o Button: a short press on B3 will disable TPC and set fixed output power setting.
additional press will increment the power according to the following power Steps:
11, 14, 17, 20 & 8 dBm
o LEDs: LEDs L6, L5 & L3 indicate the power level of the Tx in binary mode. L6
marks LSB and L3 marks MSB. Upon power change the relevant LEDs will blink
for a few seconds
5.7 Manual frequency selection
By default, the transmission RF frequency is decided automatically by the system’s
Automatic Frequency Selection (AFS) mechanism, out of the pre-defined frequency
table. It is possible to disable AFS and select the frequency manually.
o Button: a short press on B2 will disable AFS and set fixed transmission
frequency. Each press will switch to the next frequency in the pre-defined
frequency table.
o
LEDs: LEDs L6, L5 & L3 indicate the selected frequency in binary mode. L6
marks LSB and L3 marks MSB. Upon frequency change the relevant LEDs will
blink for a few seconds
5.8 Broadcast mode (both Tx and Rx)
This mode is used to set the system to broadcast mode. In this mode the Tx sends
the video unencrypted so any Rx that is set to broadcast mode can receive the video
without going through registration. Please note that even if HDCP is enabled in the
system – it will not work in broadcast mode. Setting broadcast mode is registered in
an EEPROM in the system and will remain even if powered down. In order to return
to unicast mode, repeat the process.
o Button: Upon power up
keep pressing all 3 buttons until L2 is blinking in red (do
it both for Tx and Rx). Repeat (upon power-up) to return to unicast.
o LEDs: L1 will blink slowly when in broadcast mode.
5.9 Link exists (both Tx and Rx)
After Link setup the Tx should transmits video frames and the Rx should receives
them. The following is the link indications:
o MAC does not response – L1 blink fast.
o MAC response but no LINK – L1 off.
o Link is active unicast – L1 solid.
o Link is active broadcast – L1 blink slowly.
5.10 Communication error (both Tx and Rx)
If there is a system error (such as bad I
2
C/SPI communication between the MAC and
the application), there will be a system error indication.
o LEDs: L1 fast-blinking yellow
