CV-L105 1. Gener al The CV-L105 is a high-speed 3CCD color line sc an camera with 2048 pixels resolution. It features digital LVDS RGB output with 30 MHz pixel rate, allowing l ine rate up to 14285 lines/second. An exposure control function facilitates constant exposure time, independent of the scan rate.

Signal Remarks 1 NC 2 NC 3 GND Power GND 4 GND Power GND 5 NC 6 +12V DC in + Power in The camera connector part number is Hi rose H10A-7R-6P. (Male). The mating connector to use on the cable side is Hirose HR10A-7P-6S 5.
CV-L105 5.4. Input and Output Circuits Video outputs, timing outputs, trigger input an d control inputs are found on the 68 pin LVDS connector. 5.4.1. Video output The digital EIA-644 LVDS output is c.
CV-L105 5.4.2. Trigger input The camera is triggered by an EIA-644 LVDS input signal pai r. (+EXT TRIG in/ -EXT TRIG in (on pin #19 and pin #53)). Depending on the configuration of t he camera, this input can prov ide operation in 4 modes: Internal Trigger.
CV-L105 6. F unctions and Oper ations 6.1. Principle of operation A line scan camera works according to the same principle as a fax ma chine, also sometimes referred to as a “push broom” oper ation.

CV-L105 6.2. Trigger modes Internal Trigger. Scan mode. The camera will operate continuously with its internal trigger. LEN Data out Exposure Exposur e t i me = SCAN val ue LEN Data out Exposure Exposur e t i me = SCAN val ue The exposure is equal to the scanning time set by the SCAN parameter via RS-232C only.
CV-L105 6.2.1. Internal T rigger. Scan mode. In this mode, the camera does no t require an EXT TRIG signal to be issued to the c amera. The line rate (scan rate) is generated inside the camera. The camera will operate continuously with its internal trigger.
CV-L105 6.2.2. Internal Trigger. Shutter mode. In this mode, the camera does no t require an EXT TRIG signal to be issued to the c amera. The line rate (scan rate) is generated inside the camera. The camera will operate continuously with its internal trigger.
CV-L105 6.2.3. External Trigger . Scan mode. In this mode, the camera requires an EXT TRIG signal to be issued to the camera. The trigger signal is typical taken from an e ncoder. The exposure time is equal to the trigger interval. On the EXT TRIG input positive going edge the ongoin g integration peri od is terminated and charge is read out.
CV-L105 6.2.4. External Trigger. Shutter mode. In this mode, the camera requires an EXT TRIG signal to be issued to the camera. The trigger signal is typical taken from an e ncoder. The sca nning time is equal to the trigger interval. The exposure time is equal to the trigger low period (pulse wid th).
CV-L105 6.3. Other functions 6.3.1. Binnig Binning is a function where the signal from t wo neighbour pixels are ad ded and read out as a single pixel. The sensitivity will be double, but the resolution will be t he half. The binning function has no influence on the internal scan rate and shutter setting.
CV-L105 7. Configuring the Camer a All configuration of the CV-L105 ca mera is done via the RS -232C port, which is factory setting. Binning and pixel rate settings can also be cont ro lled by TTL signals into the interf ace connector or internal jumpers.
CV-L105 - 16 - Fig. 18. Shutter window 7.1.1. Clock Select With Clock Select two speeds can be selected, 15 MHz or 30 MHz . The 15 MHz operation will limit the maximum li ne rate (scan rate) to 7 172 Hz. It is recommended when a cable length of more th an 20 metres is used or in applications where high RFI fields may be experienced.
CV-L105 7.1.6. Gain and offset adjustment Fig. 19. Gain and Offset window The individual gain and offset setting of each co lor is possible. This is required for adapting the white balance temperature for the 4 user config uration are as. For the factory default this setting has no function.
CV-L105 7.2. Configuration via I/ F connector and jumpers The binning function, pixel rate and RS-232C function can b e controlled by TTL inputs on the 68pin Hirose interface connector and with jumper settings. Below table describe the possible states of these inputs.
