Com Port; Rs232 Serial Port; Usb Client Port; Audio Headset Connection - Honeywell MX8 User Manual

Backup Battery
An internal 160mAh Nickel Metal Hydride (Ni-MH) battery. The backup battery is recharged directly by the MX8 main
battery pack. Recharging maintains the backup battery near full charge at all times. When the backup battery is fully
drained, it may take up to 5 hours to recharge. The capability to discharge the backup battery is provided to allow the user
to condition the battery in order to recover full battery capacity. The backup battery must be replaced by qualified service
personnel. The battery has a minimum 2 year service life.
Note: An uninterrupted external power source (wall AC adapters) transfers power to the MX8's internal charging circuitry
which, in turn, recharges the main battery and backup battery. Frequent connection to an external power source, if
feasible, is recommended to maintain backup battery charge status as the backup battery cannot be recharged by a
dead or missing main battery.

COM Port

The MX8 has one 20-pin multifunction I/O port that can be configured by the user.
Note: The MX8 AC Power Adapters (MX8301PWRSPLY and MX8302PWRSPLY) are only intended for use with the MX8
multi-purpose cables and the MX8 Desktop Cradle.

input, stereo or mono output. The MX8 with a Summit Client supports mono only. A 3-wire connector with (at a minimum)
connections for ground, microphone, and 1 speaker. Connecting the headset to the MX8 COM port turns off audio output to
