Comments
• 1354SHOW cannot show a greater color depth than the display allows.
• The PC must not have more than 12M bytes of system memory when used with the
SDU1354B0C board.
• Follow simultaneous display guidelines for correct simultaneous display operation.
• To determine if the CRT will operate correctly when using a dual panel, refer to the “Maximum
Frame Rates” table in the SED1354 “Functional Hardware Specification,” document number
X19A-A-002-xx.
• When editing in 1354CFG with CRT enabled and panel disabled, select “Single Panel” from the
“Edit Panel Setup” submenu.
• When a CRT is enabled, the CRT settings will override the panel settings. If a panel is also used,
the CRT timing values will have to be changed to more closely match the panel's timing.
• A CRT cannot show 15 or 16 bits-per-pixel.
• Do not attach a panel with a 16-bit interface to the SED1354 when a CRT is also attached.
Program Messages
ERROR: Too many devices registered.
There are too many display devices attached to the HAL. The HAL can only manage 10 devices
simultaneously.
ERROR: Could not register SED1354FOA device.
A 1354 device was not found at the configured addresses. Check the configuration address using the
1354CFG configuration program.
ERROR: Did not detect SED1354.
The HAL was unable to read the revision code register on the SED1354. Ensure that the SED1354
hardware is installed and that the hardware platform has been set up correctly.
