7.0 Troubleshooting
All OUTPUT channel LEDs are off.
Check to see if there is at least one RF input to the instrument with a level greater than +7
dBm. Check that the active channel is set to the input that has the proper signal level.
If the OUTPUT signal status LEDs remain off the instrument will have to be returned for
repair.
One OUTPUT channel LED is OFF the rest are ON.
If the instrument has at least one input signal and the active channel is set to that input, all
the output signal status LEDs should be illuminated. If one of the OUTPUT signal status
LEDs is off, disconnect the output cable from that output channel. If upon disconnecting
the cable from the instrument the status LED is illuminated then there may be a short in
the cable or the load. Check the cable and load for a signal fault. Contact SDI technical
support if the condition persists.
Cannot connect to the instrument through the Ethernet port.
Check the network cable and run the Digi Device Discovery Tool software on a computer
that is attached to the same network as the HPDA-15RMi-S. The software should be able
to locate the HPDA-15RMi-S and display the network setting of the instrument. If the
instrument does not appear in the list of devices on the main screen click the refresh
button. If the error persists try resetting the power on the HPDA-15RMi-S. Check with your
network administrator and make sure that the HPDA-15RMi-S is not blocked by a firewall.
For further assistance contact SDI technical support.
If the instrument is found by the software tool, try opening a telnet session with the
instrument using the displayed network settings on port 23. Type *ID<cr>, the instrument
should respond with its model and serial number.
Unreachable IP address was programmed and cannot connect with the HPDA-
15RMi-S.
