Setup Notes
Interfacing with a Control System
The unit may receive iCC-Net command strings from a Display Express server PC or a third-party control processor. The command strings
may be received at the following interfaces.
•
TCP at port 2728
•
RS-232 via the DB-9 port
•
RS-232 via either USB virtual com port
Only one TCP socket is supported. The buffered data bus allows for commands to be received concurrently from any of the interfaces.
Display Express Lite
The ICE-HE-DXL includes an embedded web server that hosts the Display Express Lite web page. Display Express Lite supports basic control
of power, volume, and channel selection for any combination of up to 128 display controllers, tuner/controllers, or IPTV
decoder/controllers. The web page may be accessed from the web browser of a connected device either wired or through a Wi-Fi access
point.
IP Network Settings
The IP Address, Default Gateway, and Subnet Mask may be set in the front panel Network menu or via RS-232 command. The current IP
address may be displayed on the front panel by holding the Setup button. The default IP address is 192.168.1.251. Changes to any of
network settings require a power cycle or reboot.
RS-232
The DB-9 RS-232 port may be used for control, configuration, and firmware updates. The baud rate settings apply to the DB-9 RS-232 port
and the rear panel USB virtual com port. Baud Rate settings are available in the front panel System menu or may be changed via RS-232 or
telnet serial command. The default baud rate is 19,200. Changes to the baud rate setting is instantaneous and no power cycle or reboot is
required.
USB Virtual Com Ports
The front and rear panel USB virtual com ports may be used for control, configuration, and firmware updates. Windows 10 will
automatically load the appropriate driver. The baud rate setting applies to the rear panel USB port. The baud rate for the front panel USB
port is fixed at 115.2K.
UDP Control
The iCC-Net commands that are transmitted via the RF output may be duplicated and transmitted as UDP directed broadcast data packets
for control of QIP-D and QIP-DVX IPTV decoder/controllers and 232-ATSC 4i and ATSC-SDI 4i HDTV tuners. This function may be enabled or
disabled in the front panel menu or via RS-232 command. It is enabled by default.
I/O Port
Inputs may accept a 0-24 VDC control voltage or contact closure to ground. A closed contact closure creates a logical low, an open contact
closure creates a logical high.
Outputs are open collector and may require a pull-up resistor; 28 VDC max, 200 mA max. A logic level high turns on the transistor and
creates a current path to ground.
