Revision: 9.6.0.2

Precautions
Reduce the risk of injury or equipment damage by observing the following
precautions when installing Cognex products:
lRoute all cables and wires away from high current or high-voltage power
sources to reduce the risk of damage or malfunction due to over-voltage,
line noise, electrostatic discharge (ESD), power surges, or other
irregularities in the power supply.
lDo not install Cognex products where they are exposed to environmental
hazards such as excessive heat, dust, moisture, humidity, impact, vibration,
corrosive substances, flammable substances, or static electricity.
lChanges or modifications not expressly approved by the party responsible
for regulatory compliance could void the user’s authority to operate the
equipment.
lInclude service loops with all cable connections.
lEnsure that the cable bend radius begins at least six inches from the
connector. Cable shielding can be degraded or cables can be damaged or
wear out faster if a service loop or bend radius is tighter than 10X the cable
diameter.
lThis device is certified for office use only and if used at home, there can be
frequency interference problems.
lUse this device in accordance with the instructions in this documentation.
lAll specifications are for reference purposes only and can change without
notice.

DSMax Frame Grabber
The DSMAX Frame Grabber is a PCIe card that gathers, stores, and processes line-
profile scans from the DSMAX sensor at rates up to 18 kHz using the CoaXPress
protocol. Two coaxial cables attach a DSMax sensor to the frame grabber with BNC
connectors.
The DSMAX Frame Grabber has two general operating
states:

Installation
To install a DSMax frame grabber, perform the following steps:
1. Wear a grounded, static-dissipating wrist strap for ESD protection.
2. Turn off the PC and remove its cover.
3. Select a free PCIe x4 Gen2 expansion slot.
4. Remove the slot cover and store it for later use.
5. Remove the hex nut and washer (highlighted) from the base of each BNC
connector on the faceplate of the frame grabber:
6. Press the DSMAX frame grabber into its PCIe slot until it is firmly seated.
6

7. Re-install the hex nut and washer to the base of each BNC connector to
help secure the DSMax frame grabber to the chassis of the PC.
8. Connect a +12V DC power supply to the 6-pin Molex PCIe auxiliary power
connector.
9. Replace the cover of the PC.
10. Connect the coaxial cables to the Frame Grabber using the BNC
connectors.
I
DSMax does not support single-cable acquisition.
11. Turn on your PC.
12. Launch your VisionPro software and configure the DSMax sensor as an
image source.
Refer to your VisionPro documentation for details.

Indicator Lights
The CoaXPress status indicator lights directly behind the BNC connectors
(reference Page 4) follow specific color schemes detailed by CoaXPress standard
Version 1.1.
CoaXPress States CoaXPress Indicator Light

System booting Solid Orange
Connection detection in progress, PoCXP active Fast flash alternate green / orange shown
for a minimum of 1s even if the connection
detected is faster
Device / Host incompatible, PoCXP active Slow flash alternate red / green
PoCXP over-current (Host only) Solid red
Device / Host connected, but no data being transferred Solid green
Device / Host connected, waiting for event (e.g. trigger, exposure
pulse)

Error during data transfer (e.g. CRC error, single bit error detected) 500ms red pulse in case of multiple errors,
there shall be at least two green fast flash
pulses before the next error is indicated
System error (e.g. internal error) Fast flash red

Input/Output Signals
Refer to your installed VisionPro documentation for details on how to connect an
encoder and hardware triggers to the DSMax frame grabber.
The DSMax frame grabber supports the I/O signals as shown in the following figure.
The frame grabber supports a maximum input voltage of 24V.
Signal Description
Encoder PhA+ Floating input. Use this when you
need to use a single ended input.
Encoder PhA- Weak pull up to 2.5V.
Encoder PhB+ Floating input. Use this when you
need to use a single ended input.
Encoder PhB- Weak pull up to 2.5V.
Common GND Used as ground for both encoder and
trigger I/O input.
Trigger+ Weak pull up to 2.5V.
Trigger- Weak pull up to 5V
Differential voltage of 1V needed. For example an single ended encoder
input into PhA+ needs a maximum voltage of 1.5V to signal ‘0’ and a
minimum voltage of 3.5V to signal ‘1’.
