The status bar will indicate:

0 (R

ED

): if the video encoder is not responding

1 (G

REEN

): if the video encoder is actively responding to control com-

mands

1.

If the indicator remains R

ED

, shut down the baseband unit and remove all

power sources for at least 30 seconds.

2.

If the problem persists, contact Norsat Customer Support.

The transmitter, located at the base of the antenna, converts the L-band sig-
nal to a Ku-band signal. 

Operating Range: 

800 - 1200 mA

Note that when the transmitter is OFF, this indicator bar is always G

REEN

regardless of how much current is being consumed.  

1.

Ensure that the transmitter is turned ON; refer to the 

T

RANSMITTER

 C

ONTROL

screen.

2.

If the current is too low, i.e. equal to zero, ensure that one end of the R

ED

cable is plugged into the N jack marked R

ED

, labeled T

X

, on the baseband

unit, and the other end of the R

ED

 cable is plugged into the N jack marked

R

ED

, labeled T

X

, on the dish elevation support panel.

3.

If the current is still too low, too high or if it keeps fluctuating between nor-
mal and alarm, turn the transmitter OFF, power down the system, and
inspect the connectors on both sides of the R

ED

 marked; replace if neces-

sary. If no replacement is available, the R

ED

 marked cable may be substi-

tuted with the B

LUE

 marked cable by following the instructions in the

Troubleshooting chapter.

4.

Inspect the short jumper cable connected between the transmitter and the
dish elevation support panel. 

5.

IF the current is between 100 and 200 mA, ensure that ambient tempera-
ture around transmitter is lower than 50 degrees C, or higher than -30
degrees C.

6.

If the problem persists, contact Norsat Customer Support.

If this value exceeds the maximum allowable range, the transmitter will auto-
matically shut down.

The SSPA, i.e. power amplifier, located at the base of the antenna, amplifies
the transmitted Ku-band signal. Note that when the transmitter is OFF, this
value is always G

REEN

 regardless of how much current is being consumed.

Operating Range: 

15W SSPA: 5000 - 8000 mA.
