FAQ
Tuning Cable
Channels
The 232-ATSC 4S will skip encrypted channels automatically when you activate a channel scan.
You can skip scanning analog channels by pressing
Select
after you start the scan.
Typically, the digital channels will not use the same Guide numbers as a cable box.
If you c
an’t select channels, make sure that the channels have been scanned.
RGB/Component
Video
Analog HD is output on either the RGBHV (VGA) or Component output. Use the front-panel
menu to select the desired output.
There can be “fluttery” lines at the top of
the analog video
–
this is closed captioning data.
Go to the Overscan menu and increase the value.
HDMI
HDCP is always off
–
not required for non-encrypted programs
If a monitor has issues with current resolution, 1080p/60 works best for newer models.
Composite Video
Press the RATIO button on the IR remote to select the desired format for NTSC video
The onscreen menu also has
Screen Format
settings, generally only used when tuning an analog
channel.
Audio
Volume won’t affect digital audio in AC
-3 or PCM modes, while PCM Variable supports level
control. If there is no audio, make sure the volume is all the way up (and not muted).
A “motorboat” sound means the source does not support AC
-3, change to PCM.
IR Control
There can be interference from room fluorescent lights. Hold down SELECT on the remote.
Pressing 4 selects normal 38 KHz IR, pressing 9 selects 57 KHz IR.
Check the front-panel R Receive menu to see if it is turned on or off.
If there is significant IR interference, an IR-RXC Remote Sensor may be required, and cover the
front-panel IR sensor to reduce interference.
RF Network
When the tuner is connected to the RF network and an IC-HE series interface has been installed,
the NET LED on the front panel will blink once per second, confirming the unit is receiving the
“heartbeat” command. If the NET light does not flash, check the RF connection at the ICE
-HE.
Control Codes
The tuner’s control type has been pre
-set at the factory when shipped. Once you connect the
source with an RS-232 cable, the Power button should turn the monitor or projector on and off.
There should be a label on the unit that states the current control type, or:
•
Use front-panel menu 50 to see or change the type
•
Use the IC-RC mode text menu
•
Send a T0 command to change the type
The control type sets the baud rate to a typical setting for the source, the rate can be changed
from the front-pane menu, or an R5 command over RF.
Device Address
If the tuner’s NET LED is flashing, but the TX LED does not flash when a command is sent fro
m
Display Express or a custom control system
–
it is likely not at the correct address. If an All Zones
command (4095) is sent, and the unit responds
–
the address is incorrect.
Check the settings via the front panel menu, or enable the IC-RC mode to display the current
setting using an IR remote.
