Switch dart M, GigE, 2 Port, PoE+#

The Switch dart M, GigE, 2 Port, PoE+ for Basler dart M GigE cameras provides an Ethernet connector and access to the camera's GPIO lines.

信息

If you use a Basler dart M GigE camera module with a Basler dart M GigE switch, the dart M GigE switch is used instead of the Interface Board dart M GigE RJ45 PoE.
If a dart M GigE switch is used, the I/O circuit is located on the switch; see the Circuit Diagram (dart M GigE Switches) topic.

主要功能#

  • Can be used with all Basler dart M GigE cameras
  • Power over Ethernet (PoE and PoE+)
  • 5 V power supply for connecting additional electronic components via the I/O Connector
  • Up to 1 Gbit/s bandwidth
  • Up to two dart M GigE camera modules on one switch can be accessed with just one data cable
  • GPIOs of cameras accessible via I/O connector on switch
  • Supports jumbo frames

巨型帧

  • If you increase the packet size above 1 500 Bytes in the camera, you must enable the Jumbo Frames support on all network devices. Otherwise, streaming may fail due to blocked packets.
  • If you want to use the maximum packet size for jumbo frames, set the network adapter to its maximum value as described in the Network Configuration (GigE Cameras) topic. Also set the GevSCPSPacketSize parameter to its maximum size. Bear in mind that all Basler dart M GigE cameras only support a packet size of up to 8192 Bytes.

Basler dart M GigE switches are delivered without a housing.

警告 — 烫伤危险

During operation, the components of the GigE switch generate higher temperatures. Touching the switch and its components while the switch is turned on may cause burns.

Take measures to ensure that the hot components of the switch cannot be touched during operation (e.g., mounting the switch into a housing).

Notice – Temperatures outside the specified range may damage the switch.

Operating the switch at temperatures outside of the range given in the specification table causes the following problems:

  • The switch itself may get damaged.
  • The lifetime of the switch components decreases.

Ensure the temperature of the switch component stays below 70 °C (158 °F)!
Ensure the temperature of the LAN transformer module stays below 85°C (185 °F) when using PoE!
Provide sufficient heat dissipation.

NOTICE – Voltages outside of the specified range may damage the switch.

You must supply power within the safe operating voltage range given in the General Specifications table.

电气要求#

Power Supply#

Power supply via Power over Ethernet (PoE and PoE+): Power must comply with the IEEE 802.3at (PoE+) or IEEE 802.3af (PoE) specification.

信息

The Switch dart M, GigE, 2 Port, PoE+ is designed as a PoE+ PD (PoE powered device). The maximum power consumption of all components together, i.e., the switch, all connected cameras and other attached equipment, must be less than 25.5 W in total (when PoE+ is used) or less than 12.95 W in total (when PoE is used). This power must not be exceeded.
The power consumption of the switch depends on traffic and temperature. Due to the maximum current rating of the camera port connector, the maximum power consumption of each port must be less than 6 W.
See the Power Consumption for Different Use Cases table for more details.

Power Consumption for Different Use Cases#

The following table shows typical power consumption values for different use cases.

用例 Power Consumption (W)
Switch without dart M camera module; connected to LAN 1.1
Switch with 2 dart M camera modules; no image captured 6.0
Switch with 2 dart M camera modules; images captured; max. bandwidth 8.0
Switch with 2 dart M camera modules; images captured; max. bandwidth;
external load 7.5 W via the 5 V power supply output		 16.4

信息

If the power consumption of the dart M GigE switch in your use case approaches ~12 W or higher, Basler recommends using PoE+ with more power.

通用 I/O 线路#

NOTICE: Applying incorrect electrical signals to the GPIO lines can severely damage the board.

  • 最大负载电流：50 mA
  • 最小负载电流： 未指明。考虑以下条件：
    • 当负载电流低时，漏电流会产生更强的影响。
    • 输出的传输延迟随着负载电流的减小而增加。
    • 高阻抗电路往往更容易受到 EMI 影响。
    • 对于长线缆而言，电流越高，其压降就会越高。

有关 I/O 线路的更多信息，请参见 I/O 控制部分。

线缆要求#

以太网线缆#

  • 使用高质量的以太网线缆。建议使用带 S/STP 屏蔽的 Cat 5e 屏蔽线缆或更好的线缆。
  • 使用直通（跳线）或交叉以太网线缆。
  • 应避免靠近强磁场。
  • Basler 建议使用 Basler 线缆产品组合中的以太网线缆。
NOTICE – Mechanical stress on the Ethernet connector may damage the switch.

If mechanical stress is applied to the Ethernet connector (RJ-45 jack), provide strain relief for the cable to prevent mechanical damage to the dart M GigE switch.

I/O 线缆#

  • The I/O cable must have a cross-section of at least 0.09 mm² (close to AWG28).
  • The I/O cable is used to supply power.
  • A maximum cable length of 10 m must not be exceeded.
  • Recommended connector: TE 1-338095-0 (crimp type) or WR-MM 690157001072 (ribbon type)
  • 应避免靠近强磁场。
  • Basler recommends using dart M I/O cables.

信息

Be aware that pin 1 to 4 of the I/O connector can only be used as 5 V power supply for external components. Do not use them as external power supply, as it is used for the AUX power variants of the switch.

5 V Power Supply for External Electronics#

The I/O connector of the dart M GigE PoE+ switch provides 5 V power supply that you can use for connecting external electronic components to your system, e.g., a pattern projector for stereo use cases. The 5 V OUT is secured via a 1.5 A fuse and a suppressor diode; see the following circuit diagram.

Circuit Diagram I/O Connector, with Fuse and Suppressor Diode

NOTICE – A too high load may damage the switch.

Take the following into account when designing your system:

  • Ensure that the load on the external 5 V output does not exceed 7.5 W. Exceeding this limit will cause the fuse on the switch to trip, rendering the switch inoperable.
  • Also make sure that the sum of all loads/consumers on the switch (max. 2 cameras + external load on the 5 V output) plus the switch itself does not exceed the maximum power that the Ethernet card (NIC) installed in the computer can provide via PoE.

For further information, see the Power Consumption table.
