Up to 32 electronic signs can be connected directly to the MessageNet or Silent Messenger Servers. Signs are connected using Cat 5 UTP. (Standard Network cable). This cable can be use to connect signs located up to 700 feet from the server depending on environmental and electrical conditions.

Three wires in the Cat 5 are used to communicate to the electronic Signs. Cable is terminated at both ends with RJ11 style phone jacks (6 conductor). Signs communicate over this media using RS232 at up to 9600 baud depending on the model of sign.

Signs can be used as "Visual Pagers" and can be cummunicated to via the commercial paging networks such as Arch or Skytell. The MessageNet or Silent Messenger server can be directly connected to the paging providers paging terminal via a dedicated line or it can communicate using one or more dial modems.

Signs can be located anywhere the paging company provides coverage.

Multiple paging companies can be used at the same time if desired to get the needed coverage. For additional information about Visual Paging go to www.visualpaging.com for further description.

Electronic Signs can be connected to any users PC by using the Com 1 or Com 2 ports. From the Com port on the PC, Cat 5 cable can be run up to 700 feet to the electronic sign.

A small program is required to be placed on the users PC to provide communication to the sign over your network. The commuication program does not interfere with the general use of the PC by its users and works with Windows 95, 98, 2000, and NT operating systems.

Electronic Signs can be connected to the network via wireless modems. These modems operate at up to 9600 baud over distances ranging from 300 feet to 2500 feet where line of site is unobstructed. These modems are advanced frequency hopping spread spectrum 2.4 Ghz devices.

The modems provide a bidirectional data path so that sign status information can be return to the server if desired. One server attached Modem can service multiple sign attached modems. The number of down stream modems being serviced in this manor is dependent on the data rate required by each sign.
