Demo Board Basic Connections
- Use the supplied motherboard and 5 V power supply.
- The motherboard includes a 3.3 V regulator to power the 73M2901CE Demo Board.
- The motherboard also includes RS-232 level shifters and DCE connector to connect the demo board to a PC or other terminal device.
- Use a standard PC terminal emulation program to communicate with the 73M2901CE Demo Board. See the 73M2901CE AT Command User Guide for a complete list of commands.
- Type "AT" on the terminal at any speed from 1200bps to 9.6Kbps to verify communications with the modem are working correctly. The 73M2901CE modem will return "OK" if communication is properly established.
- Connect the RJ-11 connector to a telephone network emulator or private branch exchange (BPX). The demo board, although meeting all the required telecom standards, is not a certified device. Therefore the 73M2901CE Demo Board should not be connected to the outside telephone network.
