To e nable y our A dtec E N-series d evice f or A SI R eceive M ode, f ollow t he f ollowing s teps:
Step
Action
1
On t he r ear p anel o f t he d evice, c onnect y our A SI c able t o t he " ASI-IN" B NC
connector.
This i s a s hared c onnector; i t a lso f unctions a s t he S DI-In c onnector.
2
Access t he W eb U I f or y our u nit.
3
On t he " Video" t ab, s elect < On> a s t he o ption f or " ASI R eceive M ode".
This r outes t he A SI s ignal t o t he u nit's i nternal m odulator.
4
On t he S tatus D isplay o n t he L CD P anel ( unit f ront p anel), " ASI R eceive/Passthru"
should b e s hown.
