rev E Trango Systems, Inc. 1514 PTZ-900 Installation and Operating Instructions
Data not received.
9 Verify that a clear line of sight exists between the transmitter and
receiver antennas for distances greater than five hundred feet.
9 Check that the transmit and receive PN sequences, data rate, mode,
and address are set the same.
9 Verify that all connectors are tight.
9 Cycle the power.
9 Verify that transmitter and receiver antennas are aligned properly,
as discussed above.
Can’t communicate with
transmitter or receiver using TrangoLink.
Disconnect any peripherals connected to the terminal block. Plug the
supplied programming cable, CBLDAT-2, into the system’s DB9. Power
the computer on. Power the transmitter or receiver on, and within
twenty seconds run the TrangoLink program from Windows. The LED
will alternate between green and red to indicate that it is ready to talk
to the TrangoLink software. Important! Do not use any other cable for
this purpose.
