Analog Video Back Panel I/O Module Pin Connectors (P-32×32V shown) Signal Data Rate Switching Point Panacea analog video routing switchers are capable of switching composite and component analog video RF, IF, and other signals within the amplitude and bandwidth limitation. The Panacea analog video routing switcher has a sync input on the rear panel. A video reference signal can be fed to this module so that synchronous switching can be achieved. It is possible for the user to set a variable time delay before the switching is made so that critical switching will occur at the proper interval. The sync signal can be NTSC or PAL. Monitoring and Control The Panacea analog video routing switcher can be monitored and controlled through any one of various means. It can be controlled locally via the front panel control option or remotely via serial, X-Y, or Ethernet with a variety of software packages, including RouterWorks ® , Navigator, and Pilot. The various monitoring and control options provide a means to manage the switching of video and/or audio signals through this product as well as communicate the status of the input and output signals. The monitoring/alarm capabilities of this product enable you to act accordingly as the result of an alarm condition, should one arise. See page 63 for alarm configuration details. Power Conversion and Distribution The external power supply converts 100VAC through 240VAC to +15VDC, which is then supplied to the MI module. The +15V is applied to DC-DC converters, which will produce the +5V and +3.3V rails required by the core routing module. A green LED on the front of the logic control module indicates that power is present in the Panacea frame, but does not guarantee that all rails are present and within required voltage limits. 22 Panacea Series Frame and Modules Installation, Configuration, and Operation Manual

Control and Communications Signal Path Signal Flow Configuration Information Installation Information Chapter 1: Introduction The logic interface circuit allows the Panacea analog video routing switcher module to communicate with the Panacea system controller. In addition to addressing the crosspoint matrix, the logic interface circuit also provides the system controller with information about the system status. Matrix size, module type, firmware revision level, input signal presence, and other information is provided to the system controller through the logic interface. Information about the core routing module can be viewed with a terminal or computer connected to the Panacea system controller via the serial port. Each signal path consists of an input buffer, crosspoint matrix, and output drivers. The input buffer provides an excellent return loss. The 16×16 analog video crosspoint IC supplies the matrix (single in 1RU, 4 in 2RU). The driver amplifier delivers analog video to a 75Ω coaxial cable. Figure 1-19 shows a signal flow diagram for the analog video routing switcher. Figure 1-19. Signal Flow Diagram of the Analog Video Routing Switcher The analog video module requires no additional procedures for configuring DIP switches and the alarm port beyond those described for frame configuration. Frame DIP switch and alarm port configuration is described on page 62 – 68. All internal modules are installed at the manufacturing facility.
