1. Product description
The devices are transmodulators with two DVB-S/S2/S2X (tdx420C, tdx420), DVB-T/T2/C (ttx420C, ttx420) input channels
and two DVB-T/ISDB-T output channels. The devices are designed for digital transmodulation with Transport Stream
Processing of TV or Radio programmes issued from FTA (Free to air) or encrypted digital reception; in case of encrypted
signal, the CAM (Conditional access module) containing the operator's smart card must fitted in the slot. Modules processor
enables, services filtering, modifying SI (Service Information), generating NIT (Network Information table), LCN (Local Channel
Number), restamping PCR (Program Clock Reference). All of the configurations can be changed by using the Web Interface.

2. Safety instructions
Installation of the transmodulator must be done according IEC60728-11 and national safety standards.
Any repairs must be made by skilled personnel.
Do not expose this transmodulator to moisture or splashing water and make sure no objects filled with liquids, such as
vases, are placed near or on the unit.
Avoid placing the transmodulator next to heat sources such as central heating components or in areas of high humidity.
Keep the transmodulator away from naked flames.
If the transmodulator has been kept in cold conditions for a long time, bringing it into a warm environment may cause
condensation, so allow it to warm up for no less than 2 hours before powering.
Ventilation should not be impeded by covering the transmodulator, such as newspapers, table-cloths, curtains etc.
Mount the transmodulator in a vertical position only. If installing in a 19” rack system additional forced air cooling fans
may be required (see table "Technical specifications" - operating temperature range).
Always allow 10 cm of free space from the top, front and bottom of the unit to enable any heat to be dissipated.
