78 Chapter 5 Working with Images
Downloading bitmap images from a PCMCIA card
This section describes how to store a bitmap image on a standard PCMCIA memory card,
and then load the image as you would a built-in image. The generator can load only one
image from a card. Although you can download an image using VGM, loading an image
from a card is faster and easier.
This feature is supported on 802BT and 802R generators with video board FPGA 91 or
later, DVI daughter card FPGA 0xE3 or later, and firmware 7.3834000 or later (802BT) or
7.38180000 or later (802R). To determine your generator specifications, “ Displaying
system information ” on page 44.
To copy an image onto a card:
1. Save the image you want to store on the card as an 8-bit or 32-bit (24-bit TrueColor)
bitmap (.bmp) file on your computer using any file name.
2. Hold down the ACS , DCS , and DSS keys, and then cycle the power to the generator.
This removes any special modes and sets the baud rate of the serial port to 2400 bps.
3. Establish a terminal session with the generator and change the baud rate of the
generator to 38400 bps (see “ Changing the baud rate ” on page 15.)
4. Insert a PCMCIA card into the slot in the generator.
5. At the R:> prompt, enter the following command to initiate the YMODEM-BATCH
file-upload protocol:
YMDI
6. At the R:> prompt, transfer the file to the card. For example, to transfer a file using
HyperTerminal, do the following:
a. On the Transfer menu, click Send File . The Send File dialog box appears.
b. In the Filename box, click Browse and select the bitmap file you want to copy to
the generator.
c. In the Protocol box, click the down arrow and select Ymodem .
d. Click Send .
Note: You must send the image within about 15 seconds after sending the YMDI
command. If the R:> command prompt appears before you send the image, send the
YDMI command again, and then send the image again.
For descriptions of any error codes displayed, see Appendix C, “ Error Messages .”
To view an image stored on a PCMCIA card:
1. Insert the card that contains the image you want to view.
