LFO
Line Feed Off

Disables line feed after the carriage return (no line feed is sent after each card is read).

LF1
Line Feed On

Enables transmission of a line feed character (ASCII code 10) following the carriage return.

ST0

Unit Status is not returned with data.

ST1

Unit Status is returned with data.

ATN

ATteNtion

Causes the Card Reader LOAD ATTENTION lamp to flash. The unit will stop reading cards once
the current card is read.

LOD
LOaD Attention

Causes the LOAD ATTENTION lamp to light. If a LOD command is sent and cards are in the

hopper, the Card Reader will ignore the command.

RES
RESet Unit

Resets the Card Reader to the following default operating parameters: Continuous Feed, Eight Bits,
Parity Off, One Stop Bit, LF Off, Echo Off, ASCII Mode, and Status Off. If a card read
operation is in progress, this command will not be executed until it is completed. Any commands that
follow the RES in a command string will not be lost.

Hexadecimal Commands

l l
XON

The CR-510 supports the XON/XOFF protocol. The hexadecimal value 11 is the XON ASCII
character. An XON command is the only command that will allow card data transmission to resume
once an XOFF command has been issued.

13
XOFF

The Hexadecimal value 13 is the XOFF ASCII character. The XOFF command will cause an

immediate interruption in the transmission of data from the CR-510 to the computer.

13 14

Clear and Reset

The Hexadecimal value 13 followed by a Hex 14 will cause the unit to clear all error conditions and

reset to the following default operation parameters: Demand Feed, Eight Bits, Parity Off, One
Stop Bit, LF Off, Echo Off, ASCII Mode and Status Off. If a card read operation is in progress, this
command will terminate it immediately (a hard reset). All commands and data resident in the
CR-510 memory prior to receipt of the Hard Reset will be flushed. (Also, referred to as DC3 and DC4.)
