Upgrading the Modem Firmware
Your Premier 56 modem can have its firmware upgraded in the field, without having to return the
modem to Telenetics. To upgrade the firmware, you need:
™ A personal computer running HyperTerminal.
™ An straight-through RS-232 cable (at least 8 pins) that supports all control signals.
™ The loader and data files from Telenetics.
To upgrade the modem firmware:
1.
Make a directory on your computer’s hard drive. In that directory, place the loader and data files
supplied by Telenetics. The loader file has the word load in its name (for example,
F44Aload.S37), while the data file has the prefix rc (for example, rc_111003.S37).
2.
Connect one end of the RS-232 cable to your computer’s serial port. Connect the other end of the
cable to your Premier 56 modem.
3.
Turn on the modem, then reboot your computer. After your computer reboots, close all other
applications that may have opened automatically.
4.
Start HyperTerminal and configure your session to use the following parameters:
™ Baud rate: 115,200 bps
™ Data bits: 8
™ Parity: None
™ Stop bits: 1
™ Flow control: Hardware
5.
Verify that the PWR, DIR, RTS, and CTS LEDs on the Premier 56 modem are ON.
