I/O Connector
Note: Signals referenced are for a DTE device.
I/O Connector
The bottom panel features a custom, industrial-grade mechanical connector with 17 pins. When seated in a Dolphin 7900 Series
peripheral, the terminal is powered, the main battery charged, and communication occurs via this connector. All Dolphin 7900
Series peripherals are designed to work exclusively with this connector.
The 17-pin connector communicates with Dolphin peripherals via 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. If the peripheral unit is
connected to a PC, this connector also transmits data.
Powering Out
The I/O connector also provides power out 5V at 500mA. This means that, with the proper Hand Held Products 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
