MT-215232 Insertion Reader

MODES OF OPERATION

The Reader can operate in either unbuffered or buffered mode. The descriptions are as follows:

Unbuffered Mode

When a card is inserted and removed, a read attempt is made during both insertion and removal.
Upon removal of the card if the read is successful, data (including the two sentinel characters) is
sent to the Host. The data is transmitted immediately and not retained in the Reader.

When operating in the unbuffered mode, the Reader does not need to received commands from
the Host in order to transmit data or status characters; however, the Reader does respond to an
“Inquiry Command” by sending status characters. The inquiry command that requests the
transmission of status characters is the ESCAPE (ESC) character followed by the ASCII
character “I”.

The Reader must be turned off before selecting the operating mode. Refer to Section 2 for
switch settings.

Note

The insertion and removal of the card must be done in a
continuous motion. If not, the Reader may not read the encoded
data properly. In that case, the Reader responds by either
transmitting the ASCII character “E” representing an error, or by
not transmitting any character, which indicates that the Reader
has not detected data and the card was not completely inserted.

Buffered Mode

When a card is inserted and removed, a read attempt is made during both insertion and removal.
Upon removal of the card if the read is successful, data (including the two sentinel characters) is
stored in a memory buffer on the Reader and is not transmitted until the Reader receives an
“Inquiry Command” from the Host. This command is the ESCAPE character followed by the
ASCII “I”. The Reader cannot read another card until the buffer is cleared. To clear the buffer,
the Host must transmit the ESCAPE character followed by The ASCII “R”.

The Reader must be turned off before selecting the operating mode. Refer to Section 2 for
switch settings

2

Section 1. Features and Specifications

Note

The insertion and removal of the card must be done in a
continuous motion. If not, the Reader may not read the encoded
data properly. In that case, the Reader responds to an inquiry
command by either transmitting the ASCII character “E””
representing an error, or by just transmitting status characters,
which indicates that the Reader has not detected any data and the
card was not completely inserted.

Sets the Carriage Return (CR). This character is optional. Set SWB1 to ON if CR is to be
implemented and OFF if it is not.

SWB2:

Sets the operating mode of Buffered or Unbuffered. Set SWB2 to ON for Buffered or OFF for
Unbuffered.

SWB3:

Two open collector auxiliary drivers are available to the user. The status of these drivers is
reported by the bytes of information following the transmitted card data. If the drivers are not
used, these status bytes may be suppressed by setting the switch to OFF. The status bytes are
transmitted if the switch is set to ON.

SWB4:

Factory set to ON for “I” and “R”, OFF for “+” and “-” See Section 3, Operation, under Host to
Reader Commands.

SWB5:

Factory set to OFF (must not be changed).

10

Section 2. Installation

SWB6:

Factory set to OFF (for the most reliable operation should not be changed). Reader will read
upon insertion and withdrawal. If set to the ON position, the Reader will read on Insert only.
Data is transmitted upon contact of the rear sensor.

SWB7:

Set to the ON position to jumper the control signals RTS-CTS. Set to OFF is these signals are
implemented by the Host.

SWB8:

Set to the ON position to jumper the control signals DSR-DTR. Set to OFF is these signals are
implemented by the Host.

Notes:

1. In previous versions of the Reader, a switch was used to enable reading either a 5-bit
data format or a 7-bit data format. In this version the function of reading a 7- or 5-bit
format is performed automatically by the firmware.

2. Switches that are factory set must be set in the position indicated when used by the
customer. The Reader is one of a series of products using the same microcontroller. The
factory set switches make the microcontroller function properly in the Reader.

Section 3. Commands, Formats, and Timing

INTERFACE WIRE LIST FOR MT-215232

The interface wire list describes the unit with and without control signals in the buffered and unbuffered
modes, D9 and D25 connectors, and LED connections.

Control Signals

The control signals are defined as: DSR, pin 5; DTR, pin 7; CTS, pin 9; RTS, pin 11.

Without control signals in the unbuffered mode, the card reader will transmit the data immediately upon
removal of the card.

Without control signals in the buffered mode, the card reader will transmit the data upon removal of the
card and immediately after the Host has polled the card reader.

With control signals connected in the unbuffered mode, the unit will signal the Host (RTS goes positive)
when it has a message and wait for the Host to signal that it is ready to accept the data. The Host raises
CTS to a positive level to receive the data, and RTS will return to negative after data has been
transmitted.

With control signals connected in the buffered mode, after the card is removed and polled by the Host,
and the Host signals that it is ready to accept data, the data will be transmitted.

Note

Normally this last configuration is not used if the Host has full command of
the control signals

Power and Connector Mating

The +5 VDC ± 5% at 0.045 Amps power can be obtained from an external power supply or from the Host
(not available on the "D" COM port connector).

The reader mates to a 20 pin connector (P2), and the Host has a "D type" connector (P3) which is
normally designated as Com 1 or Com 2.

LED Connections

It may be desirable to have a visual indication of the reader's status at the reader.

By adding two to three LED's (Light Emitting Diodes) to any of the above cables, this can be
accomplished. Connect the anode of all LED's to +5 VDC.

19

MT-215232 Insertion Reader

Connect the cathode of a green LED to pin P2-18. This LED will illuminate when the card reader is
READY to accept a card.

Connect the cathode of a red LED to pin P2-20. This LED will illuminate when the card reader has
detected an ERROR. It will glow for 2 seconds after the card has been withdrawn if there was an error in
reading any track.

The BUSY indicator is not very useful since it is on only when the ready LED is out.
To use this LED, connect a yellow LED's cathode to P2-16.

Normally the anode is the longer lead on an LED to be connected to +5 VDC. The circuit has a built-in
220 ohm resistor to limit LED current on pins J2-14, J2-16, and J2-18.

TIMING

The Reader is capable of bidirectional communication with the Host. Transmission timing is shown in
Figure 3-4. Each ASCII character is transmitted with 1 start bit, 7 data bits, 1 parity bit, and 1 stop bit.
Logic levels conform to standard RS-232 levels; logic levels are “true” or “1” if the level is low (-9 VDC
(quiescent state)) and “false” or “0” if the level is high (+9 VDC).

Figure 3-4. Transmission Timing

INDICATORS

There are three drivers in the Reader that may function as status indicators. They are:

REAR SENSOR (Pin J2-14): Indicates the presence of a card when it is fully inserted in the

Reader.

ERROR (Pin J2-20): Indicates an unsuccessful read attempt. This indicator remains active for 2.0

seconds.

READY (Pin J2-18): Indicates that the unit is ready to accept a card.

See LED connections above.

Section 3. Commands, Formats, and Timing

USER DRIVERS

There are two user drivers activated or deactivated by commands from the Host, which can be defined in
the Host system as indicators to prompt the operator. For Example, if the Reader sent a message to the
Host indicating that it was not ready to read a card, the Host can turn one driver off. When the Host has
completed a card read process, the driver would be turned back on, and a new transition could occur.
Further applications of the two drivers include such functions as operating solenoids or relays. Ratings
for the two drivers are listed in Section 1 under Specifications. For complete specifications, visit

www.ti.com. Search ULN2003AN. Commands to activate or deactivate these drivers are shown in

Table 3-2.
