Teletype M14 TD variant used to read PYTHON one-time key tape -
This RECEIVING TD operates slightly faster than a normal TD - 420rpm shaft
speed but 368 opm (45.5 baud) line speed. This is necessary so that the
key tape can always synchronize with characters from the source tape or
keyboard.

TSEC/HL-1 connection to TSEC/KL-7 via KLX-7/TSEC adapter The TSEC/HL-1 (an ancillary tape reader) senses a five level teletypewriter tape and interprets the signals through a series of relays as a literal signal. One side of the sensing mechanism is electrically tied to common in the TSEC/KL-7 through the keyboard adapter pin A7. Circuits are completed from common in the TSEC/KL-7 through the sensing pins and relays in the tape reader to specific points on the output plug of the TSEC/HL-1. The points on the output plug are wired through a cable and the keyboard adapter to individual key circuits in the TSEC/KL-7. Circuits completed to these individual key circuits effectively simulate a key closure and printing is initiated in the normal manner. |

expressly for shipboard use to provide for automatic off-line encryption
and decryption of teletype traffic. The cryptographic keying variables are
determined by the rotor maze of the associated cipher machine.
Perforated tape previously prepared from incoming radio teletypewriter or CW circuits is fed into the tape reader which actuated the pre-set cipher machine. Output of the cipher machine is converted into teletypewriter code signals by the code converter whose output provides pulses which are used to produce a page copy or a reperforated tape or both. The speed of operation is 50 baud. The complete configuration consists of the following components:

|
FUNCTIONAL DESCRIPTION The AN/UGA-1 is designed to accept multiplexed
output of sixteen (16) channel multiplex equipment and divides it into
sixteen (16) separate channels which are synchronously related to each
other. Output on each channel is in six (6) unit synchronous signal. The
receive portion of the equipment performs companion function. RELATION TO OTHER EQUIPMENT The AN/UGA-1 is designed to be used with but not part of AN/UGC-3() for use on frequency division telegraph systems. TYPE OF DIVISION: Time-division type. TYPE OF OPERATION: Neutral. TYPE OF ACTUATION: DC actuated. NUMBER OF CHANNELS: 16. NUMBER OF WORDS PER MINUTE: 60, 75, 100 words per minute per channel. RELATION OF CHANNELS INPUT AND OUTPUT: The 16 channel inputs and outputs are synchronous in nature and are synchronously related. |
|||
|
The AN/UGA-1 is for specific use with terminal set AN/UGC-3 in a fixed-station operation. The transistorized AN/UGA-1 provides facilities for the operation of AN/UGC-3 with radio equipment AN/FGC-29. The transmitting group accepts a neutral sequential signal of information such as provided by the 16-channel AN/UGC-3. The sequential signal is then converted, and retransmitted in 16 individual channels of information and combines them into a neutral sequential signal that can be utilized by the AN/UGC-3. AN/UGA-1 can change a high speed sequential signal into multiple low speed signals that can be transmitted over conventional radio TTY facilities, in addition to receiving circuits for converting multiple low speed signals into a high speed sequential signal.
For use with standard 60-speed TTY XMTR-DISTR's. |

|
FUNCTIONAL DESCRIPTION: The Telegraph Terminal Set AN/UGC-3 is a transistorized, sixteen (16) channel, time
division, multiplex equipment for fixed station installation. A complete set consists of a transmitting and receiving group. The transmitting group accepts neutral, start-stop signals from up to 16 separate circuits and assembles them in sequential order for multiplex transmission over a single circuit. The receiving group accepts multiplex signals from a distant source, converts them to start-stop, and distributes them to 16 separate circuits. Signals are received from a number of start-stop teletypewriter circuits, stored, and transmitted over common channel. In this process, the message characters from the start-stop circuits are compressed in time so that a character from each of these circuits is transmitted in the time normally required to send one character from a single circuit. The receiving multiplex terminal sorts the compressed signals into their respective circuits and regenerates them into normal length start-stop characters. Adjacent siting of the receiver and transmitter group permits use of the built-in test equipment in both. TYPE OF MULTIPLEXING: Time-division type. TYPE OF FREQUENCY CONTROL: Temperature controlled crystal oscillator. REPETITION RATE: 60 wpm-440 pps; 74 wpm-562.5 pps; 100 wpm-733.69 pps. NUMBER OF CHANNELS: 4, 8, 12 or 16. RELATION TO OTHER EQUIPMENT: In four channel operation, the multiplex signals of the AN/UGC-3 are completely compatible with those of AN/UGC-1 at all speeds and with the AN/FGC-5 at 60 & 75 words per minute. Any standard apparatus using a 7.42 unit code may be employed in the start-stop circuits. All start-stop equipment must have the same operating speeds of 60, 75 or 100 words per minute. The AN/UGC-3 is designed to be used with, but not part of AN/UGA-1. |
|||
|
AN/UGC-3 is a transistorized 16-channel TTY time division multiplex equipment utilizing components and techniques used in the 4-channel equipment (AN/UGC- 1). Used with radio or wire link, and AN/UGA-1. Channel speed: 60, 75, or 100 WPM. Power required: 115 v, 60 cps, 1 ph. |
