Symbol PL4507 Electrical Information
Power Supply Requirements
The Symbol PL4507 decoder board can be powered from one of two possible supply voltages: Host 5 VDC or
3.3 VDC. The PL4507 uses an intelligent hardware multiplexer to configure the most efficient power supply
arrangement for the combined PL4507/SE4500 system.
shows a block diagram of the supply
multiplexer.

Symbol PL4507 Power Supply Multiplexer
The multiplexers are low resistance switches that automatically select between their A and B inputs. If both inputs
are present (e.g., Host 5 VDC and Host 3.3 VDC) the A input takes precedence.
This arrangement allows powering the PL4507 using 3.3 V, 5 V, or combined supply voltages that offer improved
efficiency for the overall system due to the different supplies that the PL4507 decoder and SE4500 imager engine
require internally.
