USER'S MANUAL. MO-16X
4.15.1 Types of errors
The control program of the MO-16X can detect and show up to 4 types of errors.
Some of them correspond to instrument malfunction and must be directly reported to a
PROMAX's Customers Service Centre (CSC). Others state incorrect options about
modulator input signals.
1.
NAK: An internal device connected to control I
messages from the microcontroller. It requires service of CSC.
2.
UNKN: Unknown error. Due to a problem different to the one previously
described, the I
CSC.
3.
BUSY: The I
operation. It requires service of CSC.
4.
MOD FAIL: It covers all errors corresponding to the MPEG-2 transport stream
inputs not being correctly synchronized and/or not having the right bit rate.
4.15.2 Error Coding
NAK, BUSY and UNKN are for internal use of PROMAX. If any of these errors
occurs repeatedly, the equipment ought to be taken to a PROMAX's customer service
centre for repair.
UNLOCKED STATUS
The display format for this type of error is as follows:
ERRnn UNLOCKED STATUS: XXYY (CC...CC)
When this type of errors occur, the MO-16X presents an error message on the
LCD display starting with the word STATUS and followed by an explanation of the type
of error. Under these circumstances, the ERROR LED flashes red for 5 seconds, and
then stays lit until Clear Errors under the STATUS menu is set to YES.
This type of error either indicates problems with some of the circuitry
implementing the modulation process or synchronisation errors with the different input
signals.
