2 Power Supply The unit can be powered by either connecting to a PoE port, or using an external power supply via the multifunction socket. The following information pertains to connecting power via the multifunction socket. IMPORTANT: Connect the multifunction socket only when the power supply is switched off. For description and pin assignment, see page 3. Range: V 30 V (rated value 2 V) DC; Max 00 ma The operating voltage is protected against reverse polarity. The cable shield is connected with the connector housing and should be connected to the protective conductor PE of the power supply. The shielded multifunction cable CCB is recommended. The operating voltage for the DS900 Series measuring device should come from a 2 V power supply that is only used for measuring equipment and not simultaneously for drives, contactors or similar pulse interference sources. Use a power supply with galvanic isolation. This page is left intentionally blank. 32 DS900 Series Sensors Quick Reference Guide DS900 Series Sensors Quick Reference Guide 33

3 Installation Instructions Only Cognex-approved shielded cables should be used. See page for cable part numbers. Cable shields should be connected to the machinery s potential equalization terminals in order to avoid electrical current ground loops. Cables should be routed in accordance with standard electrical wiring procedures in order to minimize electrical noise. The minimum bend radius of the cables is 0mm. Cognex recommends the use of a separate power supply, either ACC-2I (DIN rail mountable, input 230VAC, output 2VDC/2A); or ACC-QUINT-PS (DIN rail mountable, input 230VAC, output 2VDC/A). Mount the sensor according to the mounting instructions, see page Install the Ethernet interface hardware, if not already installed. 3. Install VisionPro software according to the instructions of the VisionPro documentation.. Make sure that your license is installed and valid.. Connect the DS900 Series Sensor to the PC via Ethernet.. Switch on the power supply (only applicable if not using PoE for power).. Open the Cognex GigE Vision Configurator PC application.. Check that the device is recognized by the PC. This may take a few seconds. The state LED indicates different error conditions by flashing. For the error codes, see page. If several errors occur at the same time, it indicates two of them alternately. Therefore the LED can continue to flash for some time after the rectification of an error. If no flashing occurs for several seconds, no error has occurred. NOTE: A DS900 Series sensor achieves highest precision measurements after it has been turned on for at least 20 minutes. 3 DS900 Series Sensors Quick Reference Guide DS900 Series Sensors Quick Reference Guide 3

4 Ethernet Connector The ethernet connection uses an M2- female connector. Pin No. RJ Connector Color stranded hook-up wire SC200/2900-x -pin screw connector (sensor side) Pin no. 0BaseT, 00BaseTX white (orange) Tx+ D+ 2 orange Tx- D- 3 white (green) Rx+ D2+ blue D3+ white (blue) 2 D3- green Rx- D2- white (brown) 3 D+ brown D- 00BaseT We recommend the Gigabit-Ethernet connection cable CCB for the Ethernet connection ( m). Characteristics: x 2 x 0. mm²; shielded. The sensors are to be preferably connected directly to the network connection or to a high-quality switch. As a hub would result in a massive data collision it cannot be used. The PC should have one or more network cards dedicated only for the sensors. Operating the sensor via Ethernet does not require any driver installation. However, the network settings have to be correct: If more than one network card is used, they must be placed on different subnets. Certain network settings will affect (and in some cases inhibit) the performance of the sensor (for example firewall and packet filter settings). A packet (payload) size of 02 bytes/packet is recommended. The sensor is capable of supporting jumbo frames up to 09 bytes/ packet, provided all network components also support jumbo frames. View on pin side male cable connector 2 3 View on solder pin side screw connector The sensor supports DHCP (this setting is activated by default). If the sensor is unable to obtain a network address via DHCP, the sensor will use link-local addressing (9.2.x.x). Note that IP address conflict detection is not implemented. The sensor supports Power over Ethernet (PoE). The sensor can be configured with a fixed (static) IP address using the Cognex GigE Vision Configurator PC application. 3 DS900 Series Sensors Quick Reference Guide DS900 Series Sensors Quick Reference Guide 3

The signal levels are switchable for all switching inputs between LLL (low-voltage-, TTL logic) and HLL (high-voltage-, HTL logic): LLL level: Low 0 V 0. V, high 2.

All switching inputs are identical. The used circuits have an internal electrical isolation. The inputs are galvanically isolated from the GND and Laser on/off. Each switching input has its own ground connection (Gnd-In to 3), which has to be connected with the external ground (synchronization/ trigger source or another device). 0 DS900 Series Sensors Quick Reference Guide DS900 Series Sensors Quick Reference Guide

Connect the cable shield with the potential equalization PE or the connector housing. ) The encoder input counts each edge. Quadrature encoders typically output edges per encoder step. NOTE: If the sensor is connected to a network adapter/switch that is capable of POE and if you also use the power supply of the multifunction port, these two power supplies have to be galvanically isolated. 2 DS900 Series Sensors Quick Reference Guide DS900 Series Sensors Quick Reference Guide 3

8 RS22, Synchronization NOTE: The DS900 Series Sensors support Power over Ethernet. If the sensor is connected to a network adapter/switch that is capable of POE and if you also use the power supply of the multifunction port, these two power supplies have to be galvanically isolated. For the multifunction socket, see page 3. For pin assignment, see page 3. The DS900 Series sensor has an RS22 port according to EIA standards, which can be parameterized as input or output via software. The RS22 port can be used to synchronize line-triggering of multiple sensors with each other. The internal terminating resistor (termination R T = 20 Ohm, see diagram on page ) can be activated or switched off via software. The signals must be operated symmetrically according to the RS22 standard. The RS22 port is galvanically isolated from GND and Laser on/off, but not from GND-In When used, one of the GND-In... 3 should be connected to the GND of the remote station in order to avoid potential differences. The multifunction socket can be used with either of the following configurations: Configuration Direction Standard setting for terminating resistor R T 0 Half-duplex, serial 200 Baud input/output On Half-duplex, serial 00 Baud 2 Half-duplex, serial 300 Baud 3 Half-duplex, serial 9200 Baud Half-duplex, serial 900 Baud input/output input/output input/output input/output Line trigger input input On Line trigger output output Off CMM trigger output output Off DS900 Series Sensors Quick Reference Guide DS900 Series Sensors Quick Reference Guide
