Note: Version 1.3 (Jan 2011) will no longer have any codec/audio features
NPort® 5600-8-DT device servers can conveniently and transparently connect 8 serial devices to an Ethernet, allowing you to network your existing serial devices with only basic configuration. You can both centralize management of your serial devices and distribute management hosts over the network. Since the NPort® 5600-8-DT device servers have a smaller form factor compared to our 19" models, they are a great choice for applications that need additional serial ports, but for which mounting rails are not available.
Convenient Design for RS-485 Applications
The
NPort® 5650-8-DT device servers support selectable 1K-ohm and 150K-ohm
pull high/low resistors and a 120-ohm terminator. In some critical
environments, termination resistors may be needed to prevent the
reflection of serial signals. When using termination resistors, it is
also important to set the pull high/low resistors correctly so that the
electrical signal is not corrupted. Since no set of resistor values is
universally compatible with all environments, NPort® 5600-8-DT device
servers use DIP switches to allow users to adjust termination and pull
high/low resistor values manually for each serial port.
Convenient Power Inputs
The
NPort® 5650-8-DT device servers support both a power terminal block and
power jack for ease of use and greater flexibility. Users can connect
the terminal block directly to a DC power source, or use the power jack
to connect to an AC circuit through an adaptor.
LED Indicators to Ease Your Maintenance Tasks
The
System LED, Serial Tx/Rx LEDs, and Ethernet LEDs (located on the RJ45
connector) provide a great tool for basic maintenance tasks and help
engineers analyze problems in the field. The NPort® 5600’s LEDs not
only indicate current system and network status, but also help field
engineers monitor the status of attached serial devices.
Two Ethernet Ports for Convenient Cascade-style Wiring
The
NPort® 5600-8-DT device servers come with two Ethernet ports that can
be used as Ethernet switch ports. Connect one port to the network or
server, and the other port to another Ethernet device. The dual
Ethernet ports eliminate the need to connect each device to a separate
Ethernet switch, reducing wiring costs.
Automatic Warning Function by Speaker and/or E-mail
The
built-in speakers can be used to alert administrators of problems with
the Ethernet links or power input. The web console indicates which
Ethernet link or power input has failed. An e-mail warning can also be
issued when an exception is detected. These functions are valuable
tools that enable maintenance engineers to react promptly to emergency
situations.
