Page 5: Sco-1421 Intelligent Asi Change-Over With Probing
GUIDE TO INSTALLATION AND OPERATION 1 SCO-1421 Intelligent ASI Change-Over with Probing 1.1 Introduction The SCO-1421 is a 2x1 intelligent ASI change-over with built-in MPEG-TS probing. Changeovers are performed electronically by the SCO-1421’s internal router. In the event of a power failure, the signal is protected by relays fitted on the rear module, maintaining the integrity of the selected signal at the output. -

If any of the following items are missing, contact your distributor or Miranda Technologies Inc. • SCO-1421 Intelligent ASI Change Over with Probing •... - Page 8 GUIDE TO INSTALLATION AND OPERATION When constructing and using an external GPI box, be aware of the following: The SCO-1421 card monitors the external power supply voltage on the GPI input. If the voltage is less than 4V (per relay datasheet), an alarm will be raised. When a GPI INPUT is triggered while the card is operating in auto mode, the card changes to manual mode and switches to the input selected by the GPI.

Page 9: Operation
GUIDE TO INSTALLATION AND OPERATION 3 Operation 3.1 Getting Started The switch mode is set to AUTO by default which means the card will automatically switch to the input with the less errors based on the error configuration that has to be done in the ALARM tab. Don’t forget to change this setting if you don’t want the card to switch by itself. -

Page 16: The Alarms Panel
GUIDE TO INSTALLATION AND OPERATION e Alarms 3.5.4 panel The SCO-1401 continuously monitors the condition and status of the input signals it is processing. The information is used to decide whether the input must be switched in Auto mode. It is also used to flag the status of the card in the iControl system. - Page 17 GUIDE TO INSTALLATION AND OPERATION TS – TS signal presence This error is always ENABLED and the level set to 1, 2 or OFF. The factory default value is level 1. Use the slider to set the duration for which the error must continuously exist before the alarm is flagged.
- Page 18 GUIDE TO INSTALLATION AND OPERATION TS – PAT Presence This error is generated if the PAT (Program Association Table) of the input transport stream is continuously absent for a period greater than the time set in the Duration data box. •...
- Page 19 GUIDE TO INSTALLATION AND OPERATION TS – SI Tables Presence (Only available when the Advanced Probing option is enabled) This error is generated if the Service Information tables in the input transport stream service that has been selected for probing are continuously absent for a period greater than the time set in the Duration data box.
- Page 20 GUIDE TO INSTALLATION AND OPERATION Bit Rate – PID n Bit Rate (Only available when the Advanced Probing option is enabled) This error is generated if the bit rate for a specific PID in the input transport stream is continuously outside a specified range of values for a period greater than the duration set in the data box.
- Page 21 GUIDE TO INSTALLATION AND OPERATION TR 101 290 – 1.1 TS_sync_loss This alarm is set if the transport stream synchronization is lost. This is the same as the Transport Stream Presence error in the TS tab, and the Level is fixed to the value set there. It is shown here because it is included in the TR 101 290 set.
- Page 22 GUIDE TO INSTALLATION AND OPERATION TR 101 290 – 1.3c PAT_scrambling_error (Only available when the Advanced Probing option is enabled) An error occurs if the s crambling_control_field is not 00 for the PAT PID ( 0x0000). An error is reported at the first scrambling error and the error will remain for few seconds…...
- Page 23 GUIDE TO INSTALLATION AND OPERATION TR 101 290 – 1.3a PAT_error_2 (Only available when the Advanced Probing option is enabled) An error occurs if the PAT PID (0x0000) does not occur for at least the time specified by Repetition Rate slider. The error will remain for few seconds after the PAT returns.
- Page 24 GUIDE TO INSTALLATION AND OPERATION TR 101 290 – 1.5a PMT_error_2 (Only available when the Advanced Probing option is enabled) This error occurs if a PMT that is part of a service selected for probing (see TS tab…) is not present for the time specified by the Repetition Rate slider.
- Page 25 GUIDE TO INSTALLATION AND OPERATION TR 101 290 – 1.6 PID_error (Only available when the Advanced Probing option is enabled) This error occurs when there are PIDs with no associated datastream This is the same as the Service Presence error in the TS tab, and the Level is fixed to the value set there.
- Page 26 GUIDE TO INSTALLATION AND OPERATION TR 101 290 – 2.2 CRC_error (Only available when the Advanced Probing option is enabled) The CRC check for the CAT, PAT, PMT, NIT, EIT, SDT and TOT indicates whether the content of the corresponding table is corrupted.
- Page 27 GUIDE TO INSTALLATION AND OPERATION TR 101 290 – 2.3b PCR_discontinuity_indicator (Only available when the Advanced Probing option is enabled) The PCR_discontinuity_indicator_error is set in the case that a discontinuity of the PCR values occurs that has not been signaled appropriately by the discontinuity indicator. An error will only be flagged if the error rate exceeds the tolerance set using the slider, over the range 0 to 10 errors/sec.
- Page 28 GUIDE TO INSTALLATION AND OPERATION TR 101 290 – 2.5 PTS_Error (Only available when the Advanced Probing option is enabled) The Presentation Time Stamps (PTS) should occur at least every 700 ms. They are only accessible if the TS is not scrambled. An error will only be flagged if the timeout period of the PTS exceeds the tolerance set using the slider, over the range 20 to 5000 msec.
- Page 29 GUIDE TO INSTALLATION AND OPERATION TR 101 290 – 2.6b CAT_error (Only available when the Advanced Probing option is enabled) This alarm is triggered when a section with table_id other than 0x01 (i.e. not a CAT) is found on PID 0x0001, which is reserved for CAT tables.
