M355 11-Digit Count Down/Up Display

The M355 Count Down/Up Display shows countdown or countup from a PSEUDO IRIG timecode input. Alternatively it reads and displays time-of-day from a modulated carrier time-code source (such as IRIG B) or by connection to an asynchronous serial time-code source via an RS232 or RS422 interface. Single-sided display Seven segment high-intensity LED digits Rack-mountable Automatic recognition of time code format Particularly suitable for range-timing display Choice of input options: Serial (via RS232 or RS422 interface); Timecode (IRIG CS525z); Modulated carrier timecode (IRIG-B, PSEUDO IRIG-B, NASA36, AFNOR S 87500, 2137, XR3) The display shows time in a number of formats including sign with days or hours through to tenths of a second. The equipment is designed for use in range timing display or other general-purpose time display applications particularly where event time management is required. Most time formats are automatically recognised; where time formats share a common time-code structure (such as IRIG B and Pseudo IRIG) an internal switch is used to confirm the display requirement. Model 170 Countdown / Up Generator is compatible with this display and can feed it directly with Pseudo IRIG Time-code for range timing applications. PSEUDO IRIG display Unlike the other time-codes accepted by the display, Pseudo IRIG B does not contain the time-of-day but a countdown / countup time. Both countdown and countup times are incrementing in the same direction but countdown time is displayed as a negative quantity which gets smaller as it approaches zero. If Pseudo IRIG timecode received, countdown / countup is displayed rather than time-of-day.
