Setup Information

This document provides installation and setup support only for the OAT100R. One or more VHF and/or UHF antennas must be installed before you proceed to set up the OAT100R. LG recommends that the system be professionally installed.

Check the following items before you begin the OAT100R installation and setup procedures.

VHF and/or UHF Antennas

__ Create a station plan for the OAT100R terrestrial input(s).

__ Install the appropriate antenna(s) in accordance with the desired channels. The VHF and/ or UHF antenna(s) must be located where it/they will have unobstructed access to the terrestrial signals. Amplify the antenna distribution as necessary.

__ Point the antenna(s) so as to achieve the best signal quality (use appropriate equipment for measurement purposes).

__ Up to eight 75 ohm RG-6 or larger coaxial cables from the terrestrial antenna distribution system should be available for connection to the OAT100R.

__ Confirm that the installation environment meets the >17 dB specification for the OAT100R RF input signal-to-noise ratio.

__ Measure the signal level at each of the OAT100R RF inputs. For proper system performance, the signal level at each RF input must be between +3 dBm (+52 dBmV) and -83 dBm (-34 dBmV). A nominal value of -53 dBm (-4 dBmV) is recommended. Note that additional equipment (i.e., attenuators) may be required to adjust the signal level.

OAT100R

__ Unpack the OAT100R unit and all accessories.

OAT100R Accessories: • AC Power Cord and Adapter

__ Select the location for mounting the OAT100R. Ensure that adequate ventilation is available.

__ Obtain the necessary attachment hardware to mount the OAT100R chassis in its targeted location.

__ Plan and install the necessary cabling and network (Ethernet) and AC power access for the OAT100R. You will also need the following to connect a PC directly to the OAT100R for system setup purposes: FTDI TTL-USB cable (P/N TTL-232R-5V-AJ).

Channel Assignments for RF Output

__ Create a channel assignment plan for the installation site, or modify an existing plan to incorporate the RF output of the OAT100R. Ensure that up to four contiguous CATV broadcast channels are allocated for the OAT100R RF output. The OAT100R uses either a 256-QAM or 64-QAM modulation format, thereby occupying approximately 24 MHz of frequency spectrum.

The RF start channel is user-assigned during system setup, and the remaining channels are then automatically assigned per EIA-542 STD CATV frequency allocation standards. For example, if the RF start channel assignment is channel 2, the three remaining channels
