Page 7: Introduction
• High sensitivity The TM-250 camera is one of the most low-light sensitive 1/2" CCD cameras available today. This feature is especially important when using the faster shutter speeds. The CCD detects images into the near-infrared spectrum. It requires only 1.0 lux of minimum illumination and 0.5 lux minimum illumination at maximum gain. -
Page 8: Functional Options
Image capture can begin within a second after turning on the camera. The power consumption is only 2.5W. This makes the camera excellent for use with battery-operated systems. • Camera-mounting flexibility The TM-250 has tapped holes on all four sides to allow a tripod mount to be installed from any angle. • Three-year warranty The CCD solid-state image sensor allows the camera to maintain a superior performance level indefinitely while requiring virtually no maintenance. -
Page 9: Applications
Introduction 1.4 Applications The miniature size of the TM-250 camera eliminates the need for a remoted imager camera in all but the most confined spaces. This camera fits easily, both physically and functionally, into all types of machine vision, automated inspection, and related applications. Other uses include remotely piloted vehicles, miniature inspection devices, surveillance, microscopes, and medical equipment. -
Page 10: Installation
2.2 Camera Setup 2.2.1 Connector Pin Configurations The TM-250 has a 12-pin connector for power input. In general, Pin #1 is Ground and Pin #2 is +12V DC. The other pins handle a number of other input and output functions, as shown in the table below. -
Page 11: Power Supply And Power Cable
2.2.2 (b) PULNiX Power Cables If you are using PULNiX power cables, such as the 12P-02S, please refer to the appropriate pin-out diagram. The color coded leads use Gray for Ground and Yellow for +12V DC. TM-250 Miniature CCD Camera... -

Rotate the connector while applying slight pressure until the keyways line up. Press the connector into place until firmly seated. Plug the power cord into the 100V AC socket. This will power the camera up. TM-250 Miniature CCD Camera... -
Page 13: Attaching The Video Output
75Ω termination. Standard RG-59 type coaxial cable should carry a full video signal for up to 500 feet. To output the video and input the power and sync to a camera over a single cable, use the PULNiX multi-conductor cables, such as the 12P-02S, etc. The mini coaxial leads in PULNiX multi-conductor cables are designed for short runs of no longer than 100 feet. -
Page 14: Operation
Note: Functions of the F1 and F2 switches vary depending on the operating mode selected. 3.1.2 Shutter Control Shutter speeds on the TM-250 can be controlled using DIP switches S3, S2, S1, and S0. The following tables show the various switch settings in different operating modes. - Page 15 TABLE 2. Switch Position Shutter Speed (Sec.)

Page 17: Field And Frame Modes
3.1.3 Field and Frame Modes The standard factory setting for the TM-250 camera is FRAME MODE. The field and frame integration mode is selectable using the switch on the rear panel of the camera. The frame integration is used to separate all CCD pixels. -
Page 18: External Sync
Page 12 Operation 3.2 External Sync The TM-250 can accept external sync from an external sync generator or frame grabber. Its input specifications are: Internal/External auto switch fH=15.734 KHz ±5%, fV=59.95 Hz ±5% Note: The TM-250 has a one (1) horizontal line delay between the input VD signal and the output video. -

Page 20: Standard Interlace Mode
3.3.2 Cyclic (Continuous) Shutter Mode With back-plate shutter control, the TM-250 operates at the internally predefined shutter speeds. Each field output is exposed for the same period. The shutter control varies the substrate discharge timing. The duration between the shutter pulse and transfer gate timing (11H from VD edge) decides the exposure time (16H for CCIR). -
Page 21: External Sync Mode
Please contact PULNiX for timing charts of various asynchronous shutter modes. 3.3.4 External Sync Mode TM-250 accepts standard RS-170 external sync, which is defined as horizontal sync (HD) and vertical sync (VD). The phase-locked loop jitter is designed to be the minimum (< 5ns) in this category using the latest PLL chip. -
Page 22: Tm-250 External Signals
Async Mode operation, Integration Mode operation, and Reset-Restart operation. 4.1 External VD The TM-250 I/F circuit intentionally delays the external VD for two pixel clock period. This ensures that the phase of external HD comes earlier than that of VD with any cable length and absorbs the effect of jitter caused by the user's sync generators. -

The discharge and transfer repeats in every field at a predefined timing. The discharge occurs in every line and stops at the defined timing in one field. The duration between the last discharge and transfer determines exposure time. TM-250 Miniature CCD Camera... -

2 lines or more in width. The leading edge of TRIG pulse produces DSUB (discharge) pulse and starts the exposure. The transfer (read-out) occurs at the 11th line after EXT VD pulse is fed. A full picture field can be obtained in every field. The TRIG must be wider than one line. TM-250 Miniature CCD Camera... -

VINIT pulse implied but before transfer occurs at 11th line for TM-250, and at 16th line for TM-260. When the F2 switch is Up (ON) in Frame storage mode, the camera obtains both odd and even field pictures. -
Page 29: Post-Reset Asynchronous Shutter Mode
The photo transfer occurs at the first line of the odd field right after the reset. Vertical shift starts after 11H for TM-250, and after 16H for TM-260. Only the image in the first odd field is valid. SYNC signal is continuous when F2 switch is Up (ON). -
