Integrated L-Band Up/Dn Converter LT3600 CG-1309 SECTION 2 Installation 2.0 INTRODUCTION 2.4.1 Power Input This section defines the installation requirements by which the Integrated L-Band Up/Dn Converter will meet the published specifications. This connector is an IEC 320-C14 male and will accept any compatible mating connector. The power cord supplied as standard with the unit is equipped with a NEMA 5-15P male plug at the opposite end and is compatible with most 115 VAC supplies.
Integrated L-Band Up/Dn Converter LT3600 2.4.6 External 10 MHz Input (J2) This connector is a BNC female. The male mate (not supplied) should be compatible with the 50-ohm coax used to connect to the system. 2.4.7 SSPB Interface (J6) This connector is a 9-pin female miniature type “D” connector with standard #4-40 female screw-lock hardware mounting. The mating shell, pins, and strain relief are not supplied. Outputs are open collector and inputs have internal 1K full PS to +5V.
Integrated L-Band Up/Dn Converter LT3600 CG-1309 SECTION 3 Operation 3.0 INTRODUCTION The Up/Down Converter can be controlled from the front panel or remotely via a serial bus located on the rear panel of the converter. Various menus are available for EDIT and DISPLAY purposes. See Figure 3-2 for a listing of the menus. Section 4 gives a complete description of the bus commands and conventions for operating the converter remotely.
