I/O Connector
The I/O connector powers the terminal, charges the main battery, and facilitates communication. All Dol-
phin peripherals are designed to work exclusively with this connector.
The I/O connector supports RS232 and high speed USB v2.0 communication. For RS232, the maxi-
mum communication speed is 115.2 Kbps with seven baud rate settings. For USB, the communication
speed is up to 480 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 enabled, see
Five Volt Control on page 7-12.
