Remote Control Connection
There are three types of control ports:
• RS-232: Attach a null modem cable to the port. The default setting is 19.2K baud and can be changed via the front panel
setup.
• USB: Connect a mini-B USB cable from a Display Express PC or other control system. It shows up as FT230X UART in Win-
dows/Devices.
• Ethernet: Connect to an IP network port to access the internal DX Lite webpage, or use the port for telnet control or con-
nection to a Display Express server.
RF Coax and iCC-Net Operation
• Connect an RF coax feed from RF Out to the system's RF combiner, mixing the iCC-Net Out signal with the other CATV chan-
nels. The iCC-Net Out channel operates at 74.7 MHz, between cable channels 4 and 5.
• When combining the RF output with QMOD modulators, the internal attenuator should be set to 29 dBmV to match the
modulator's level. 29 dBmV is the factory default setting.
• Do not connect any feeds to RF In in normal operation. It is used only for legacy 2-way applications.
AC Power
• Insert the DC power supply plug into the Power In jack.
• Plug the power adapter into an AC wall outlet. The front panel display should turn on.
I/O Port
• Inputs are 0-24 VDC 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. Turning on the output turns on
the transistor and creates a current path to ground.
