GENERAL DESCRIPTION
This section contains the functional and operational
description of the
CONTROL DATAR FEl19-A Card Reader
Controller.
The card reader controller logic circuitry is mounted on
a single 50-PAK printed wiring board. The controller
interfaces with the A/Q channel of the AB107/AB108 Computer
to control the operation of the card reader and transfer of
the data. Interrupts are also generated within the
controller.
The card reader controller may be accommodated
within the AB107/AB108 Computer or the BT148 Expansion
Enclosure.
The controller provides the following functions:
1. Provides four basic
interrupt signals:
a.
Data Interrupt
b. E~d-of-Operation Interrupt (EOP)'
c. Alarm Interrupt
d.
Common Interrupt
2. Interface signals
3. Timing for interrupt and interface Signals
4. Address decoding
5. Reply and reject
6. Data reading and transfer
7. Program protection
The controller interfaces the Card Reader with the 1784
Computer AQ data channel. Its typical configuration is
shown in Figure 1-1. Data is transferred from the Card
Reader to the lower 12 bits of the Computer A Register
(AOO through All) containing the information for one
1-1

AQ
column of a card. Data bit ADO corresponds to card row 9.
The address of the Card Reader and controller is selected
by inserting jumper plugs in positions Q7 through Q10,
at location 56 on the CARD READER Printed Wiring Assembly.
The jumper plugs are stored in location 15.
Any of 16 different equipment codes may be set up by
these jumper plugs. Refer to Section 3, Installation and
Checkout for details about jumper plug selections and
codes.

2-2
The Wportion of the Qregister (Q11 - Q15) must be all O's for
all Card Reader operations.
The"E portion of the Qregister (Q07 - Q10) defines the Card
Reader Equipment Code. The code is set up by the plugs shown
in Figure 2-4. If the switch settings match bits 07 - 10 of Q,
the equipment responds.
The S-part of the Qregister (005, Q06) must have the following
settings for Director Functions and for Data transfer:
Q05 =1, Q06 = O.
When accompanied by an Equipment Code and either a Read or
Write Signal. a command code defines the operation to be
performed. The Dportion of Q (QOO and QOl) defines the
operation to
be performed by the Controller.
DATA TRANSFER
Read Data (goO = 0, 901 =0, 005 =1, 006 = 0)
When bits QOO, Q01 and 006 are 0, and 005 =1. and they are
accompanied by the Equipment Code and a Read signal, the
Controller
is directed to perform a data transfer. Areject
occurs
if there is no data to be transferred. The Card Reader
rejects when
a. The Card Reader is not ready
b. The computer attempts to input data at a rate
that
exceeds the capabilities of the Card Reader,
that is, Data Status is not set.
c. Protect Violation occurred.
DIRECTOR FUNCTIONS (gOO =1, Q01 = 0, Q05 =1, 006 = 0)
When QOO and Q05 are l's and Q01 and Q06 are O's and they are
accompanied by an Equipment Code and a Write signal, the controller
is directed to perform the fo110wino operations. Director
functions
may be stacked (i.e. two or more functions sent
simultaneously), but
when a function is sent which should be
rejected, the Controller rejects the Director Function.
89637500 B

89637500 B
NOTE
The Card Reader executes and replies to the Clear
function if it is Not Ready, provided that no other
director
bit (except A01) ;s transmitted with it
(bits A02 through AD8 must be zero). Care should
be taken in using this function while the Card Reader
is busy, as this condition results in the operation
being aborted.
Clear Controller (ADD = 1)
This function directs the clearing of all interrupt reQuests and
responses, motion requests, errors, and other logic which may be
cleared. This bit is subordinate to bits A02 through AD7 of the
Director Function.
NDTE
The Card Reader will execute and reply to the Clear
Interrupts function if it is Not Ready, provided that
no other director bit (except ADO) is transmitted with
it (bits AD2 through AD8 must be zero).
Clear Interrupts (AOl = 1)
This function directs that all interrupt requests and their
responses be cleared; it is subordinate to the interrupt
request bits A02 through A04.
Data Interrupt Request (A02 = 1)
This function sets the Data Interrupt Request flag which causes an
interrupt to be generated when information is available. The
interrupt is cleared by a reply to data transfer. The interrupt
request and response is cleared by bit ADO and AD1. Interrupt
Request takes precedence over function" clears.

End of Operation Interrupt ReQuest (A03 = 1)
This function sets the EOP Interrupt Reauest flag. The purpose of this
interrupt
is to notify the computer that the unit is finished with an
operation. The interrupt ReQuest and Response is cleared by bit AOO or
A01. Interrupt Request takes precedence over function clears.
The interrupt may be selected before or during the operation. An
interrupt response does not occur for an operation which terminated
before the selection
was made.
Alarm Interrupt ReQuest (A04 = 1)
This function sets the Alarm interrupt request flag and so enables the
generation of
an interrupt when an Alarm condition exists. These
conditions are listed 1n the Alarm section. An Alarm condition that
exists at the time of the interrupt request immediately provides a response;
if the Alarm condition does not exist at the time of the interrupt request
the interrupt response
is provided as soon as the Alarm condition is
detected.
The Alarm Interrupt Request function is cleared by a Master Clear or
when ADO =. 1, or AOl = 1 with A04 = O.
The interrupt response is cleared by a Master Clear or when AOO =1
or
A01 =1. When the interrupt response is cleared by Director Function
AOO = 1, or AOl = 1, the interrupt request may be reset with the same
operation if A04 =1.
Director functions
AOS and AD6 are not used.
Feed Request (A07 =1)
This function directs the Card Reader to initiate a feed cycle.
If a new Feed Request is issued before EOP occurred. data transfer in
that card is truncated and will continue on the next card being fed.
No EOP interrupt is generated. This function takes precedence over the
clear controller function.
D;re~tor Function A08 is not used; it is accepted by the Controller.
Director Function
A09 throu~h A1S are not used. and are ignored by
the Controller.
89637500 B 2-5

DIRECTOR STATUS (QOO =1,001 = mLEVEl I
When QOO is a 1 and QOl is a O. and a Read signal is present. the
computer is requesting Levell status. The Controller will always
reply to this operation.
Ready (AOO = 1)
This bit indicates that the Ready signal is active on the Card
Reader.
Busy (AOl = 1)
This bit indicates that the Card Reader is busy. The Card Reader
becomes busy when a feed cycle is initiated and remains busy until
an End of Operation occurs.
Interrupt
(A02 = 1)
This bit indicates that an interrupt response was generated by the
controller.
The other status bits must be monitored to determine
the
cause of the interrupt. The controller may generate interrupts
on four different lines due to three different conditions which
may occur at the controller and their logical "OR" function.
a.
Data Interrupt
Data Interrupt will be generated when both the Data Interrupt
Request flag and the Data Status are active.
b. EOP Interrupt
EOP Interrupt will be generated when both the EOP Interrupt
Request flag and the EOP status are active.
c.
Alarm Interrupt
Alarm Interrupt will be generated when both the Alarm Interrupt
Request flag and the Alarm status are active.
d. Common Interrupt
COnlnon Interrupt will be generated when any or any cOnDination
of the Data Interrupt, the EOP Interrupt or the Alarm Interrupt
are generated.
8963-75008

Data (A03 = 1)
This bit indicates that a data transfer may occur, that is data is
available in the controller ready for transfer to the computer. The
status and interrupt drops when data has been transferred to the
computer.
End of Operation (EOP) (AD4 = 1)
This bit indicates that the Card Reader has completed reading a card.
Alann (A05 = 1)
This bit indicates the presence of an alann. Two kinds of alarm
condition can occur:
a.
The Card Reader Ready signal becomes not active. Ready status .
becomes false.
b. When lost Data occurs, no further transfers occur from that card.
The Ready status is unchanged.
lost Data (AD6 = 1)
This bit indicates that data was not transferred out of the Controller
to the computer, before the next column of a card being read appeared.
No further data transfer will occur until Clear Controller is issued.
Protected
(A07 = 1)
This bit indicates that the Controller is in the Protect state.
that is. the Protect, I jumper pl ug is out. The Controller
then accepts only those instructions which have their protect bit
set. All other instructions are rejected. Aprotected instruction
can be used with either a protected or an unprotected Card Reader.
For setting the protect bit see Operation.
Director status is not rejected
if Protected Violation occurred.
Director status
bit A08 is not used and is always zero.
89637500 B 2-7

OPERATION
2-8
Not Ready (A09 = 1)
This bit indicates that sometime during a card cycle there
was a failure in the transport of the card. It is always
the inverse of Ready (bit 00).
Director status bits Ala through A15 are not used and are
always O.
DIRECTOR STATUS (goo =1, gOl = 1), LEVEL 2
The Controller will always accept Director Status, level 2,
but will
load the A-register with the constant 0000
