FEDERAL COMMUNICATIONS COMMISSION INTERFERENCE STATEMENT
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of
the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/ TV technician for help.
CAUTION:
Any changes or modifications not expressly approved by the grantee of this device could void the
user's authority to operate the equipment.

Duration in Scanning
Parameter # 0x88
This parameter sets the maximum time decode processing continues during a scan attempt. It is
programmable in 0.1 second increments from 0.50 to 25.5 seconds.
To set a duration in scanning, scan the bar code below. Next scan threeNumeric Bar Codes in
appendixthat correspond to the desired on time. Single digit numbers must have a leading zero. For example,
to set an on time of 0.5 seconds, scan the bar code below, then scan the "0", "0" and "5" bar codes; to set an
on time of 10.5 seconds, scan the bar code below, then scan the "1", "0" and "5" bar codes. To change the

Power Mode
Parameter # 0x80
This parameter determines the power mode of the engine.
In Low Power mode, the scan engine enters into a low power consumption Sleep power state
whenever possible (provided all WAKEUP commands were released). SeePower Management .
In Continuous Power mode, the scan engine remains in the Awake state after each decode attempt (see
Power Management).
The Sleep and Awake commands (see SLEEP and WAKEUP) can be used to change the power state in
either the Low Power mode or the Continuous Power mode.

（Level）Key Holding
Press the button to trigger the reading, release the button to end the reading. Reading success or reading

（Pulse）Single Key Trigger
Detects the change of the key level (Maintain 30ms, depending on the product )to start reading, and then
detects the change of the key level (Maintain 30ms, depending on the product )again to end reading. Reading
success or reading time over a single reading time will end the reading.
ContinuousMode
The reading engine performs continuous work. Reading success or reading time over a single reading
time will end the reading. More than the specified time will automatically trigger the next reading.
Automatic Induction Mode
In automatic induction mode,the scan engine detects the brightness of the surroundings. Trigger reading
when the brightness changes. Reading success or reading time over a single reading time will end the reading.
Regardless of the last success or failure to read, re-enter the detection of the surrounding environment
brightness.
Host
Through the command to trigger the scan engine to read, also through the command to trigger the scan
engine to end reading. Reading success or reading time over a single reading time will end the reading.
Note: Key Trigger(Level and Pulse) still valid in other modes

If you select EVEN parity, the parity bit has a value 0 or 1, based on data, to ensure that an even number
of 1 bits is contained in the coded character.

Select MARK parity and the parity bit is always 1.

Software Handshaking
Parameter # 0x9F
This parameter offers control of the data transmission process in addition to that offered by
hardware handshaking. Hardware handshaking is always enabled and cannot be disabled by the
user.
Disable ACK/NAK Handshaking
When this option is selected, the scan engine neither generates nor expects ACK/NAK handshaking
packets.
Disable ACK/NAK
(0x00)
Enable ACK/NAK Handshaking
When this option is selected, after transmitting data, the scan engine expects either an ACK or NAK
response from the host. The scan engine also sends ACKs or NAKs messages to the host.
The scan engine waits up to the programmable Host Serial Response Time-out to receive an ACK or
NAK. If the scan engine does not get a response in this time, it resends its data up to two times before
discarding the data and declaring a transmit error.

Decode Data Packet Format
Parameter # 0xEE
This parameter selects whether decoded data is transmitted in raw format (unpacketed), or transmitted
with the packet format as defined by the serial protocol.
If the raw format is selected, ACK/NAK handshaking is disabled for decode data.

Host Serial Response Time-out
Parameter # 0x9B
This parameter specifies how long the scan engine waits for an ACK or NAK before resending. Also, if the
scan engine wants to send, and the host has already been granted permission to send, the scan engine waits
for the designated time-out before declaring an error.
The delay period can range from 0.0 to 9.9 seconds in 0.1 second increments. After scanning the bar
code below, scan two Numeric Bar Codes in appendix. Values less than 10 require a leading zero. To change
the selection or cancel an incorrect entry, scan Cancel in appendix.
Host Serial Response Time-out
(Default: 2.0 sec.)
Stop Bit Select
Parameter # 0x9D
The stop bit(s) at the end of each transmitted character marks the end of transmission of one character
and prepares the receiving device for the next character in the serial data stream. Set the number of stop bits
(one or two) to match host device requirements.
*1 Stop Bit

Intercharacter Delay
Parameter # 0x6E
The intercharacter delay gives the host system time to service its receiver and perform other tasks
between characters. Select the intercharacter delay option matching host requirements. The delay period can
range from no delay to 99 msec in 1 msec increments. After scanning the bar code below, scan two Numeric
Bar Codes in appendix to set the desired time-out. To change the selection or cancel an incorrect entry, scan
Cancel in appendix.

(Default: 0 sec.)
Host Character Time-out
Parameter # 0xEF
This parameter determines the maximum time the scan engine waits between characters transmitted by
the host before discarding the received data and declaring an error. The time-out is set in 0.01 second
increments from 0.01 seconds to 0.99 seconds. After scanning the bar code below, scan two Numeric Bar
Codes in appendixtoset the desired time-out. To change the selection or cancel an incorrect entry, scan
Cancel in appendix.
