This document describes both the Facit 4046 punch and the Facit 4047 Reader/Punch Combination. lt includes detailed operating information, interconnection details and interfacing

1 . I N T R O D U C T I O N

The Facit 4046 is a paper tape punch for punching 5 to g track tapes. Five track is normally used to punch telextapes and g-track mostly for punching NC-programs. The punching speed is 60 characters per second.

The Facit 4047 is a reader/punch combination. lt can read and punch 5 to 8 track tapes. The punching speed is 60 characters per second and the reading speed is 120 characters per second. Both units are designed as stand alone units for table top mounting. _{Two standard l/O ports are available}_{with CCITT} V 24/RS-232-C serial interface.

Facit 4046/4047 has a buffer of 3.5 K capacity. The buffer can be shared between the two l/O ports.

Code conversion can be pertormed. The codes included are the two used NC codes ISO and EIA and the nationalversions of the telexcode.

A small keyboard and status display are incorporated at the top of the unit; with this all operating system parameters may be quickly and easily entered with no necessity to change pc board DIP switch settings. The status display clearly indicates the unit's current operating status, and also shows simple error messages.

The Facit 4046 is shown in fig. 1. The blank tape is contained on a standard spool at the top rear of the unit, with the tape feed and punch mechanism housed under a cover towards the front of the machine. A semi-transparent lid covers the tape spool during normal operation, and the amount of tape left on the spool can easily be seen without raising the lid.

The chad box is located at the front left of the unit and may b e r e m o v e d b y p u l l i n g i t o u t f r o m t h e t o p .

The operator's keyboard and status display are situated on t o p o f t h e u n i t i n f r o n t o f t h e l i d .

The mains ON/OFF switch, supply fuses and l/O connectors are fitted on the rear panel of the unit.

The Facit 4047 Reader/Punch Combination is shown in fig. 2. The reader head is mounted at the front of the unit next to the chad box.

2-2 Punch Tape Handling

The tape path through the punch is shown in fig- 3. The

blank tape leaves the spool and passes around a pulley on the

tape guide arm. The guide arm applies a progressively acting

brake which operates on the tape bobbin. This operates to ensure that tape fed through the punch is maintained at a constant tension to ensure accuracy and consistency of punching.

3. OPERATION

An overall block diagram of the Facit 4046/4047 is shown in f i g . 6 .

T h e u n i t i s i n t e l l i g e n t a n d a l l p r o g r a m m i n g f u n c t i o n s a r e p e r -formed by entries made on the built-in keyboard.

All program parameters are held in RAM, and a battery is incorporated on the interface board to preserve the memory contents when the unit is switched off. The battery capacity is sufficient to retain the memory contents for several years.

3.1 Punch Buffer

The overall operation of the punch, and the control of incoming data, is performed by the buffer. Data can be entered via Chan-nel 1 or ChanChan-nel 2, or both simultaneously. Whichever channel receives data first, assumes priority over the other.

The buffer's total capacity (3.5 K) is shared between Channels 1 and 2 according to the buffer stop address selected for channel 1 , in t h e P r o g r a m m o d e ( s e e s e c t i o n 5 ) . E a c h ' b u f f e r ' a c c e p t s data from its source until full; an instruction is then sent to the source to stop transmission (see section 3.3).

The required code conversion of the incoming data is per-formed prior to reading into the buffer; data in the buffer is therefore always in the correct version for direct punching out. 3.2 Punching Out Data

Whichever channel has assumed priority for incoming data keeps this priority when punching data.

Data transfer from buffer to punch is controlled and selected in the Program mode (see section 5).

3.3 Buffer Status Signalling

The acceptance of incoming data via each channel is controlled separately by the Full or Empty status of its associated part of the buffer.

The buffer Full or Empty condition is indicated either by X-ON/ X-OFF protocol or Ready/Busy status signalling, selectable separately for each channel in the Program mode. (See section 5 ) .

3.4 Punch Speed

The punching speed is 60 characters per second. 3.5 Time Out

l f d a t a is s e n t to b o t h c h a n n e l s s i m u l t a n e o u s l y , t h e c h a n n e l receiving data first assumes priority and starts punching. An End of Message character or a Time Out selected in program m o d e (s e e s e l e c t i o n 5 ) c a n c h a n g e p r i o r i t y t o t h e o t h e r c h a n n e l . The Time Out function is explained fully in section 7 3.

3.6 Tape Reader (Facit M7 reader/punch combination onlyl

Where a reader is included on the unit, data read from a pun-ched tape is transmitted via channel 1 or channel 2. When the reader is started from the keyboard (start key) data is always transmitted via channel 1. When the reader is started remote, using the start reader code (see table 6, page 16), data can be transmitted via channel 1 or 2 depending on the channel used

to send the staft reader code, The channel not affected by read-ing can accept data for punching.

lf reading is attempted while data for punching remains in any of the buffers for channel 1 or 2, readings is inhibited and BUSY is displayed. Reading can start when the existing contents are punched and the channel buffer is empty. Reading takes place at a speed of 120 characters per second.

The reader stops when the Stop key is depressed, a stop reader code is received (either sent over the line or read on the tape), or when the tape end is reached.

The transmission continues until the buffer is empty even if the reader stops due to any of the conditions above. The transmis-sion can be controlled using the XON/XOFF protocol (see table 5, page 15, program mode 3/4). Sending the code DC3 will stop transmission and the code DC1 will start transmission.

All the functions of the Facit 4046 /4047 are controiled from a small keyboard _{located on the control panel. A digital readout} consisting of four 7-segment displays is located above the keyboard.

Each key (except _{the [0] key) has two functions. In normal use} the upper functions (printed _{on the keys)}_{are applicable,}_{and the} display shows the operating status of the unit.

When the [PRGR] key is depressed, the unit enters the program mode, and the lower function of each key then applies. The keyboard is used to enter numeric programming data, and the display shows the Program mode values. Programming is described in section 5.

The keyboard functions in normal use are explained in the following tables. Most of the keys operate only with the unit Off-line, and some keys are functional only when the tape reader is present.

When the mains supply is initially switched on, the unit goes Off-line, and OFF appears in the display.

4.1 Key Functions (Facit 4045)

The keys described in Tabie t have functions only when the unit i s O f f - l i n e . W h e n O n - l i n e , t h e o n l y fu n c t i o n a l _{k e y is t h e [OFF}L ] key (Table 2). The display shows the function initiated by each key when depressed.

8. TEST MODE

When the [TEST] key is depressed in the Off-line mode, the unit enters the Test mode and the display shows TEST-Depressing the [* j key then selects the first of seven test r o u t i n e s , ( t h e d i s p l a y s h o w s 1 ) . Depressing _{t h e [TEST] key} then starts the first test routine. lf this routine is completed

without failure, the display then changes to 2, and depression

of the ITEST] key starts the second test routine- This procedure is continued until all seven test routines are c o m p l e t e d .

Any test routine may be entered by depressing _{the [*] key}

a n u m b e r o f t i m e s u n t i l t h e d e s i r e d test routine number appears in the display. This test is then started by depressing t f r e [TESTJ key.

The test routine may be exited at any time by depressing the

A f a u l t o r f a i l u r e i n a n y test routine is shown on the display.

Gombination

Onlyl

This test enables the test tape punched in Test [llode 4 to be read by the reader. Note that the Reader Code Conversion (Program Mode 9l must be set to the same value used in Test M o d e 4 .

With the tape placed in the reader, depressing the [TEST]

key starts the reader and checks the punched data. The reader stops when an incorrect character is read, and the display shows that character as its decimal value. Depressing the [*] key will show the correct value in the

display-Testing is continued by depressing the ITEST] key, and reading continues until the whole tape is read. The unit then enters Test Mode 6.

8.6 Test Mode 6 - Single Track Punching

This test enables individual punch pins to be checked separately. Depressing the ITEST] key causes a blank tape to feed through the punch; iny one track 1 to 8 may now be punched continuously by depressing the required number key 1 to B. The track being punched can be changed at any

time by depressing another number key.
