Description and connections

The module ETWF 310 is used for the reception of two base band channels (A/V).

Each module allows the modulation of both base band input signals in a multiplex DVB-T (COFDM).

A feature of this equipment is its modulator in Vestigial Side Band (or VSB). This modulation can be used to distribute

adjacent channels in one distribution without any intermodulation problem.

Each module has one Loop connector to cascade several modules at input and a Mix connector to do same in output

channels

.The output channel is selectable between C2 and C69.

All parameters are programmed by the means of PRO 201 or the EVO or MINI series of field strength meter, and they are

monitored in the display of programmer or in the 5” TFT screen of field strength meter.

ETWF 310

1. Two-colored led*: It indicates the different states of the device.

2. OUT: This connector supplies the modulated channel according to the

selected standard in the module and mixes it with all the signals that it

receives through the MIX connector

3. MIX: Input of mixing of the module.

4. L1/R1: RCA audio inputs (channel 1).

5. L2/R2: RCA audio inputs (channel 2).

6. RS 232: Ethernet connector to cascade modules with the RCM 310

telecontrol unit with the RJ45/RJ45 cable provided.

7.PRO 201: Ethernet connector to make the programming with the

programmer.

8. Video 1/Video 2: RCA video inputs (channel 1 & 2).

9. DC connectors: It has two connectors for input/output.

*States of two-colored leds

1. Initialization mode

- Green: main application charged.

- Blinking Green: Completing the initial sequence, at the moment when the module gets initialized, the led will turn

into one of the states the operating mode.

- Red: Phase of initializing the module.

2. Operative Mode

- Green: The system is working properly.

- Orange: At least one critical event has been recorded in the module. The led will only change into green when

the registration of events has been read by the programmer.

- Red: Error or alert detected in the running of the device, the led will be on only as long as the error/alert is

present. Once the error or the alert disappears, the led will change into orange because the error/alert is stored in

the registration of events.

3. Programming mode

- When the module detects an external programmer, the led will blink in the next sequence: green-orange-red.

- Once you leave the programming mode, the led will turn into the corresponding operating mode.
