Page 41: A12 Main Board
Theory of Operation This section describes the basic operation of the major circuit blocks or modules in the MTX100A. The Diagrams section, beginning on page 6-1, includes a block diagram and an interconnect diagram. A12 Main Board The A12 Main board consists of the following blocks: PCI Interface The PCI interface consists of a PCI target and a PCI master.
Page 42: A20 Pci Backplane Board
The interrupt controller sends the following interruption signals to the CPU: Play FIFO empty, Record FIFO full, external trigger, 10 Hz, Playout DMA transfer finished, and Record DMA transfer finished. These interruptions can be disabled by the MTX100A application software. At power on, all interruptions are disabled. TS Clock Generator The TS clock generator consists of a VCO (Voltage Control Oscillator), phase detector, frequency divider.

Preventing ESD When performing any service which requires internal access to the MTX100A, adhere to the following precautions to avoid damaging internal modules and their components due to electrostatic discharge (ESD).
Page 109: Inspection And Cleaning
MTX100A is used. General Care The cabinet helps keep dust out of the MTX100A, and is needed to meet EMI and cooling requirements. The cabinet should be in place when operating the MTX100A. The front cover protects the front panel and display from dust and damage.
Page 110: Table 4-1: External Inspection Check List
Cleaning Procedure — Exterior. To clean the MTX100A exterior, perform the following steps: 1. Remove loose dust on the outside of the MTX100A with a lint free cloth. 2. Remove remaining dirt with a lint free cloth dampened in a general purpose detergent-and-water solution.
Page 111: Table 4-2: Internal Inspection Check List
Maintenance Inspection — Interior. To access the inside of the MTX100A for inspection and cleaning, refer to the Removal and Installation Procedures in this section. Inspect the internal portions of the MTX100A for damage and wear, using Table 4-2 as a guide. Defects found should be repaired immediately.
Page 112 STOP. If, after performing steps 1 and 2, a module is clean upon inspection, skip the remaining steps. 3. If steps 1 and 2 do not remove all the dust or dirt, the MTX100A may be spray washed using a solution of ethyl alcohol by performing steps 4 through 8.
Page 113: Removal And Installation Procedures
WARNING. Before performing this or any other procedure in this manual, read the Safety Summary found at the beginning of this manual. Also, to prevent possible injury to service personnel or damage to components of the MTX100A, read Installation in Section 2, and Preventing ESD in this section.
Page 114: Table 4-3: Summary Of Procedures
First read over the Summary of Procedures that follows to understand how the procedures are grouped. Then read Equipment Required for a list of the tools needed to remove and install modules in the MTX100A. If you are removing a module for service, begin by performing the procedure Access Procedure (page 4-14).
Page 115: Table 4-4: Tools Required For Module Removal
Removal and Installation Procedures Required Equipment. Most modules in this MTX100A can be removed with a screwdriver handle mounted with a size T-10 Torx screwdriver tip. Use this tool whenever a procedure step instructs you to remove or install a screw unless a different size screwdriver is specified in that step.
