Honeywell International Inc. 950009 Manuale Utente

The HomeBase supports RS-232 communications via the RS-232 Communications Port located on the back of the device. Tis 
port enables the Dolphin terminal to communicate to a personal computer, modem, or any RS-232 device using a standard serial 
cable and communications software.

The HomeBase also supports USB communications via the USB port located on the back. The HomeBase acts as a USB device 
by interfacing the USB signals of the Dolphin 9500/9550 to the USB of the host computer. Using a standard USB cable, the 
HomeBase’s USB interface allows the Dolphin terminal to communicate with a personal computer or to be networked through a 
USB hub.

Note: The HomeBase should have only one type of interface cable connected at a time, either USB or RS-232. You must be 

using ActiveSync, version 3.7 or higher.

To install and use the HomeBase, you need the following equipment:

•

HomeBase connected to the appropriate power supply

•

For RS-232 communications, a Serial cable 

•

For USB communications, a USB cable 

Use only the power and communication cable from HHP. 

Connect the HomeBase to the host computer or other device by plugging an RS-232 serial cable into the RS-232 
Communications Port on the rear of the HomeBase. The wiring of your cable depends on whether the other device is set up as 
a Data Communications Equipment (DCE) or Data Terminal Equipment (DTE) device. 

The HomeBase Communication Port is configured as a DCE device. To communicate with a DCE device, use either a null 
modem adapter in line with a standard RS-232 cable, or a null-modem serial cable. To communicate with a DTE device such as 
a computer, use a standard (or straight-through) RS-232 cable.  

You can make your own cables by following the pin configuration in the chart below. To do so, you must determine if your host 
RS-232 device is 9-pin or 25-pin, and whether it is configured as a DCE or DTE device.

Note: The HomeBase cannot be daisy-chained.
