Hand Held Products 7400, 7450 Installing The Charging/Communication Cradle, Connecting the Cables

The IrDA 1.0 software stack is integrated into the IntelliBase and IntelliBase+ cradles to allow communication between the cradle and devices such as modems or printers that are not IrDA ready or do not communicate with a half duplex serial protocol. This allows any full or half duplex RS-232 device to communicate through the IntelliBase/IntelliBase+ with no IrDA protocol software. See Table 2 for the baud rate switch settings.

Installing The Charging/Communication Cradle

To install and use the IntelliBase or IntelliBase+, you need the following equipment:

•IntelliBase/IntelliBase+ with power supply

•Serial cable

Set the Dolphin IntelliBase/IntelliBase+ on a dry, stable surface, such as a desktop near an electrical outlet. Be sure to provide enough workspace with good lighting for the user to view and operate the Dolphin terminal while it is in the IntelliBase.

Connecting the Cables

Connect the IntelliBase/IntelliBase+ 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 IntelliBase. The wiring of your cable depends on whether the other device is set up as a DCE (Data Communications Equipment) or DTE (Data Terminal Equipment) device.

The IntelliBase Communication Port is configured as a DCE device. To communicate with a DTE device such as a computer, use a standard (or straight-through) RS-232 cable. 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.

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.

IntelliBase /Host		IBM AT DB9	IBM XT	Modem DB25
Port (DCE)		(DTE)	DB25 (DTE)	(DCE)
Pin / Input Signal
2	/ (RD)	2	3	2
3	/ (TD)	3	2	3
5	/ (SG)	5	7	7
4	/ (DTR)	4	20	6
6	/ (DSR)	6	6	20
7	/ (RTS)	7	4	5
8	/ (CTS)	8	5	4

The IntelliBase/IntelliBase+ cannot be daisy-chained.

Connect the power supply to the charging/communication cradle. Plug the AC transformer into the Dolphin IntelliBase/ IntelliBase+ 5 Volt DC power supply connector. The AC wall transformer provided can power only one IntelliBase/IntelliBase+. HHP recommends that you leave the Dolphin IntelliBase/IntelliBase+ connected to its power source at all times, so that it is always ready to use.

Set the baud rate switch to the communication mode you are going to use. Refer toTable 3 for IntelliBase/IntelliBase+ switch settings.
