Power Over Ethernet (POE) voltage shielded crossover cable.
This Ethernet adapter cable allows devices that require non standard POE voltage pinout (4,5 V- and 7,8 V+) to operate on standard POE equipment with standard POE pinout (4,5 V+ and 7,8 V-).
Works with Motorola Canopy among others.
Allows non-standard devices to operate on standard POE switches and POE inserters.
