SC12 CABLE and PC COM PORT

2) TESTING RF401/RF411s

3) TESTING ANTENNAS

Label components of the system “known-good” as they pass the test.

TESTING SC12 CABLE and PC COM PORT

(1) Run a terminal program such as HyperTerminal

or Procomm

(a) Baud rate: 9600

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