Demodulator Checkout
The following descriptions assume that the MD2401 is installed in a suitable location with prime
AC power and supporting equipment available.
2.4.1 Initial Power-Up
The MD2401 is shipped from the factory with preset factory defaults. Upon initial power-up, a
user check should be performed to verify the shipped demodulator configuration.
The following are standard MD2401 Factory Configuration Settings:
Data Rate:
2,048 Kbps
Forward Error
Correction (FEC):
1/2 Rate Viterbi
Frequency:
950 MHz (L-Band)
Interface:
RS422
Turn on the unit by placing the Rear Panel Switch (located above the power entry connector) to
the On position. Upon initial and subsequent power-ups, the MD2401 Microprocessor will test
itself and several of its components before beginning its Main Monitor/Control Program. These
power-up diagnostics show no results if successful. If a failure is detected, the Fault LED will
illuminate.
The initial field checkout of the modem can be accomplished in Terminal Mode. The Terminal
Mode has the advantage of providing full screen access to all of the modem’s parameters, but
requires a separate terminal or computer running a terminal program.

The factory terminal setup is as follows:
Emulation Type:
VT-100 (can be changed)
Baud Rate:
