Bottom Panel Features
This following graphics describe the bottom panel of the Dolphin 9500/9550.
Mechanical Connector
The bottom panel of the Dolphin 9500/9550 features a custom, industrial-grade connector with 17 pins. When seated in a Dolphin
9500 series peripheral, the terminal is powered, the main battery charged, and communication occurs via this connector. All
Dolphin 9500 series peripherals are designed to work exclusively with this connector.
The 17-pin connector can communicate with Dolphin 9500 series peripherals via RS-232 or USB. For RS-232, the maximum
communication speed is 115 Kbps with a seven baud rate setting. For USB, the communication speed is 12 Mbps. If the
peripheral unit is connected to a PC, this connector also transmits data. This serial port is designated as COM port 1 on the PC.
The mechanical connector also provides power out (to peripheral devices) 5V at 500mA. This means that, with the proper HHP
cable, the terminal can power another device.
