PRODUCT INFORMATION B&B ELECTRONICS

Models: PES1A, PESV1A

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).
