TS-2030EN/TS-2076EN Series Progressive Scan Cameras
Camera Features
(address=107) and Camera RS-485 address registers (address=109). Thus it is possible to send a serial RS-485
trigger to any or all of the cameras. RS-485 communication is accessed via the 26-pin connector on the rear
panel of the camera.
RS-485 is typically used by the lane controller to send serial trigger or to send DatalD message to validate the
HW TTL trigger.
RS-485 is a differential signal communication for longer distance. Since RS-485 is not a common port for PCs,
a plug-in 485 board such as ULTRA-485 (Industrial Computer Source, San Diego, CA, 800-523-2320) or
compatible is required.
6.5.2 Ethernet
The primary benefit of Ethernet is the scalability of the system; you can add as many EN cameras as you want to
the system. For example, you can connect up to 255 Ethernet devices to one class A subnet. Command/Status
register access and image transfer are securely done over TCP/IP protocol. In addition to the message-based TCP
image transfer, sniffing image on UDP is also supported. Captured images are buffered inside EN camera, and
can be automatically transferred to FTP server. Ethernet trigger can be used for applications where time critical
response is not required as hardware TTL trigger.
All functions over Ethernet are accessible by EN setup software. Please refer to VIS300/400EN Setup User's
Guide (Doc Number 4087-72-005).

Color Filter Array (Color Version)
The color filter array requires software to interpolate color. If the proper interpolation software is not present the
camera provides an 8-bit monochrome image. The necessary DLL is available from JAI Inc.. The JAI Inc.
TSC-2030EN/TSC-2076EN cameras use the Bayer color mosaic filter pattern (see Figure 16 below). The CFA
contains 50% green photo sites and 25% red and 25% blue photo sites.
FIGURE 16.
CFA Pattern
Because the color filter array contains only a single R, G or B color in each pixel, the restored image has to fill in
colors in the missing pixel locations. The software uses neighboring pixel information to "guess" the missing
colors to make smooth, clear images. This is called "color interpolation."
