Page 13: Edl Ii Setup
After installing the software, connect the EDL II to your computer and click the desktop icon called Environmental Data Link. You will be able to view the EDL II configuration, as well as change its settings. See the online Help for a description of the various settings. - Page 14 Mount The EDL II is designed to mount in the same location as the antenna. Pole mounting is accomplished by fastening the EDL II onto the mounting hardware (PCC PN A01766 for horizontal surfaces, PCC PN A01765 for vertical surfaces).

EDL II User’s Guide Being Part of the RF Community Operation of a licensed radio product makes you a member of the RF community. Be aware that virtually all licensed frequencies are provided on a shared basis with other users. -
Page 21: Carrier Sense Multiple Access (Csma)
FCC call sign to enable this capability. Carrier Sense Multiple Access (CSMA) CSMA is a technology implemented in the EDL II to meet FCC transmitter requirements. CSMA holds off the radio transmission if the frequency is currently being used by a co-channel user. On occasion, you may note that the radio broadcasts stop for short periods of time. - Page 22 This page intentionally left blank.
