Networking
AlphaPremiere™ series signs can be connected together so that messages can be sent to each of the signs
on the network. There are three ways to network AlphaPremiere™ series signs:
• RS232 (only available with the Standard Configuration) — This type of sign network allows “point-to-
point” communication. This means that a single PC can be connected to a single sign. The length of
this network is limited to 50 feet.
• RS485 (available with both Standard and optional Ethernet Configurations) — This type of sign
network permits communication to a single or to multiple signs. The length of this network can be
4000 feet @ 9600 baud.
• Ethernet (only available with the optional Ethernet Configuration) — This sign network allows
connection of almost an unlimited number of signs over a virtually unlimited network length.
RS232
The diagram below shows how to connect a sign to your PC, through the PC’s RS232 jack. The PC can not
be separated from the sign by more than 50 feet, due to signal loss in the cable:
