Page 3: General
1. General The CV-M2 is a digital 2 megapixel camera designed for automated imaging and ITS (Intelligent Traffic Systems) applications, featuring high resolution and high speed within a uniform and compact housing. The high-speed shutter function, asynchronous random trigger mode and partial scan mode allows the camera to capture high quality images of fast moving objects with a high frame rate. -

Page 8: Functions And Operations
6. Functions and Operations In the following the format shown in “7.5. CV-M2 command list” are used for function commands and parameters. 6.1. Basic functions The M2 camera is a progressive scan camera with 10 or 8 bit video output in single or dual channel Camera Link. -
Page 9: Restart Continuous Trigger Mode
6.1.3. Restart continuous trigger mode The RCT mode makes it possible to use a lens with video controlled iris for intelligent traffic surveillance applications. TR=2. The camera is running continuously, and the iris is controlled from the iris video output. When a trigger pulse is applied, the scanning is reset and restarted, the previous signal is dumped with a fast dump read out, and the new triggered exposure is started. -

Page 15: Lval Synchronous Accumulation
6.2.7. LVAL synchronous accumulation With LS=0, the accumulation will start synchronously with LVAL. The trigger pulse should be longer than 2 LVAL intervals, and the accumulation will then start at the first LVAL after the trigger leading edge. The exposure start delay will be up to 1 line. (Single channel 47.9 µsec. Dual 27.3 µsec). -
Page 16: Lval A-Synchronous Accumulation
6.2.8. LVAL a-synchronous accumulation With LS=1, the accumulation will start immediately after the trigger leading edge. The exposure start delay will be 156 clk. pulses after the trigger. It is 3.9 µsec. In EPS mode the exposure stops 0.5 L after the selected shutter time, (in number of LVAL). In PWC mode the exposure stops 0.5 L after the trigger trailing edge. -
Page 17: Partial Scanning Vertical Timing
6.2.9. Partial scanning vertical timing Partial scanning has 3 pre-selected vertical centred areas 1/2, 1/4 and 1/8. SC=1 through SC=3. With SC=3, the start and the height of the partial scanned area can be programmed with 1 line interval. The start line can be programmed with PS=1 through 1151. The scanned height can be programmed with PC=50 though 1200. -
Page 18: Input/Output Of Timing Signals
See the full connector pin assignment for Camera Link in chapter 5.3 and 5.4.5 For complete documentation on the Camera Link standard, please contact your JAI distributor. EEN is also found as a TTL signal on pin #9 on the 12 pin Hirose. EEN is low during exposure. -
Page 19: Continuous Operation (Non Triggered)
6.4.1. Continuous Operation (Non triggered) Mode settings can be done with RS-232C. Trigger Mode Normal. TR=0. It is for applications where the camera is continuously running without external trigger. The shutter mode can be normal or programmable exposure. (SM=0, SM=1). The shutter will work in all 10 steps up to 1/14,000 second or with the programmable exposure in 1216 steps. -
Page 20: Edge Pre-Select Mode
6.4.2. Edge Pre-select Mode In EPS mode, the trigger leading edge will start an exposure at the first LVAL pulse if LS=0, (or immediately if LS=1), and it stops and the resulting image is read out after the pre-selected shutter time. It can be the 10 steps in normal or 1216 steps in programmable. SM=0 or SM=1. This mode will operate with full and partial scanning. -
Page 21: Restart Continuous Trigger Mode
6.4.3. Restart Continuous Trigger mode The RCT mode is in principle the same as normal continuous mode. The difference is that an external trigger pulse will immediately stop the video read out and reset and restart the vertical timing. After a fast dump read out, a new triggered exposure is started and read out as normal. The fast dump read out is performed with a speed 18 times faster for single output, and 10 times faster for dual output. -
Page 22: Pulse Width Control Mode
6.4.4. Pulse Width Control Mode In PWC mode, the trigger leading edge will start an exposure at the first LVAL pulse if LS=0 (or immediately if LS=1). It stops at the trailing edge of the trigger pulse, and the resulting video is read out. -
Page 23: Burst Trigger Mode
6.4.5. Burst Trigger mode With the burst trigger function, a single trigger pulse can start a sequence with five previous set pre-selected programmable exposures. The five shutter times can be set with BSH1 through BSH5. (Exposure 1H through 1216H.) The exposure is LVAL synchronous. The sequence will start with the first exposure at the first LVAL pulse after the trigger leading edge, and the result is read out after the selected shutter time. -
Page 24: Piv Mode
6.4.6. PIV mode. PIV mode (Particle Image Velocimetry) can be used in applications where 2 images should be taken with a very short time interval. It can only be used with strobe flash as illumination. The first accumulation time is fixed at 4 µsec. After a delay >1.5 µsec. the second exposure period starts. -
Page 25: Sensor Gate Control
6.4.7. Sensor Gate Control This function is for applications with strobe flash illuminations or long time accumulations up to several frames. The resulting video is then read out after the first FVAL (or SG), following the trailing edge of the Sensor Gate Control signal. The sensor gate control signal can be synchronized by the FVAL signal. -

7. Configuring the Camera 7.1. Mode setting SW1 on rear Switch SW 1.1 on the camera rear can be used to select digital or analogue video out. SW1.1 has higher priority than RS-232C. SW1.2 is for termination of the trigger 1 input on pin #10 Hirose. (SW1.3 is for termination of the factory test input on pin #11 Hirose) SW1.4 is for master gain selection. -
Page 28: Rs-232C Control
7.4. RS-232C control All configuration of the CV-M2 camera is done via the RS-232C port on the 12 pin HR connector or via Camera Link. The control mode can be selected by the internal switch RS-232C/Camera Link. The camera can be set up from a PC running terminal emulator software, or using JAI´s camera control software. -
