Table 1. Status LED Descriptions
LED Color Display and Description
INPUT OK Green
When lit, this LED indicates presence of a valid SDI input signal.
AES 1 Green
When lit, this LED:
•
Indicates presence of a valid AES input signal
•
Shows that the incoming signal is sampled at 48kHz
When flashing, and the ERROR LED is also flashing, this LED indicates there
is a problem with the AES 1 input signal. The AES input stream will continue
to be embedded. However, one of the following problems has been
encountered:
a. CRC Error – There is an error in the CRC calculation
b. Validity – The integrity of the AES input signal is in question
c. Sample Slip – The AES sample is repeated/dropped due to improper
timing
d. Coding – Bi-phase coding violation
e. Parity Error – There was a parity error
f. No Valid AES Input
g. Rate Error – The Sample Rate does not equal 48kHz
When not lit, this LED indicates that there is no AES signal present.
AES 2 Green
When lit, this LED:
•
Indicates presence of a valid AES input signal
•
Shows that the incoming signal is sampled at 48kHz
When flashing, and the ERROR LED is also flashing, this LED indicates there
is a problem with the AES 2 input signal. The AES input stream will continue
to be embedded. However, one of the following problems has been
encountered:
a. CRC Error – There is an error in the CRC calculation
b. Validity – The integrity of the AES input signal is in question
c. Sample Slip – The AES sample is repeated/dropped due to improper
timing
d. Coding – Bi-phase coding violation
e. Parity Error – There was a parity error
f. No Valid AES Input
g. Rate Error – The Sample Rate does not equal 48kHz
When not lit, this LED indicates that there is no AES signal present.
Green
When lit green, this LED indicates there is a valid audio and vido input
signal(s) and the card is configured properly.
ERROR/OK
Red
When lit red, this LED indicates one or more of the following errors:
•
Indicates AES is selected on jumper JP10 , but neither AES input
signal is present or valid.
•
Indicates no valid SDI input, or card not locked to SDI input.
When flashing red, this LED indicates that group select jumper JP11 is set to
overwrite pre-existing audio on the selected AES group without jumper JP7
being set to overwrite.
