I/O Connector
Note: Signals referenced are for a DTE device.
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 or USB. 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 mechanical connector also provides power out (to peripheral devices) 5V at 500mA. This means that,
with the proper Honeywell 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
