The HCS7720 contains several internal registers for different configuration options. There
are two methods available for configuration purposes:
• Service Port Method
• Controller Card Method
This document describes configuration procedures using the Service Port Method, which
requires that you connect a PC directly to the transcoder Service Port. For configuration
procedures using the Controller Card Method, refer to the Installation & Setup Guide for the
feature card installed in the card frame CONTROLLER slot.
Note: Before you proceed with any additional configuration, the ViP 222k
satel lite receiver(s) and the HCS7720 card(s) should be installed and operating
as described in the Installation and Setup sections in this manual.
Connect a PC to the HCS7720 Service Port
Connect the PC to the HCS7720 Service Port using the FTDI TTL-USB cable (P/N TTL-
232R-5V-AJ):
• Plug the USB end of the cable into an open USB port on your PC. If necessary, install the
device driver.
• Plug the other end of the cable into the Service Port jack on the HCS7720 front panel.
Access the HCS7720 Main Menu
1. Using HyperTerminal or an equivalent terminal emulation program on the PC, configure
the serial port as follows:
• Bits per second/baud = 115200
• Data bits = 8
• Parity = None
• Stop bits = 1
• Flow Control = None
Then, initiate communication with the HCS7720.
2. Press Enter to refresh the menu display in the terminal.
You now have access to the HCS7720 configuration Main Menu (see example on following
