Manual Overview

The Sencore Tech Tips manual #185 provides detailed instructions for programming sync timing parameters into the CM2125, focusing on troubleshooting, error codes, diagnostics, and adjustments. The manual outlines a nine-step process to enter timing parameters, such as horizontal and vertical frequencies, resolutions, and porch and sync times, into the CM2125. These parameters are crucial for synchronizing monitor displays, ensuring correct picture size and centering. Troubleshooting guidance includes recognizing error codes like “E 4” and “E 9,” which indicate issues with vertical sync frequency settings and unenabled sync time programming mode, respectively. Calibration involves entering specific keystrokes to adjust timing parameters, which are stored in nonvolatile memory locations 43-69 for future use. The manual also explains how to recall and verify stored parameters, with limitations on accessing setups in memory locations 0-42. Proper programming ensures the display is correctly aligned, avoiding issues such as shifted or improperly sized images.

Quick Issues Covered

• Diagnose 'E 4' error for incorrect vertical sync frequency setting.
• Resolve 'E 9' error by enabling sync time programming mode.
• Adjust sync timing to fix display size and centering issues.

Operation

The CM2125 can be programmed with specific timing parameters for a computer monitor. To program the device, follow these steps:

1. Set the horizontal frequency to 65.2 kHz and horizontal pixels to 1024. Set the vertical frequency to 61.7 Hz and vertical pixels to 1024.
2. Enter the “scan time” program mode by pressing STORE, 8, 0, and ENTER.
3. Program the vertical front porch by pressing STORE, 8, 1, ENTER, and entering the time value.
4. Program the vertical back porch by pressing STORE, 8, 2, ENTER, and entering the time value.
5. Program the vertical sync by pressing STORE, 8, 3, ENTER, and entering the time value.
6. Program the horizontal front porch by pressing STORE, 8, 4, ENTER, and entering the time value.
7. Program the horizontal back porch by pressing STORE, 8, 5, ENTER, and entering the time value.
8. Program the horizontal sync by pressing STORE, 8, 6, ENTER, and entering the time value.
9. Store the setup in memory location 50 by pressing STORE, 5, 0, and ENTER.

The timing values can be checked by recalling the stored location. The CM2125’s memory is nonvolatile, so the setup will not be lost when the unit is turned off.
