Things Embedded are an official Diamond Systems UK distributor and can supply the EPS-12000-CM fully configured.
EPS-12000-CM is a managed Layer 2 or Layer 3 Ethernet switch module offering twelve 10/100/1000Mbps copper twisted pair ports in the ultra-compact COM Express Mini form factor. It is ideal for rugged applications including industrial, on-vehicle and military, where space is at a premium. The switch is based on Diamond’s EPSM-10GX compact Ethernet switch module and uses a same-size carrier board to provide the power and magnetics circuitry to create a complete switch solution. This two-board design results in an ultra-compact size particularly suitable for UAVs and other unmanned vehicles.
All switch functions are managed by an embedded processor integrated into the switch. The processor is accessed via an in-band web interface over one of the Ethernet ports or via an out-of-band command-line interface over an RS-232 serial port. The integrated web interface provides an intuitive GUI for use in configuring and managing all switch functionality. On-board memory holds dual application images, boot code, MAC addresses, and other parameters, and can also be used for program execution.
EPS-12000-CM includes two innovative features that enable automatic power savings. The switch can detect unused Ethernet ports on network devices and power them down or place them in stand-by mode. Additionally, the switch actively adjusts the power level needed based on cable length, saving energy on links shorter than the 100m maximum specified length.
Input power is provided through the built-in, wide-range 6-34VDC power supply, enabling reliable operation with industrial power sources as well as vehicle power systems.
EPS-12000-CM was designed for use in vehicle and harsh environment applications. All I/O connectors are latching, providing enhanced reliability over the RJ-45 connectors used in commercial Ethernet switches. The -40ºC to +85ºC operating range makes it suitable for use in outdoor and vehicle applications.
EPS-12000-CM comes loaded with all required firmware, enabling its immediate operation without any development effort.
EPS-12000-CM comes with an integrated heat sink for cooling. An optional heat spreader is available for direct mounting to enclosure walls.
