Modulator Settings for A &B channel where appropriate
Note:
RF output bandwidth separation not less than set bandwidth or more than 32MHz.
E.g. Channel A: 599.500 & Channel B: 606.500 MHz
Set the output frequency (centre digital frequency, not analogue carrier).
Set the RF output frequency (MHz) to designed digital channel
Set the Bandwidth to
7MHz
.
Set the Guard Interval to
1/16
Set the Constellation to
64QAM
Hierarchy information to
Not Hierarchy
Set the Code Rate to
3/4
.
Transmission Mode to
8K
Edit NIT table Settings
Visible box should be ticked for all Service ID and LCN settings
Service ID 0x111 LCN e.g. 501 (Set the LCN (Logical Channel Number) for inputs 1 to 4,
to avoid conflict
with Free-To-Air channels, start the LCN numbers at 500 (unallocated numbers) and do not go any
higher than 549
.)
Service ID 0x112 LCN e.g. 502 (Set the LCN (Logical Channel Number) for inputs 1 to 4 t
o avoid conflict
with Free-To-Air channels, start the LCN numbers at 500 (unallocated numbers) and do not go any
higher than 549
.)
Service ID 0x121 LCN e.g. 503 (Set the LCN (Logical Channel Number) for inputs 1 to 4,
to avoid conflict
with Free-To-Air channels, start the LCN numbers at 500 (unallocated numbers) and do not go any
higher than 549
.)
Service ID 0x122 LCN e.g. 504 (Set the LCN (Logical Channel Number) for inputs 1 to 4,
to avoid conflict
with Free-To-Air channels, start the LCN numbers at 500 (unallocated numbers) and do not go any
higher than 549
.)
The service ID (SID) and LCN must be changed if combining or cascading HMT products
For second unit SID and LCN would be
0x211 LCN 505 0x212 LCN 506, 0x221 LCN 507, 0x222 LCN 508
Ikusi has picked these SID to make it easer to recognised which unit is which 0x 111 first character
represents HMT unit 1 second character the input module in unit, 3
rd
character represents the HDMI
stream
SID needs to be changed in the Input1 & Input 2 screens.
SID and LCN also need to be changed in NIT (A & B) table by selecting detail and editing and saving
changes
Firmware updates
When updating firmware do not try to restore configuration from a previous firmware version as this may
corrupt settings.
After upgrading firmware you will need to reboot HMT via the browser, do not switch on and off.
Save configuration via the browser.
In restore / save menu load factory reset via browser.
After steps above manually adjust input setting modulation setting and NIT table setting.
Save configuration check unit operates OK, and then power cycle unit (not reboot) and check again if OK
make backup configuration file if required
Final points
Check welcome page Status/Alarm are OK
TS overflow should be green for both A & B as appropriate to model being used
