Chapter 1
Overview
Delta Fixed Barcode Scanner is capable to read 1D and 2D barcode. The communication
interface is RS485 that supports Modbus and Private protocol. The Modbus mode supports
parameter setting and barcode transmission, and private mode supports barcode transmission
only.

2.1 Input and Output
DFS150-485 has 1 isolated input and 2 isolated output, both of them share an isolated common
ground COM. The input is bi-direction, so that the COM can be connected to either ground or
power while output is not connected.

2.2 RS485
RS485 is an asynchronous protocols, half duplex serial port, and the communication interface for
control and barcode transition. It supports Modbus and Private protocols, both will be described in
detail in chapter 4.
It supports the setting for baud rate, data bit length, parity type, and stop bit length. The setting will
be effective after the next reboot with sending a software reset command or the power on reset.
More details may be found in chapter 3. Flow control such as XON/OFF and RTS/CTS are not
supported. The features and default setting are shown below.
2.2.1 Features
Asynchronous transmissions and receptions.
Baud rates: 9,600bps to 115200bps.
Parity type: None, Even, Odd.
Data length: 7 or 8 bits data.
Stop bit length: 1 or 2 bits times.

2.3 LED & Beeper
Beeper makes a long beep during power up and short beep for successful barcode decoding. The
beeper can be switch on/off by setting the control register. When it is switched off, it will beep
during power up, but not during successful decoding.
There are four LEDs on DFS, LED_PWR, LED_OUT,LED_IN and LED_COMM. Their behavior
is described as below:
LED_PWR: It indicates power status, always on when connected to power.
LED_OUT: It set to represent the OUT0 to confirm whether the system is in the busy period,
decoding barcode.
LED_IN: It indicates whether the trigger is valid and acts when exposing.
LED_COMM: It represents DFS is in the start-up communication period after power on, and the
communication traffic of RS485 when it is acting.
Figure 5 shows the behavior of LEDs and beeper after power on.

Power On
DFS150-485 operation in three-modes, Master Private, Master Modbus and Slave Modbus
modes. All these modes are valid after a start-up communication period followed the power on
period T_(Power_on). During the start-up communication period T_(startup_comm), operation
mode is fixed in Slave Modbus ASCII mode, all triggers are invalid. This period can be extended
by sending arbitrary valid command to the scanner, and user may communicate with scanner in
the extension communication period as long as they want until reboot or send software reset
command.
If no command is received within T_(startup_comm), ten seconds, it will switch to the scan mode
set by user previously. The default scan mode is Slave Modbus ASCII mode. After set all
parameters, DFS150-485 provides two ways to update the setting: reboot or send software reset
command. The behaviors after T_(startup_comm) are shown below.

Chapter 4
Operation Mode
DFS150-485 provides user with three operating modes and two data types: Master Private,
Master Modbus and Slave Modbus modes, and ASCII or RTU. The operation mode and data type
can be set by the control register as shown in Scan Mode, Data type and Trigger Source
Table 7. Scan mode, Data type and Trigger Source Setting.
Master Private Mode provides user to get barcode without any protocol, it will send data to Slave
devices automatically after successful decoding. It triggered by I/O or continuous mode.
Master Modbus Mode is used with PLC mostly. It provides user to receive barcode by I/O trigger
or continuous trigger with Modbus protocol.
Slave Modbus Mode, the parameter can only be set in this mode, supports parameter setting and
bar code transmission. The function code includes 0x03 - Read Holding Registers, 0x06 -
Preset Single Register, and 0x10 - Preset Multiple Registers. User can generate triggers through
I/O, command, or using continuous trigger mode to get the barcode with Modbus protocol.
