ATSC SMPTE 310

signal status Off SMPTE 310 19.39 Mb/s ATSC
signal is not detected. None None.
Green SMPTE 310 19.39 Mb/s ATSC
signal is received or transmitted. None None.
Yellow SMPTE 310 19.39 Mb/s ATSC
signal is detected and is being
converted to ASI. None None.
Red SMPTE 310 19.39 Mb/s ATSC
signal is detected and blocked.
1. A video rate unlocked condition usually indicates that the input signal rate is outside the standard rate requirements.
ASI is the signal type most often found to not meet the rate requirements.
The input signal rate requirements are as follows:
- SDI/ASI rates must be 270 Mb/s ± 100ppm
- HD SDI rate must be 1.485 Mb/s or 1.485/1.001 Mb/s ± 50ppm
- 3G SDI rate must be 2.97 Gb/s or 2.97/1.001 Gb/s ± 50ppm
If the signal cannot be held within these requirements, try setting the DLC300 to bypass mode (see the
Note
associated
with
Table 3
).
2. When the DLC300 is in repeater mode, the TX and RX status LEDs are active to represent the simultaneous receive and
transmit operations occurring.
Using the Monitor Jack
To monitor the DLC300 transmit and receive signals, connect the monitor cable to the mini 75 Ohm SMB
monitor jack (MON) located on the DLC300 front panel (see Figure 7) .
The monitor output in transmitter mode is always the same signal as the optical output except that it is not
dithered.
Note: When the DLC300 is operating in transmitter mode and is configured to convert ATSC
(SMPTE 310M) to ASI, the monitor output is the ASI signal that was converted from ATSC. The
unconverted ATSC signal is available at the BNC OUT connection on the rear panel.
