Serial Server with Power over Ethernet
(PoE)
Description
Power-over-Ethernet technology is a new Ethernet extension intended to eliminate the
cost and clutter of power supplies. Using PoE, power is injected by the Ethernet switch
or Ethernet midspan device onto the Ethernet cable itself. With PoE, specially designed
Ethernet devices can draw their power through the Ethernet cable eliminating the need for separate wall-transformers
and power cords. Both PES1A and PESV1A offers RS-232 serial server with PoE. Additionally PESV1A adds 3
selectable power outputs for your end device.
Selectable power: While these units comply fully with the IEEE 802.3af standard governing PoE transmissions, there is
no standard for the power to serial devices such as bar code scanners, slip printers or other devices. This creates a
challenge for the system integrator, VAR, OEM and customer. To counter this, variable voltage levels are built into the
serial servers, selectable by switch or the built-in web server (PESV1A only). They can meet virtually any DC voltage
requirement, with power up to 4 W (125mA max in rush).
