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 RS232 and USB communication. For RS232, the maximum communication
speed is 115.2 Kbps with seven baud rate settings. For USB, the communication speed is up to 12 Mbps.
I/O Power 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, but the
5V output may be turned on programmatically.
