Hughes DW4020 manual Transmit status TxCode messages and corrective actions

If corrective measures do not solve a problem, contact technical support.

TxCode 8 means the transmit modem is working properly. It is the code you will see most of the time.

Note: Remember that IRU refers to the receive modem, and that

ITU refers to the transmit modem.

		• The 25-pin parallel cable is not properly connected to the Indoor Receive Unit
		or Indoor Transmit Unit: Check the cable and make sure the ends are securely
		fastened.
		• Indoor Transmit Unit failure. The Indoor Transmit Unit has failed and may need
		to be replaced.
1	The transmitter has been	This condition occurs when the transmitter is not enabled. A transmitter may be

		condition persists, it can only be corrected by requesting that the unit be
		enabled.
2	The transmitter has been	This status requires no user action and this test usually completes in 15 minutes

		mode, the unit is unable to transmit normal user data to the NOC.
3	The transmitter is locking to	This condition occurs during initial startup or when the receiver is locking to the

		persists for more than 10 seconds, try disconnecting and reconnecting the
		receiver coaxial cable and wait 10 seconds. If the situation still persists, then the
		Indoor Transmit Unit may need to be replaced.
4	The transmitter is not	This condition indicates that something is not operating properly in the

		• Verify that the Indoor Receive and Transmit Units are securely connected with
		a 25-pin parallel cable.
		• Reset the IRU by unplugging the IRU power cord from the wall socket and then
		plugging the power cord back into the wall socket. This will reset the Indoor
		Receive and Transmit Units.
		This condition could also be caused if the power supply is faulty. If this condition
		cannot be resolved by following the steps listed above, then you may need to
