4.5  Console Port Wiring 
 
A RS232 console port for configuration and management of the device is located on the LED 
display module shown in Figure 13.  This port is intended to be a temporary connection during 
initial configuration or troubleshooting and allows for direct access to the serial-based management 
console.  The connection is made using the DB9-Female to RJ45 console cable included in the 
device packaging shown in Figure 14.  Console connection settings are:  57600 baud, no parity 
bits, 8 data bits, and 1 stop bit.
