Change the Serial Address A serial address for an InView sign is a number from 1 to 254 in
hexadecimal (01 to FE). All signs leave the factory with a default
address of 1 or 01.
This serial address is resident in the InView display and is used for
RS485 networking. If one of the factory network communications
modules are used (2706-Pxxxx), this serial address is typically left at
its factory default and the network node or IP address is set in the
factory network communication module.

power to it. The following information should be displayed on the

• Firmware part number and version letter (xxxx).
• Amount of RAM in the sign, (256K).
• Serial address of the sign (a number from 01 to FE or from 1 to
254).
