Key features ■ Display IRIGB, RS422 or NTP time code ■ Automatic selection of the available time source. ■ Redundant operation according to multiple time sources ■ Display chaining ■ 2U height (89.08 mm) or 144 mm ■ Brightness control SR1246 and SR1256 are robust and light time displays, that can be used in a rack or wall mounted. They come in two models: ■ SR1246, 2U height, width 19', 80 mm depth, rack mount or wall mount. 7 red LED segments, visibility > 15m. ■ SR1256, 144 mm height, 660 mm width, 80 mm depth, wall mount. 7 red LED segments, visibility > 30 m. This multi protocol display is able to receives, processes and displays a TU time code, received in the following 3 formats : • NTP Digital ETHERNET • Digital RS422 (ASCII time chain) • IRIG-B12X, AFNOR, and IEEE1344 The display uses 6x7 LED segments for time with the format : HH :MM :SS LED and 4x16 segments LEDs for : • The day of the year or the type : « UT », « CD » or « H0 » • One default mark : "*" • The sign + or - for the CD To operate the display must be connected to the 230V AC sector source and get at least one of the following time source : • NTP frame : network link, network cable CAT5 with RJ45 standard connector. • RS485 frame: digital link carrying the time frame, twisted pair cable with Sub'D 9 pins male connector. • IRIGB signal : analog modulated signal, coax cable with BNC connector. The display automatically selects the time source available. Settings Display setting is done using one serial RS232 link with the following characteristics : 115200 bauds, 8 bits, no parity, 1 bit stop. The link "Console" allows the direct connection with a PC. A software like Windows HyperTerminal or Linux/ Minicom is well suited for terminal setting.

The automatic operation of the display depends of the programmed configuration. This configuration is stored in a non volatile memory of EEPROM type. It is restored when the display is powered On. Brightness is adjustable with 10% steps. The setting is done using two push buttons « + » and « -» located on the rear face. The setting is automatically memorized. The RS422 output allows to chain the displays. The RS422 output is always generated whatever the type of the received frame. The display is acting as IP converter to RS422 or IRIGB converter to RS422. NTP Two operating modes are...
