14797 • November 2004 • Introduction/Overview INTRODUCTION/OVERVIEW The S5000 Signal Management System provides an economical yet extremely versatile platform for signal distribution and processing tasks. Separate left and right passive rear backplanes permit differing tasks to reside within the same frame. PRODUCT SCOPE The S5000 is shipped with (1) power supply and (2) backplane adapters.
14797 • November 2004 • Receiving Inspection and Unpacking RECEIVING INSPECTION AND UNPACKING By the time you have found and opened this manual, you have already begun to unpack the shipping container. Since damage may have occurred in shipping it is important to perform the following checks immediately: • Inspect the shipping container(s) for damage. • If you find any damage to the containers, carefully inspect the product for damage. • If any damage is discovered, notify the shipping carrier immediately.
14797 • November 2004 • Backplane Configuration BACKPLANE CONFIGURATION The S5000 can be easily reconfigured in the field if requirements change. Typically the rear backplanes need to be replaced to accommodate a different module loading. If you obtained the S5000 with no rear backplanes installed, or simply need to replace one refer to the steps and figure below. 1. Remove AC power connection(s) to the frame by disconnecting the line cord(s). 2.

14797 • November 2004 • S5000 Frame Description S5000 FRAME DESCRIPTION The S5000 Signal Management System (part number S5000) consists of a 2 rack unit (RU) high metal frame assembly that installs in a standard 19” wide equipment rack. The frame includes a built-in motherboard (EM0328) that provides module interconnections and a power distribution board (EM0326) for distributing power from the AC inputs to the power supplies.
14797 • November 2004 • S5000 Frame Description Frame Rear View Figure 4 illustrates the S5000 Frame rear view. The following list, which is keyed to the figure, explains the purpose of the connectors on the rear panel. Œ Video Reference Inputs: Analog NTSC or PAL looping 75 ohm reference video input. Not used with DA modules. • IEC Standard AC power connectors: Connect to AC power. Ž Alarms Connector: Open collector type power supply alarm outputs.
14797 • November 2004 • S5000 Frame Specifications S5000 FRAME SPECIFICATIONS Table 2 lists specifications for the S5000 Signal Management System. Table 2.
797 • November 2004 • Installing the Frame in a Rack INSTALLING THE FRAME IN A RACK To install the S5000 frame in an equipment rack, see Figure 5 and follow these steps: Warning: The power cords supplied with the S5000 provide the only means of AC mains disconnection. The equipment must be located near the AC source power outlet and the outlet must be easily accessible to allow power to the equipment to be disconnected quickly in an emergency. 1. Determine the placement of the 2 RU frame in the rack.
14797 • November 2004 • Installing the Frame in a Rack Frame Door Installation and Removal The frame door includes latches on both sides that must be pressed inward in order to remove the door. Caution: Be careful not to drop and damage the door when you release the latches. The latches are the only mechanism holding the door in place. When installing the door, just push the door onto the frame and the latches will latch themselves automatically.
14797 • November 2004 • Installing the Frame in a Rack Power Supply and Communication Interface Installation and Removal The Power Supply modules and Communication Interface install in the slots in the center of the frame. If you have only one power supply module, install it in the bottom center slot. The redundant supply installs directly above the main module. The Power Supply module has a latch similar to the latches on the frame front cover to ensure the Power Supply remains in place.
14797 • November 2004 • Installing Modules INSTALLING MODULES Before you insert the printed circuit modules into the frame, make sure you are using the correct I/O backplane. Table 3.

14797 • November 2004 • Making Connections to the Frame Alarm Connections The ALARMS connector includes normally closed connections from pin 1 and pin 2 to COM, which is connected to chassis ground. If both Power Supply modules fail (or AC is disconnected from both), the pin 1 to COM circuit opens. The alarm associated with pin 2 is reserved for future use. Figure 10 shows one circuit that can be used with the Alarms connector. It contains LEDs that are normally OFF and turn ON to indicate a failure.
14797 • November 2004 • Power Supply Module (PS5000) POWER SUPPLY MODULE (PS5000) The Power Supply module accepts and adjusts automatically to a wide range of AC input voltages (90-130/180-250 VAC, 50/60 Hz). Regulators on the module rectify the AC to produce +/- 7 and +/- 15 VDC which is distributed to the other modules in the frame. Figure 11 shows a block diagram of the Power Supply module.
14797 • November 2004 • Power Supply Module (PS5000) Power Supply Test Points There are four test points on the front edge of the power supply modules. When checking the test points, test both the main and redundant supplies. The approximate range of voltages that may be expected at these points is listed below. Voltages outside of listed ranges may indicate a bad power supply module; replace with a known good module. Table 4. Power Supply Test Points PS TEST POINT +7 -7 +15 -15 DC VOLTAGE RANGE +6.
14797 • November 2004 • Communications Interface Setup COMMUNICATIONS INTERFACE SETUP The CI5705 can be used to control operation of modules within the S5000 frame. This is accomplished via communications through a 9-pin D-subminiature connector located on the back of the unit labeled NTWK EIA-485. Communications to the S5000 must adhere to the RS-485 or RS-422 communications protocol. The NTWK EIA-485 connector on the rear of the S5000 utilizes the pinout detailed in the table which follows. Table 5.

Frame ID Setting FRAME ID SW1 SW2 0 SW3 RESERVED 1 OFF ON ON 2 ON OFF ON 3 OFF OFF ON 4 ON ON OFF 5 OFF ON OFF 6 ON OFF OFF 7 OFF OFF OFF Depending upon the controlling device’s operating parameters, the CI5705 may need to have its communication speed changed. DIP switches SW4 and SW5 of S2 located at the front of the CI5705 card are used to set the communication speed as detailed in Table 6 belowTable 7.

14797 • November 2004 • S5000 System Theory of Operation S5000 SYSTEM THEORY OF OPERATION See Figure 12. The S5000 frame is a relatively simple system consisting of a metal rack frame, replaceable I/O backplanes on each side of the back of the frame, a power distribution board, and a motherboard. A variety of modules may be inserted into the frame as desired to create a complete signal distribution and processing system.

14797 • November 2004 • Maintenance MAINTENANCE The S5000 does not require any periodic electrical or physical maintenance. You may want to check the system’s indicators occasionally to ensure that the system is operating normally and to make sure cooling air flow through the fan in the front of the frame is unobstructed. Fuse Replacement Fuses are located on Power Supply modules. If a problem occurs on a module, the first thing to do is check the fuses. The following table lists the fuses: Table 8.
14797 • November 2004 • Troubleshooting TROUBLESHOOTING Many system troubles are caused by easily-corrected errors, such as poor quality or missing input or reference signals. Table 9 lists common problems and their solutions in approximately the most likely order of occurrence. Try troubleshooting the system yourself, and if you are not successful, call Sigma Electronics Technical Support, as explained near the front of this manual.
