October 8, 2003 Networking Alpha Signs (9700-0112C)
14 Wired networks
LAN—multiple signs
TCP/IP network
Use this configuration when connecting signs to a TCP/IP network using unique IP addresses. The number of
signs on this network is limited by the number of available IP addresses, but the potential length of the network is
unlimited:
TCP/IP and RS485 network
Use this configuration when connecting multiple signs to a TCP/IP network using only one IP address. One
MSS485 Micro Serial Server is used and up to 32 signs can be connected. Total length of the RS485 network is
limited to 4,000 feet at 9600 baud or 9000 feet at 2400 baud, unless a repeater box is used.
Only one IP address is needed, but each sign on the RS485 network can have its own serial address so it can be
sent messages different from other signs:
