OPERATION
3.1 SDM 309/M1200P Front Panel
3.1.1 General
The following is a Step by Step explanation and procedure for operating the SDM 309B
modem, hereafter referred to as the modem, with an internal IBS channel unit. The
complete front panel operation is described below.
The Modem front panel (Figure 3-1) provides the local user interface which is necessary
to configure and monitor status of the satellite modem. The front panel features a sixteen
character, two line LCD display and six key key-pad which provides for sophisticated
functions, yet is easy to use. Eight LED indicators are also present on the front panel to
provide overall status at a glance. All functions are accessible at the front panel by
entering one of five predefined ‘sELECT” categories or levels: Configuration
(CONFIG), Monitor, Faults, Stored Faults (StFaults), and Utility.
3.1.2 LED Indicators
General modem status and summary fault information is indicated by eight LED’s on the
front panel. The indicators are defined as follows:
Faults
Transmit (Red LED)
Indicates that a Modulator fault or a Transmit Interface
fault condition exists.
Receive (Red LED)
Indicates that a Demodulator/Decoder fault or a Receive
Interface fault condition exists.
Common (Red LED)
Indicates that a common equipment fault condition exists.
Stored (Red LED)
Indicates that a fault has been logged and stored. The
fault may or may not be active.
Status
Power On (Green LED)
Indicates power is applied to the modem.
Transmitter On (Green LED)
Indicates that the transmitter is currently on. This indicator
reflects the actual condition of the transmitter, as opposed
to the programmed condition.
Carrier Detect (Green LED)
Indicates that the decoder is locked.
