I/O Connector
The I/O connector powers the terminal, charges the main battery, and facilitates communication. All
Dolphin peripherals are designed to work exclusively with this connector.
The I/O connector supports RS-232 and USB communication. For RS-232, the maximum communication
speed is 115 Kbps with seven baud rate settings. For USB, the communication speed is up to 12 Mbps.
Powering Out
The I/O connector also provides power out (to peripheral devices) 5V at 500mA. This means that, with
the proper cable, the terminal can power another device. By default, power out is disabled. To enable
power out, alter the registry as follows:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Serial4]
Conn5Venable=1
