An API (application program interface) for Windows is available. Using an API, the time required to develop software for device discovery, command communication, and image transfer can be shortened. Please contact JAI Inc. for further information.

6.9Image Buffering

Full size TIF images, JPEG images, and ODD/EVEN field images are independently managed in image buffers. Each buffer is a sequential image queue. When the index reaches the last image, the user can select either to overwrite the oldest image (or the first image), or to stop writing. Also, the user can set the depth of the queue and the size of the JPEG image, while TIF, and ODD/EVEN field image sizes are fixed. These image queue buffer operations are done using EN setup software by accessing the "Storage Setup" command.

As a factory default, the image size and queue depth are defined as the following;

Table 10	Factory Default Storage Setup of Image Buffering
Parameters	9720	9720	2030	2030	2076	2076	1327	1327	4032	4032
	(BW)	(Color)	(BW)	(Color)	(BW)	(Color)	(BW)	(Color)	(BW)	(Color)
TiF queue size	20	25	15	20	10	13	15	15	20	23
JPEG size	20	0	15	0	10	0	15	0	20	0

Please refer to the "EN-to-LC Interface Document" for more information.

6.10 FTP

FTP (File Transfer Protocol) is the industry-standard file transfer protocol. All EN cameras have an FTP client built-in. TIF image, JPEG image, or both can be transferred to the FTP server automatically.

FTP server's IP address, username, password, and subdirectory name must be properly set by FTP command. Additionally, a 2nd FTP server is supported in case the 1st FTP server is accidentally down. Please refer to the “EN-to-LC Interface” document for the FTP command.

Additionally, the FTP server must be properly set up. Make sure to create a username and password, and to allow read/write/modify access so that the EN camera can write image files in the sub- directory of the FTP server's hard disk. FTP server's hard disk must be regularly cleaned up, otherwise hard disk capacity becomes full and EN camera cannot write image files.

The default FTP port is 21, but the user can change this port number. Please refer to the Troubleshooting section for various FTP server performance tests.
