Thank you for purchasing the Luxi Electronics® THB-350 scaler
transmitter. Please read through this manual before using the
product.
How the product functions:
To use the 2
nd
video output for
remote locations, this product needs to be connected to a Luxi
RHB-350 or a compatible HDBT receiver with POC or POE
turned off; failure to turn it off may cause damages and void warranty. Please refer to the “Video signal
path” and “Audio signal path” sections in the right column of the specs on page 5 for details.
Power options:
This product draws power from an external 24 V power supply sold separately (Luxi P/N
69-008-01). Do NOT plug the power supply connector into any other connectors; this could cause
permanent damages to the product and void the warranty.
Captive screw plug termination:
The captive
screw plugs for power, audio, RS-232 and
contact controls are supplied with the unit.
Separate the wires about 1” (2.5 cm)
long; strip off the wire insulation precisely
3/16” (5 mm) from the end. Identify the
positive and negative leads for power; Luxi
power supply has a white stripe on the
positive wire. If not sure, use a multi meter
to verify.
Mounting options:
Luxi has the under desk mount (Luxi P/N 78-002-01) or the MediaHub table tanks
sold separately; the product also fits many other mounting hardware from Extron, Middle Atlantic, etc.
Only use the type 4-40, 3/16” (5 mm) long screws supplied with the mounting hardware to screw onto
the product. Wrong type of screw could strip the threads; too long screw could touch and short the
internal circuit, cause permanent damages to the product and void the warranty.
Control options:
When auto switching off, pressing the “Input Sel.” button on
the front panel will toggle thru the 3 video inputs. 3 sets of external contact
closure push buttons and LEDs can select inputs discretely with the LED
indication, see wiring diagram on the right side; when a button is pressed, the
associated LED would blink once, then stay on. A RS-232 host connected to
this or RHB-350 can control all functions, see page 3 for the RS-232
commands.
