Appendix K. RF400/RF410 Pass/Fail Tests

(9)Make sure that no antennas are attached to the RF400/RF410s

(10)Label the other RF400/RF410, “Remote”

(11)Insert jumper into the Remote RF400/RF410’s RS-232 connector pins 2 and 3 (using a U-shaped portion of a paper clip) allowing data received from base RF400/RF410 to be transmitted back to terminal screen by remote RF400/RF410.

RF400/RF410’s RS-232 Connector (female)

NOTE

CAUTION

(12)Connect 12V power to Remote RF400/RF410. This can be supplied by an AC adapter (Item # 14220) or Field Power Cable (Item # 14291) connected to a 12V battery (battery can be an 8 cell pack of alkaline A, C, or D cells, or a lead-acid battery).

If your 12V power supply is a battery pack or rechargeable battery, make sure that the batteries are fresh or well-charged so they can supply the 75 mA peak current needed when the RF400/RF410 is transmitting in order to obtain valid test results.

For safety, people should maintain 20 cm (8 inches) distance from antenna while RF400/RF410 is transmitting.

(13)Type 8 groups of 5 characters on the terminal (aaaaabbbbbccccc etc.)

(14)You should see 100% of the characters typed echo back to the screen

TESTING ANTENNAS

After setting up the terminal program and verifying the integrity of the COM port, serial cable, and RF400/RF410s, you are ready to test an RF400/RF410 antenna. Prepare to test an antenna by:

•Orienting RF400/RF410s so that the antenna connectors are on top

•Fastening RF400/RF410s to cardboard boxes or other non-metallic structures maintaining antenna connectors 20 inches above the floor.

(1)TESTING ¼ Wave Antenna

(a)Connect 12V power to base RF400/RF410 and remote RF400/RF410.

We recommend AC adapter Item # 15966 or a Field Power Cable Item # 14291 connected to a 12V battery pack or 12V power supply.1
