323 Card Punch
323 CONTROL PANEL
THE FOLLOWING hubs are located on the punch control panel (Figure lOS): position of the output track. The hubs emit informa-tion in the standard IBM punched-card code form.
These exits are wired to the PUNCH MAGNETS to cause punching. This allows any of the 100 output track magnets that punch the correspondingly numbered columns of the card. These magnets are wired from card code is recoded by a combination of X-and a-bits.
Also, sign control on negative fields is maintained by carrying an X -bit over the low-order position. If the low-order position of a field is zero and the field is negative, a 12-hole would be punched if this position were wired directly to a punch magnet. The sign con-version hubs are provided so that the 12-impulse avail-able from the output track may be converted to the x/a code desired for these positions.
In use, the low-order pOSItIon of any numerical X. Positive numbers pass through without conversion.
Figure 106 illustrates the type of wiring necessary this cycle. The information may also be gangpunched back into the following card. automatically controlled to transfer between X and a time as each card is punched. This allows the separa-tion of the digits 0-9 from the 12- and X-zones. For example, if the character A were wired to the com-mon of aCOLUMN SPLITposition, thenumer ical digit 1 would emerge from the 0-9 hub, and the 12-zone would be available at the 12-11 hub.
Figure 107 illustrates a method of using the COL-UMN SPLIT device to punch an X over the high-order position of a field.
Double-Punch and Blank-Column Detection
The 323 Card Punch is equipped with 20 positions of DPBC detection as a standard feature. Up to 60 addi-tional positions are available as a special feature. By ap-propriate control panel wiring, it is possible to detect the presence of either multiple punches in any single column or the absence of any punch in a column or both.

BC Det Control (blank-column detection control Figure 110.) These hubs provide a means for control of blank column detection. All positions of DPBC are internally connected for blank-column detection.
It is possible to bypass any particular position or posi-tions that are not to be checked for blanks by control panel wiring in the following manner: The BLANK-COLUMN DETECTION CONTROL hub for the last posi-tion, in which blanks are to be checked, is connected by a control panel wire to the BLANK-COLUMN DE-TECTION CONTROL hub preceding the next position which is to be checked for blanks.
If it is necessary to bypass checking for blanks in the last position (position 20 for standard machine), the BC DET CONTROL hub for the last position in which blanks are to be checked must be connected by a control panel wire to the BLANK-COLUMN DETEC-TION CONTROL hub for the last DPBC position.
(Wire 3, Figure 111). Any selection of these hubs must be through co-selectors.

Digit Selector. One digit selector is standard with the 323 punch. It may be used to separate or combine multiple digits. In addition, it may be used to select specific digits from the output track or punch brushes.
When the D I impulse is connected to the common of the digit selector, it becomes a punch digit emitter with a 12 impulse available out of the 12 hub, 11 f rom the same output track data.
If selectors are used, two cards with different formats

When Punch Repeat has been impulsed, the OUT hub on the Punch Control Panel will emit just prior to

A Program Exit wired through a ~ommunication
Channel for the purpose of impulsing Punch Repeat must be wired to the P (Program Exit) IN. Also, the Program Exit that is wired to Punch Repeat must be the same Program Exit that is wired to PUNCH on the prior to punching time of the second card.
More than one additional card can be punched by impulsing Punch Repeat D IN on successive cycles. The number of additional punch cycles can be controlled by the use of Pilot Selectors.
Pu"nch Repeat will maintain its proper status during and numerical punching of alphabetic fields so that they can be wired for DPBC detection.
TIMING CHART
THE PURPOSE of the punch timing chart (Figure "113) is to increase the general knowledge of machine opera-tion and to assist expenenced programmers who must resort to unusual wiring methods to accomplish a de-sired result. A good working knowledge of the machine is necessary before this timing chart can be used ef-fectively.
As shown in Figure 113, the punch cycle has been divided into fourteen equal parts called "Points." The points are numbered on the timing chart in the follow-ing sequence: 12, 11, 0, 1, 2, 3, 4, 5, 6, 7,' 8, 9, 13 and 14. Points 13 and 14 represent the space between cards, and points 12 through 9 correspond to the read-ing and punchread-ing of the card.
A card cycle starts at 14.5 (midway between 14 and points of the selector resulting in incorrect operation.
For example, the timing chart shows that a selector would be damaged if the selector pickup is impulsed from a Pilot Selector COUPLE) and Punch Repeat OUT is wired through the transferred points - two-tenths of a cycle point difference is not provided.
Notes:
fol-lowing cycle just prior to punching time.
