Communicating with the Dolphin Terminal

To initiate communications between the Dolphin terminal and peripheral, complete these steps:


Insert the Dolphin terminal into the terminal well of the base.

• The DOCK LED illuminates green. If the DOCK LED does not illuminate, make sure that the terminal is

properly seated. You may need to remove and re-insert the terminal.

• The Dolphin terminal activates; if the power is off, the terminal automatically powers on. If the terminal does

not power on, verify that the Honeywell power supply is properly connected to the cradle and plugged into a
functioning outlet.

• If the base is connected to the workstation, the Dolphin terminal automatically opens ActiveSync to establish

a connection.


The base can now transfer data between the terminal and the host device. If communication does
not occur, check the port connections to ensure that the cradle is correctly configured.

Verifying Communication

You can verify that the USB driver is functioning by watching the COMM LED on the USB base. When
the COMM LED illuminates solid green, the base is communicating with the host device.

Verifying Data Transfer

The COMM LED flashes when data is being transferred via the base. For an RS-232 connection, the
COMM LED flashes red and green. For a USB connection, the COMM LED flashes green.

RS-232 Communications Cables

Connect the base to the host workstation or other device by plugging an RS-232 serial cable into the RS-
232 Communications Port on the rear of the base. 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 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 workstation, 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
