Modem Power Up
The modem has a dip switch that will override certain NVRAM settings during a power up. For
consistent operation throughout the power cycles, you must set the dip switches as follows.
Configuration Settings
After configuring the dip switch settings, you must set up each modem configuration using a terminal
program such as Microsoft Windows HyperTerminal.
Using the manufacturer’s recommendations, connect the modem to the serial port on your PC using a
DB9-25 modem cable.
Set the terminal communication parameters as follows:
• 9600 baud
• No parity
• 8 bits per character
• 1 stop bit, and no flow control
Table 4-5 gives a brief description of the modem settings that can be stored in NVRAM. These settings
will survive power supply interruptions. Use these settings to configure each modem.
