Setting Baud rate and Data format on an Ethernet-equipped sign
On signs that are Ethernet equipped, the Baud rate and Data format of the sign’s internal Ethernet card
must be identical to the Baud rate and Data format of:
• the sign’s internal DIP switches. See “Sign configuration” on page 6.
• the computer that is running the messaging software used to send messages to the sign.
To change the Baud rate and Data format of the sign’s internal Ethernet card, follow these steps:
1. Using the Configuration Utility software supplied with the sign, select Telnet to Device. The current
Baud rate, Data format (called I/F Mode), and other communication parameters will be displayed:
2. Select 1 for Channel 1 Configuration. Then set the various parameters as you are prompted:
Parameters of the sign’s internal Ethernet card:
• Baudrate 9600 – Factory setting. Can be changed.
• I/F Mode (see table below) – This is a hexadecimal
number (4C in this example) that sets the network
type (RS232, internal to the sign), number of data bits
(7/8), parity (None/Odd/Even), and number of stop
bits (1/2).
