The ESE ES-991U is a Time Code display featuring 2.3" amber LED displays. The unit accepts, via the rear-mounted BNC connector, either ESE Time CodeT (TC76T, TC89T, or TC90T) or SMPTE/EBU Time Code. RS-232C ASCII Time Code (format "0", "1" or "A" at 9600 baud) may be input via the rear-mounted 9-pin connector. The ES-991U will automatically determine which code is being received. An internal DIP switch is used to configure the display for 12 or 24 Hour format, or to display the Date instead of time-of-day (if incoming time code contains Date information, such as ESE TC90, date-encoded SMPTE/EBU or ASCII formats "1" or "A"). If the Time Zone option is ordered, an internal DIP switch is installed for this function. If receiving ESE Time CodeT from a timer, the unit will display Minutes & Seconds.
