Connecting to a PC
The procedure in this section describes how to connect the ISDN TA reference
design to a PC using either a USB or serial port. Follow the steps below to connect
the ISDN TA reference design board to your PC. For information on how to invoke
the software, see the Software Quick Start document included in your kit.
Installation Requirements
The items listed below are necessary to install and run the ISDN TA:
• PC with an available COM port
• Terminal emulation software (such as Microsoft

Windows

Terminal or
ProComm Plus) that supports ASCII file transfers, software flow control (Xon/
Xoff), and send break capability
• Dial-up networking configured as per your ISP’s recommendations
• Power source for universal power supply (47–63 Hz, 100–250 VAC)
Board Installation
CAUTION: As with all computer equipment, the ISDN TA may
be damaged by electrostatic discharge (ESD). Please take proper
ESD precautions when handling any board.
1. Remove the board from the shipping carton. Visually inspect the board to verify
that it was not damaged during shipment.
2. Connect the ISDN TA board’s DB-9 serial port to an available COM port. Use
the serial cable included in the ISDN TA kit and note that a DB-9 to DB-25
serial connector adapter is provided if your host system requires it. If using
your own cable, use a straight through cable, not a null modem cable.
DANGER: Make sure the power supply is
not plugged into
an electrical outlet before connecting it to the ISDN TA.
