Power-Over-Ethernet Module

A DIVISION OF TRIMBLE

64 Using the Optional Modules

– For HTTP client mode, define HTTP web server. ex: "www.posttestserver.com"

– For other modes, define as blank. ex: “”

POE_REMOTE_HOST_IP_ADDRESS

– Applicable only for UDP client or TCP client. Define host system IP address where

UDP/TCP server application is running.

– POE_REMOTE_HOST_NAME: Should be blank when the IP address is defined.

POE_REMOTE_HOST_PORT_NUMBER

– For HTTP client mode, define as “80”

– For other modes, define host system port number where UDP/TCP server

application is running.

– The best practice is to use port number within the range assigned for "Dynamic,

private or ephemeral ports".

known_ports#Dynamic.2C_private_or_ephemeral_ports

POE_REMOTE_HOST_HTTP_SERVER_DIR

– Applicable only for HTTP client mode. Define the directory name which will be

created in the HTTP web server. ex: http://posttestserver.com/data/2014/

07/21/xyz

Define the HTTP data format type

– POE_HTTP_CONTENT_TYPE_FORM_URLENCODED

– Currently only the url-encoded type is supported.

Initialization Process

PoE module initialization will be done only if other high priority interfaces (USB, Bluetooth)

are not successful.

PoE module initialization starts when POE_init() is called from init_output() as part

of task_Wedge task initialization.

POE_init() will initialize the Wiznet chip and also initializes all configurable parameter

variables with configuration defines/values.

configures SPI interface

validates EEPROM contents

retrieves PoE module MAC address from EEPROM
