Signaling Encoder and Decoder - Screens and Control Fields

Control Fields for the Signaling Encoder and Decoder

Data Level

This setting determines the signal level change that occurs when a logical high (1) or low (0) is output. The unit-of-measure used depends on the AFGen2 To setting. The direction of the output level change depends on the Polarity setting.

Screens Where Field is Present

SIGNALING ENCODER (Modes: AMPS-TACS, NAMP-NTAC)

Data Rate (analog)

Signaling Decoder

This measurement field displays the data rate in bits-per-second for the data stream being received.

The encoder screen’s Data Rate field tells the decoder how fast the incoming message is being sent. Set the Data Rate field’s value before using the AMPS-TACS or NAMPS-NTACS decoder.

Signaling Encoder

This field specifies how fast the data stream is output in bits-per-second.

This setting is also used to determine the turn off code frequency (TOC frequency Hz = Data Rate in bps). Example: 1000 bps = 1 kHz

This field specifies the data rate for the signal being decoded, and must be set before using the AMPS-TACS/NAMPS-NTACS decoder.
