Introduction - 2 • All models may be programmed to provide one of seven serial RS232 ascii data output messages when used in stand-alone or radio-synchronised modes - program function 9. The output messages may be either every second, after receipt of an ascii `T’ or `t’ - program function 7, selection 4) or on a voltage free switch closure - program function 7, selection 5. The output messages may be at 1200, 2400, 4800, or 9600 baud - program function 10 - , with seven or eight data bits - pro

Power Supply Connection 400A series clocks may be supplied for 230v ac, 110/120v ac, 12v dc, 24v dc or 48v dc. The clock must be connected to the appropriate supply after first verifying the correct voltage by reference to the supply voltage label fixed to or printed on the rear panel of the clock. A connection to the earth line must be made to ensure safe oper

EBU/SMPTE Code Formats 400A series clocks may be programmed to synchronise to EBU/SMPTE time code signals when the optional 404.E interface is fitted. Calendar clocks may be synchronised to one of two date formats. Format 1 (*) is desgined to work with other manufacturers' displays - eg Leitch (TM) whereas Format 2 (**) displays time/date on a video signal in an understandable order. Both formts work with V-401A/V-420A/V-490A Time Displays (ie no date) Application 401, 420 & 490 Clocks Calenda

Serial ASCII Data Formats 400A Series clocks and calendar clocks, when fitted with a 404.2 (RS232) or 404.4 (RS485) optional internal interface module, are capable of synchronisation to one of three serial ASCII data message formats and will transmit messages in seven formats. The clock may be programmed to receive or transmit messages at 1200, 2400, 4800 or 9600 baud - program function 10 -, seven or eight data bits - program function 11 - and odd or even parity - program function 12.

402A Stopwatch Controller - 1 The 402A Stopwatch Control unit enables a 401A,420A or 490A series clock to be used both as a multifunction stopwatch and a time-of-day clock with the display freely switchable between time-of-day and stopwatch time. The time-of-day count may be synchronised to a wide variety of external time codes, impulses and time signals. Four switches control the stopwatch count, display selection and function programming of the control unit. The operation of these switches is
