Rapco Time Code ProductsA range of Time code Generators and Readers in 1U half-rack or full rack width
package. Supports all popular timecodes.
343 / 344 TYPE UNITS Click here for
datasheet of Timecode Generator Units
Rapco types 343 and 344 Time Code Generators are compact half width units designed to complement type143 and 144 readers. The unit may be rack mounted either singly, or in pairs. The 343 and 344 can be combined with companion readers types 143 and 144 to
form a 1U high 19" rack mount unit. 393 / 394 / 395 TYPE UNITS Rapco types 393, 394, and 395 Time code Generators are designed to accept a range of optional interfaces and other functions which make units especially suited for integration into Time code and Frequency generation and distribution systems. Time keeping is controlled by an internal precision oscillator or, optionally by an external frequency standard. Power consumption of the unit is low ; ac power supplies are standard and a dc input can be fitted for use either as the primary power source or as a support to ac mains. Internal battery back-up is available to further support both ac and dc operation. The microprocessor-based design enables low cost customizing for special applications . All of these popular Timecode units are still available to order. For new systems requiring timecode generation consider also GPS sources [eg 1814] with integrated Timecode for a cost-effective solution.
143 / 144 TYPE UNITS

datasheet of Timecode Reader Units
Rapco types 143 and 144 Time Code Readers are designed to have a high performance in a compact 1/2 rack width enclosure. The units may be rack mounted either singly, or in pairs. These microprocessor based units can be configured to read a wide range of standard and custom time code inputs at low cost. The standard XR3 and IRIG codes are all fully supported and time may be read in either direction at widely different speeds. In addition to the standard RS232 Control port, models are available with IEEE-488 and high speed parallel interface. The 143 and 144 can be combined with companion generators types 343 and 344 to form a 1U high 19" rack mount unit.
For off tape applications, a simple coincidence search option is available. All of these popular Timecode units are still available to order.
Rapco types 193 and 194 Time code Readers are designed to accept a range of optional interfaces and other functions which make units especially suited for integration into Time code distribution systems. Power consumption of the unit is low ; ac power supplies are standard and a dc input can be fitted for use either as the primary power source or as a support to ac mains. The microprocessor-based design enables low cost customizing for special applications .
Rapco DA10 Series -- Timecode
Distribution Unit
This range of Timecode Distribution Amplifiers is available in many variants to suit different applications. Amplifiers can be independent or commoned and the high input impedance means that units can be daisy chained to produce large numbers of outputs. The transformer coupled versions have drive capability of up to 1 km when terminated with a Rapco Time Code Reader.
Rapco ACU5M -- Serial Data Changeover Unit
This unit provides a convenient way to introduce the security of a duplicated RS232 source into a system where such a facility is needed. The changeover process is fully automatic with a front panel indication of which source is currently in use.
Rapco SDU10/SDU22 -- Serial Data Distribution Units
The SDU10 is a 1U high x 19inch rack mount assembly that is intended for use in situations where a serial ASCII message packet, broadcast from a central source, must be connected to a number of remote equipments using separate signal cables. It is a unidirectional, one-input / ten-output buffer for handling RS232 level signals. There are no return-channel (data receive) facilities, and no 'handshake' lines are implemented; this is because the data packets from the source are timed transmissions, related to a defined on-time point (eg UTC). For this reason the equipment served must not hold up the data or the timing would be lost. In a typical application, the source of data would be a Rapco 1804 or 2804 GPS Timing unit, which was broadcasting 1-per-second message packets from an RS232 serial port, each packet being timed to start immediately after the UTC 'on-time' mark. The SDU10 allows the transmitted output signal from this port to be connected to ten remote units. It provides opto-isolation between its input connector and the ten output connectors and also between the output connector 0V pin and chassis earth, because each output signal buffer is powered from its own isolated dc/dc converter supply. Outputs are connected through 9-way 'D' connectors at the rear panel, although only two pins are wired on each connector (Output signal and signal 0V).
