Connect to a computer Figure 2-2: Wiring the 25-pin Remote Interface Connector You can connect to a computer via the 9400’s serial connector or via an Ethernet network. You must have the 9400 PC Remote application installed on your computer before you upgrade your 9400’s firmware because 9400 PC Remote manages the upgrade. See Networking and Remote Control on page 2-47, Appendix: Setting Up Serial Communications on page 2-59, Installing 9400 PC Remote Control Software on page 2-51, and Using the 9400 PC Remote Control Software on page 3-61 for more detail.

OPTIMOD-AM DIGITAL INSTALLATION 2-5 8. Install Monitor Rolloff Filter. (optional) Orban Monitor Rolloff Filters are accessories that can be ordered from your authorized Orban Broadcast Dealer. The Orban model number is MRF-023. The Orban Monitor Rolloff Filter alters the flat response typical of a modulation monitor's audio output to one that more closely resembles that of an actual AM receiver. It is a passive filter, requiring no power supply. Its metal flange is drilled such that it can be mounted to one rail of a standard rack. (See page 1-23 for more about studio monitoring.) A) Select rolloff response. The Monitor Rolloff Filter is supplied jumpered for NRSC WITH 10 KHZ NOTCH, unless otherwise noted. NRSC with 10 kHz NOTCH Accurately simulates the sound of a standard NRSC receiver. Also useful for remote off-air monitoring because it filters out the 10 kHz whistles caused by interfering first-adjacent stations (in countries with 10 kHz channel spacing). Intended to complement the HF CURVE NRSC setting in OPTIMOD-AM. Note that very few real radios have a frequency response resembling the NRSC standard. Therefore, the NRSC rolloff will result in substantially brighter sound than most radios provide, and the 18dB/OCTAVE setting provides a more realistic simulation of a typical radio. NRSC: NRSC rolloff without 10 kHz notch. 18dB/OCTAVE Simulates the sound of an average narrowband AM/MW receiver except that it shelves off above 6 kHz instead of continuing to rolloff as a real radio would. This rolloff complements an HF CURVE setting of 0 in Figure 2-4: Jumper Positions, Monitor Roll-Off Filter
