1 Hardware Introduction
1.1 Product Description
The JAI RM-4200CL series consists of high-resolution, high-speed monochrome and color progressive scan CCD
cameras with dual-tap output (Camera Link software allows 12-bit, 10-bit, or 8-bit output).1 The interline-type
CCD permits full vertical and horizontal resolution of very high speed shutter images and applications. The
electronic shutter, which has speeds to 1/16,000 sec., can be reset asynchronously by external pulse control.
The dual-tap frame rate is 15 fps. A single-tap mode is user-selectable at 8 fps. A square imager format with
uniform square pixels provides superior image definition in any orientation. On-chip micro lenses provide
increased sensitivity.
The RM-4200CL has a full dynamic range control function, which can be set to convert 12-bit input to either 10bit or 8-bit output through the knee slopes of the externally selectable look-up table
the CCD’s full dynamic range in the normal output signal range. It can also be configured to produce 12-bit
linear output – there is no LUT support in this mode. As a dual-tap output camera, the RM-4200CL has dualchannel auto black level balancing and auto gain balancing functions. All the key functions are controlled by
means of the Camera Link serial communication interface either via a GUI or serial commands.
Synchronized data and clock phases are necessary for multi-camera operations, and a standard feature of all
RM-4200CL cameras. The RM-4200CL has a phase lock loop (PLL) to synchronize on the external horizontal drive
(Hd) for multi-camera operation that is offered as a standard feature.
Applications for the RM-4200CL include machine vision, medical imaging, intelligent transportation systems,
high-definition graphics, on-line inspection, gauging, character reading, archiving, and high-security
surveillance.

1.2 Features
• Miniature size and light weight
The printed circuit boards in the RM-4200CL have been arranged based on a new design philosophy. This
creates modular electronics for the camera, giving it flexibility. In addition, the use of miniature solid-state
components results in a compact, lightweight camera that is 51mm x 51mm x 74mm in dimensions, and weighs
only 191 grams.
• Imager
The RM-4200CL uses a dual-tap progressive-scan interline transfer CCD that has the following features:
− Resolution of 2048 x 2048 active pixels for excellent image quality
− 7.4 x 7.4 μm square pixels for precise dimensional measurement
− High-speed electronic shutter capability, that eliminates the need for a mechanical shutter through
high dynamic resolution of moving objects
− Progressive-scan CCD eliminates interlace deterioration of image and increases ease of computer
interface
− High sensitivity and low noise with fast scanning rates. The CCD has an excellent S/N ratio that is
greater than 58dB.
− The CCD has built-in microlens technology for increased quantum efficiency

The RM-4200CL series consists of the TM-4200CL, RM-4200CL (monochrome) and the TMC-4200CL and RMC-4200CL (color). Unless
otherwise noted, all information contained in this manual is relevant to all models.
Hardware Introduction 1
RM/TM-4200CL Series
• Electronic shutter
The RM-4200CL has a substrate drain-type shutter mechanism which provides superb pictures at various speeds
without smearing. For more information, see Section 6.4, “Electronic Shutter,” on page 39.
• Asynchronous reset
The RM-4200CL captures async reset images and provides single-shot video output with single FDV (frame data
valid). This makes it simpler for an ordinary frame grabber to capture the async reset images. The RM-4200CL’s
asynchronous reset is flexible and accepts external horizontal drive (HD) for phase locking. When the VINIT (5V)
pulse is applied to CC1, it resets the camera's scanning and purging of the CCD.
The RM-4200CL has two modes to control the asynchronous reset and shutter speed:
− External VINIT with pulse width - the duration between pulse edges controls the shutter speed
externally.
− Internal shutter speed control - the speed control varies from 1/125 to 1/16,000 sec. The video
signal and FDV starts with internal V reset timing originally set to respond to shutter speed,
although this can be changed to sensor or other input.
• Output
The RM-4200CL has dual-tap/single-tap 12-bit, 10-bit or 8-bit Camera Link output. The analog output is 714 mV
p-p composite video (75 ohms) on all models.
• Dual-Channel Auto Black Level Balancing and Gain Balancing
The RM-4200CL, as a dual-tap output camera, has dual-channel auto black level balancing and auto gain
balancing functions.
• Warranty
Please contact the JAI factory representative for details about the warranty.

2.2 Camera Setup
2.2.1 Heat Dissipation
The RM-4200CL is a compact 2K by 2K camera. Since all the electronics have been packed in a compact
package, the outer case of the camera can become hot due to heat dissipation. For optimal performance, JAI
recommends using a cooling fan to set up a positive air flow around the camera and following the precautions
below.
• Mount the camera on a large heat sink (camera bracket) made out of heat-conductive material like
aluminum.
• Make sure the flow of heat from the camera case to the bracket is not blocked by a non-conductive
material like plastic.
• Make sure the camera has enough open space around it to facilitate the free flow of air.
2.2.2 Connector Pin Configurations
2.2.2.1 12-Pin Connector
The RM-4200CL has a 12-pin Hirose connector for power input and signal integration. Pin #1 is Ground and pin

2.2.4 Power Supplies and Power Cable Setup
2.2.4.1 Power Supplies
The RM-4200CL camera requires 12V DC power that is obtained through the 12-pin connector located on the
rear panel of the camera. JAI power supplies feature a 122-240VAC / 12VDC 1.2A universal voltage power
supply. JAI recommends the following power supplies:
PD-12UU PD12UU (No 12-pin Hirose)
PD-12UUP PD-12UU with 12-pin connector
PD-12UE PD-12UU (No 12-pin Hirose)
PD-12UEP PD-12UU with 12-pin connector
For users providing power through the 12-pin connector, the PD-12P, PD-12UEP and PD-12UUP power supplies
are available with the 12-pin mating connector already attached to the leads from the power supply. The PD12UU and PD-12UE power supplies can be connected to the JAI power cable by means of a terminal strip or
directly.
When wiring the PD-12UU and PD-12UE power supplies directly, please note the following:
• The lead ends must be twisted together and tin-soldered for strength and electrical continuity.
• Use shrink tubing or a similar insulator to prevent exposed leads from touching and shorting.
• The +12V lead is marked with a red stripe or white lettering; be sure not to reverse the leads.
• All connections must be properly insulated to prevent shorting.

Note: Make sure that the unused leads are not touching and that there is no possibility that exposed wires
could cause the leads to short.
2.2.4.3 Building Your Own Power Cable
Refer to the 12-pin connector pin-out in Table 1 on page 13. Connect the Ground lead to pin #1, and the +12V
DC lead to pin #2 of the 12-pin connector. Power must be DC-regulated, and of sufficient current to properly
power the camera.
2.2.4.4 Attaching the Power Cable to the Connector
The 12-pin connector is keyed and will only fit in one orientation. Follow these directions to properly attach
the power cable to the camera connector:
1. Rotate the connector while applying slight pressure until the keyways line up.
2. Press the connector into place until firmly seated.
3. Plug the power cord into the 100V AC socket. This will power up the camera.
Note: If using a power supply other than the standard PD-12U Series from JAI, certain characteristics are
required of the power supply and the wiring in order to properly power the camera. The camera requires
12V immediately upon start-up; no slow ramps. Once power is applied, the power supply must be able to
support a 2A to 2.5A in-rush current for approximately 200µs to prevent the voltage at the camera from
dropping below the 10.8V minimum required. Dropping below this will result in the camera’s internal
power supply lowering its impedance in an attempt to draw more current. Since no more current will be
available, the voltage at the camera will drop instead. This will result in a steady-state hang-up which
will damage the camera’s power supply and cause the camera to cease operating or to operate in an
unstable manner.
2.2.5 Attaching the Analog Video Output
When connecting the RM-4200CL to an analog frame grabber or a monitor, use the BNC connector on the back
panel of the camera. The input of the monitor should be balanced for 75 ohms termination. Standard RG-59
type coaxial cable should carry a full video signal for up to 500 feet. The RM-4200CL has a two-row binning
mode that can be used to display real-time images on the PVM-942 or PVM-1242 monitors. These monitors are

specially modified to accept a 30Hz progressive scan image. The multi-conductor cable 12P-02S can transmit
analog video, power, sync. signals, and serial communication. The mini coaxial leads in JAI multi-conductor
cables are designed for short runs of no longer than 50 feet.
Note: Make sure that no extraneous wires are visible which could cause a short.
2.2.6 Attaching the Camera Lens
The RM-4200CL camera accepts 1.2-inch or larger format size C-mount lenses. To attach the C-mount lens2 to
the camera, carefully engage the threads and rotate the lens clockwise until it firmly seats on the mounting
ring. Do not force the lens if it does not seat properly. Please note that some lenses with extremely long
flangebacks may exceed the mounting depth of the camera.
2.2.7 Adjustable Back-Focus
Before cameras are shipped, back focus is carefully set using a collimator, oscilloscope and other specialized
equipment. While the factory-set focus serves well in most cases, an adjustable back focus makes it possible to
improve image sharpness when using lower-cost zoom lenses, custom optics, or in unusual parameters.
There should be an obvious need to refocus the lens before attempting to change the back focus. This is a very
exacting task. Some cameras have been returned to the factory to reset the back focus after failed attempts to
change the focus by customers. It might be wise to label cameras whose back focus was adjusted.
1. The camera must be connected to a monitor before attempting to adjust the back focus.
2. To back focus the camera, first attach a C-mount lens in the mount. Be certain that the lens is properly
seated.
3. Next set the lens focus to infinity (if the lens is a manual iris, set the iris to a high f number while still
retaining a well illuminated image).
4. Loosen the three miniature hex set-screws (use a 0.9 mm hex wrench) that lock the focus ring in place
(two screws for a CS-mount). Slowly turn the lens and focus ring assembly back and forth until you obtain
the best image of the desired object. This sets the back focus. Once the best image is obtained, tighten
the focus ring set-screws until they are snug. Do not over-tighten the screws.
Note: Mini-bayonet cameras adapted to C-mount do not have the back focus feature.

C-mount to F-mount and C-mount to K-mount adapters are available for larger format lenses (35mm). Check with local
photography dealers for these lens adapters.
