1.2 Application
The contactless smart card reader module UIC681 is mainly to support the contactless
payment systems. The small footprint size of the module makes it easily to integrate to the
current transaction system such as Point-of-Sale terminal, kiosk, and vending machine
station as the part of the system. The module communicates with a host computer or
terminal using a standard RS-232, USB or TTL interface.
At the meantime, UIC681 offers both RS232 and TTL magnetic stripe decoder pass-thru
function to allow the terminal to share the same input port with other peripheral devices.
The TTL interface output is in the F2F decoder data emulation. This benefits the existing
system without change its hardware configuration to catch up the future payment trend.

3.6 Communication
• RS232 Interface Data Output
Synchronization
The interface receives and transmits serial asynchronous data at voltage levels
compatible with the RS232 specification.
Baud Rate
9600 BPS default (optional: 1200/2400/4800/9600/19200/38400/56000/115.2K BPS)
• RS232 Interface Pass Through
Baud Rate
9600 BPS default (optional: 1200/2400/4800/9600/19200/38400 BPS)
• USB Interface
Compatible with USB specification 1.1
• F2F TTL Interface (Optional)
Each track has the clock and data. Please refer to command set for the detail setting.
• Transmission Protocol
The user may select from three different protocols: Protocol 0, 1, and 2.
Upon reset, the reader sends the power-on response “:”, depending upon the
configuration setting. The reader then configures itself to the protocol of the first
command from the host. From this point on, the protocol is unchangeable until a reset
occurs.
Protocol 0
In Protocol 0, all characters are transmitted and received using exactly the characters
listed in section 4. There are no headers and Block Check Characters (BCC). Protocol
0 presumes no transmission errors. If the host detects an error, it may request a
retransmission.
Table 3-5. Example for Protocol 0
Protocol 1
In Protocol 1, all messages are preceded by the ASCII character <STX> and
terminated with the ASCII character <ETX>, followed by a one byte <BCC>.
<BCC> is an XOR of the 7 data bits, excluding parity, of each character in the entire
message, including <STX>.
Format: <STX><MESSAGE><ETX><BCC>
Host Command Reader Response Comment
P Ready to read
^ Reader ACK
UIC681 Programmer’s Manual UDN PM063-U Rev. 4
3-5
where STX=02Hex and ETX=03Hex.
Table 3-6. Example for Protocol 1
Protocol 2
In Protocol 2, all messages are preceded by the ASCII character <SOH>, followed by a
one byte reader address, two bytes character count and terminated with a one byte
<BCC>.
The <BCC> is an XOR of the characters (8 bits) in the entire message, including
<SOH>.
Format: <SOH><ADDRESS><00Hex><COUNT><MESSAGE><BCC>
Table 3-7. Example for Protocol 2
The <ADDRESS> field is for a multi-reader system. This function is not currently
supported. The recommended value for this field is NULL (00Hex), however, any value
will work.
For Protocols 1 and 2, if the reader detects an error in an incoming transmission, it will
respond with a “Communications Error” message. If the host detects a transmission
error, it may request a retransmission. Besides, all protocols enforce a 10mSec timeout
between characters.
• Self – Arm Mode
The default reader configuration is the “Self-Arm Mode”, which allows the payment
cards (Including PayPass Magnetic Stripe, VISA MSD, ExpressPay card and the
general magnetic stripe credit cards) reading functions to run automatically, reporting
the card data to the host without instruction from the host.
In the Self-Arm Mode, the reader also can accept commands from host. However, the
reader can be configured to only “Host Polled Mode” by disabling Self-Arm Mode. The
“Host Polled Mode” allows the card reading functions to run by commands.
• Transmission Format
In Self-ARM mode, the default setting of card data output doesn’t include the protocol
envelope code. The user can turn on the envelope code by utilized the configuration
command – SE, TO. (Please refer to the appendix section of UIC681 Configuration
Guide)

• <DC2> (12H) – RS232 pass through enable
COMMENT Enable RS232 data Pass Through (PT) function temporarily.
FORMAT The command characters are followed by an ASCII ‘P’ to enable the
RS232 pass through function. It is only valid in RS232 model.
NOTE Once the pass through mode is enabled, UIC681 passes all data
between COM1 and COM2 and do nothing. Power cycling (if the default
of PT is disable) or send the string “<DC2>P<DC2>a<DC2>s<DC2>S”
brings UIC681 back to normal operation. Before sending this command,
the user must assure the PT function is desired.
• <CAN> (18H) – Clear Data Buffer
COMMENT Clear the card data buffer.
• <7FH> – Warm Reset
COMMENT Abort all current actions and cause the device to execute all initialization
functions. The device will respond as it would for a "power up" cycle, but
always returning a “:” (3AH). This operation will take at least 3 seconds.
• <09H> – Configuration Setting
COMMENT This command is used to set configuration in EEPROM.
FORMAT The command (09H) is followed by the configuration data format to set
the configuration in EEPROM. Please see “UIC681 Configuration Guide”

Section5: Application Example
The default setting of UIC681 reader, Self-ARM mode, is mainly to simplify the process
for the host that doesn’t need to communicate to each other. In this situation, the UIC681
acts like a general magnetic stripe card reader whenever it senses the card, it will try to
decode the card data automatically and send the decoded data to the host if the process is
successful. Otherwise, no information is sent out.
If the application would like to take whole control on the reader, it is recommended
using the “Host Polled” mode instead of the “Self-ARM” mode. It can be done by either
sending “Self-ARM” disable command or changing default setting in the reader
configuration.
Once UIC681 receives the Self-ARM disable command, H0 (see the command
description section), it turns off auto-read function and waits for the “Arm-to-Read”
command, P, for next transaction. Since the Self-ARM disable command won’t change the
EEPROM setting, UIC681 will turn back to Self-ARM for next power cycling. Besides, the
Self-ARM enable command, H1, can also bring UIC681 back to Self-ARM.
To disable Self-ARM mode permanently, the host needs to set the EEPROM value of
UIC681. The configuration command SAx (x = E or D, see the Configuration Guide) saves
the setting into the EEPROM of UIC681 and keep the value until next changed.
Meanwhile, it is recommended using the Protocol 2 (USI2) for “host polled” application
because USI2 contains the header, message counter and block check character. It is better
than Protocol 0 (USI0) and Protocol 1 (USI1) to prevent the data to be misinterpreted but
needs more redundant bytes.

Host Polled Application Example
A. UIC681 setting changed
In this example, it assumes UIC681 is in factory default and the user would like to change it
to protocol USI2 and Self-ARM disable.
This process should be done only once to set the UIC681 to the proper state.
Due to the EEPROM life limitation, it is recommended that don’t change the
EEPROM value very frequently. Normally, the configuration setting has done in the
factory production stage, please contact UIC Sales representative for more detail
information.
Initial State
1. Send the configuration command to set
UIC681 to protocol 2.
2. Send the configuration command to set
UIC681 to Self-ARM disable.
Done

B. Operation Example
In this example, it assumes UIC681 is in protocol USI2 and Self-ARM disable.
After host issues the Arm-to-Read command, UIC681 will check if any payment card in the
reading read zone or any magnetic stripe card swiped (the magnetic stripe reader is
optional device). No matter the card is decoded succeed or failed, it will return ‘^’ to indicate
the card has been read. The host can issue Q, R, S command to retrieve the card data.
