TN-052: HMT-402 & SERIES BASIC SETUP SHEET
Introduction
The HMT-402 is a stand-alone four HDMI inputs (HMT-201 & HMT-101 are dual and
single HDMI respectively) to DVB-T modulator. There are many settings in the DVB-T
modulators where conflicts can occur, so it is advisable to take some time to
familiarize yourself with the equipment, especially before attempting to install one.
Always refer to the operation manual where appropriate.
If you are using more than one HMT in a cable network, you will need to set
them up in a workshop beforehand, and make sure you have a laptop and LAN cable when installing.
This is a DIGITAL device. Firmware updates are available from link below, however if unsure please contact
Ikusi. https://sites.google.com/site/ikusitechnotes/
Overview
The HMT-4xx has a front-panel control and a web-based interface (NMS). For access to the full range of settings,
you will need to access the web interface of the HMT-4xx with Mozilla Firefox browser and a LAN cable for direct
connection. In this case, set a different IP address on each HMT, so you can access them easily.
Basic Setup
Where a setting is accessible only through the web interface, it will be denoted as (web). Otherwise, the setting is
able to be changed on the front panel, and will be denoted as (LCD). All settings on the front panel are able to be
configured through the web interface as well.
Remember, more than one HMT in a cable network requires access to the web interface.
System Settings (Web)
Set your computer or laptop LAN adaptor for 192.168.0.100
Set the subnet mask 255.255.255.0
If you are unsure how to do this, technote 42 can be used as a guide although it has been written for XP
computer and may be slightly different for windows 7 and upwards.
Use Mozilla or chrome browser and type in IP address 192.168.0.136
This will open a web interface with login admin password admin
Password can be changed, however you need to make sure you file information in a secure place
for future reference and access
Input 1 & Input 2 Stream/Services Settings
Setup input settings for HDMI inputs 1 to 4 selecting MPEG2 or H264 input dependant
Set video bit rate no higher than 10Mbps.
Audio format & Audio Bitrate only need to change if you have special requirement
Program name can be change to your specific requirement (Current HMDI-111. HDMI-112, HDMI-211,
HDMI-212)
Refer to manual re Service ID, FMT PID, Video PID, Audio PID, PCR PID, settings do not change unless
you fully understand their function.,
Program out enable A /B means that program will appear on A or B RF output, in the case of HMT-402

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 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 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, 3rd 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
