The AE122-354 is 12-inch 2-digit super-bright display, RS232/RS485 serial input. Option 354 provides an intelligent serial input for the AE series displays. This is not standard RS232 input. However, up to 50 AE series devices with this option can be connected to a standard RS232 port, at distances up to 2,000 feet away. Signal drivers are available to provide systems with unlimited numbers of displays. This option allows AE Series displays to communicate with host computers, master clocks, process computers (PLC's), multi-media system controllers, and AE21 display controllers. Applications include computer controlled master clock systems, production monitors, time to next show timers, process indicators, and message displays.

A simple 10 Byte message is required to send data or control information to the display. It provides addressing, mode selection, six characters of data, and display attributes. Free software is available for Computer and Master Clock based systems.
