Model 628 Encoder Sensor Instruction Sheet

Installation

1.The Sense Input signal must

be a 1 Vp-p scrambled video sig-

nal. Connect the Encoder’s

scrambled video output to the

628’s Sense Input.

2. Connect your barker channel

to the Primary Input. This is

normally an IF signal.

3. Connect your Encoder’s IF

ouput to the 628’s secondary

Input.

4. Connect the Common output

of the 628 to your modulator’s

input.

5. Plug the power supply

provided into the 12VDC input

on the unit

Specifications

RF Isolation

> 60 dB @ 450 Mhz

Sense Input Level

1 V p-p Video ± 10 %

Levels below approximately 0.8

V p~p should cause secondary

to connect to the output.

Power Requirement

100-240VAC ±2%, 50/60 Hz.

Power pack output; +12 VDC

Physical

5.25” H X 2.75” W X 2” D

Operation

The 628’s sensing circuit moni-

tors the loss of scrambled video.

The absence of the scrambled

video causes the 628 to auto-

matically switch to the primary

input. It will remain in this state

until the scrambled video returns

to the sense input causing the

628 to switch back to the sec-

ondary input.
