®& MODEL {78 RT SET y (REPERFORATOR TRANSMITTER-DISTRIBUTOR) FOR HIGH SPEED AUTOMATIC 4 MESSAGE RELAYING “A COMPLETE PUNCHED TAPE MESSAGE RELAY SET THAT... RECEIVES PUNCHES PRINTS STORES READS TRANSMITS ""*"* M28 PIVOTED-HEAD, MULTI-CONTACT TAPE R Fa offers automatic message relaying at its best—higher speed dependable operation, lower maintenance and your choice of tape punching and reading components that are ‘custom tailored"’ to meet a variety of applica- tion needs. Thus, whether for cross-office or cross- country relaying of data, the versatile Model 28 RT Set will provide the speed, dependability and adaptability so necessary to effectively handle your growing com- munications traffic. This component will receive incoming sequential (serial) * line signals, punch a 5-level ‘common language"’ chadless paper tape and print the incoming message right on the tape at 100 WPM. Gears are available for slower speed oper- ation at 60 or 75 WPM. Electrical code reading contacts offer parallel-wire output for control of auxiliary equipment. For high speed cross-office message relaying, this non- printing tape punch is available to receive sequential (serial) signals and perforate a ‘‘common language’’ chadless* paper tape at 200 WPM. Gears are available for slower speed operation at 60, 75 or 100 WPM. This component also features parallel-wire output for control of auxiliary equipment. This non-printing tape punch will receive parallel-wire signals from business machines or similar type equipment and perforate a ‘‘common language"’ chadless* paper tape at any speed up to 200 WPM. The tape reader component of the RT Set will read tape from any of the above tape punch components and transmit either sequential (serial) or parallel-wire signals at 200 WPM. Gears are available for slower speed operation at 60, 75 or 100 WPM. Twin-shaft design offers facilities for accept- ing and translating parallel-wire signals for sequential transmission. A pivoted tape sensing device ‘reads’ the last punched character in the tape and automatically stops transmission. *"'Chadless"' tape is standard 11/16 in. communications tape in which the “chad” per- forations remain hinged to the tape. This Teletype feature eliminates the chad dis- posal problem. Vibration Mountings.!n i each RT med fac itate smooth ; A WIDE RANGE OF APPLICATIONS Automatic Message Handling & Routing. For high speed cross-office-relaying of messages through: auto- matic switching centers, the RT Set wil provide the facilities for receiving incoming signals and relaying them cross-office to another RT Set for retransmission ever a selected line. Speed Converter. The RT Set will serve as an auto- matic link between sending and receiving equipment operating at different speeds, e.g., a sending station transmitting at 60 WPM can be linked to a receiving station operating at 100 WPM. Intermediate Message Storage. Permits an incoming message to be received and stored temporarily when the outgoing line is busy. The RT Set will receive the mes- sage on tape, store the tape and automatically transmit the information coded in it to ihe outgoing tine. Business Machine-Communications Linkage. The RT Set will accept 5-leve! parallel-wire signals from com- puters, calculators, punched card equipment or similar type business machines; translate the signals into se- quential form and transmit them over standard com- munication lines to similar equipment in other locations. Automatic Accumulation of Data from IDP equip- ment for transmission over standard communication lines may be accomplished by linking one RT Set to each out- put unitin.the DP system. These in turn can be directed to relay the data to a central RT Set which will transmit on a continuous basis, thus allowing maximum use of line time. Control of Automated Factory Equipment. The RT Set will provide an automatic linkage between incoming control data and signal-operated factory equipment. Reader portion may be activated to read-out continuously or character-by-character as the associated factory equip- ment calls for it. Field Operational Control. The RT Set makes possible direct reception of 5-level parallel-wire- transmission from field: telemetering stations for unattended auto- matic relay over standard communication lines to a central or remote evaluation and control station.

Accessory reading contacts enable 5-level parallel- wire output to control auxiliary equipment. EQUIPMENT Teletype Model 28 equipment is a dynamic new line of communica- tions equipment, offering a new “‘high"' in speed, dependability and flexibility of operation. These new units will cruise at 100 words per minute, are attractively styled, quiet in operation and need only a minimum of maintenance. Under average operating conditions, Model 28 units need lubrication only once or twice a year. Gears are available for slower speed operation at 60 or 75 WPM where desired. Components for Systems Manufacturers, too. Tape punching and tape reading components used in the self-contained units shown here are available to systems manufacturers for integration with their equipment. For Business, Industry & Military. |n business, industry and the military, Model 28 units are the center of more efficient communica- tions plans. Thus, whether your needs involve printing copy, punching tape or reading tape, there is a Model 28 unit to serve you. Teletype Corporation's applications engineers will be pleased to discuss these needs at your convenience. This service is offered without obligation, of course.
