Ethernet 10/100 Interface Connector 4.1.3
The RJ45 connector for the Ethernet 10/100 Mbps link is mounted directly on the
BLA Control Board.
Table 4.3. RJ45 Pin Assignment
IN1, IN2, IN3 RF inputs of the embedded router, SMA type connector (female).
Default entry is IN1 and allows to the BLAH1000 E to deliver full power at
nominal +4dBm drive.
MAIN OUT
1000W/100W
RF output of 1000W if MAIN OUT LED is on, N type connector (female).
This is based on the SEL H1000/H100 selection.
AUX OUT
1000W/100W
RF output of 100W if MAIN OUT LED is off, N type connector (female).
This is based on the SEL H1000/H100 selection.
BLNK Blanking input, BNC type connector (female).
TTL logic, 5V = blanking ON, 0V = blanking OFF.
When BLANKING signal is at TTL level high (+5V), no gating is applied to the
amplifier stages, and no RF Power is possible.
When BLANKING signal is at TTL level low (0V), the amplifier stages are gated
and RF Power is possible.
SEL H1000/H100 Select input, BNC type connector (female).
When the SEL H1000/H100 signal is at TTL level low (0V), the 1000W channel
for Solid application is selected.
When the SEL H1000/H100 signal is at TTL level high (+5V), the 100W
channel for High Resolution application is selected.
