P52
Chapter 1: Introduction
1-2
A 100M BaseT Ethernet controller (Wiznet) can be installed to provide network connectivity. A software
stack library is available, supporting network protocols like ARP, DHCP, UDP, ICMP, and of course TCP
over the Ethernet network.
Two channels of RS-232 drivers and a 5V linear regulator are on-board. An optional RS232 or RS485
driver can be installed for the optional 3
rd
UART of the host controller. The
P52
requires 8.5V to 12V DC
power supply with linear regulator, or up to 30V DC power input with an optional switching regulator
without generating excessive heat.
