    Figure 2.3.5 shows a conceptual signal flow diagram of the re-transmission. The use of MAC-level re-transmission protocol, recommended by 802.11 draft standard, is important for high throughput. Re-transmission via the level-four transport protocol must be avoided because of the long time-out typically employed. M10 SERIES USER’S MANUAL PAGE 9...

    2.3.8 ANTENNA RECOGNITION (ANTENNA SENSE CIRCUIT) M10 uses a standard SMA connector for the attachment of external only antennas. Although there is a standard SMA connector Clarion approved antennas will work due to the Antenna Sense Circuit. Antenna Sense Circuit is an electrical verification that the attached antenna is FCC approved for use with the M10.
