4、Product function
4.1 Switched output DO
4.1.1Switched output DO illustrate
The switch output DO, has level mode, pulse mode, follow mode (follow DI only).Type C relay
output (+ normally closed) and single output supports maximum load (contact capacity) of 30V/10A
or 250V/10A.
Each DO output design has an output indicator lamp (red LED indicator) indicating a broken output
port.When the LED indicator is on, the relay is engaged (often on, often closed off); when the LED
indicator is off, the relay is not engaged (often off, often closed
on).
Fig 4-1-1 The Switch outputs the DO interface
4.1.2 Switch output DO mode settings
（1）Level mode
Output according to the level set by the user, the switch characteristics is similar to the function
of self-locking switch.
（2）Pulse mode
After the switch output DO is opened, after keeping the set pulse width time (unit ms), the
switch output DO is automatically closed.Pulse width setting range 50~65535 (default 50).
（3）Follow mode
After the user sets the following mode, then set the following input terminal.The switch output
DO is consistent with the DI input.
Note: Multiple switch output DO terminals can be set to follow one DI input terminal, and one
switch output DO terminal cannot be set to follow multiple DI inputs.

4.2 Unit address
4.2.1 unit address
Device address composition: hardware address + software offset address
Fig 4-2-1 unit address
Unit address Default i: 32 (hardware address 31 + software address 1 = Unit address 32).
Unit address :Set range：1～247.
Hardware address: implemented by the dial switch (5-bit) dialing setting (factory default is 31).
Software address: implemented by "offset address" by configuration tool software (factory
default is 1).
Example：
If the hardware address is set to5,The Software address is set to113,so Unit address is 118.
4.2.2 Hardware address (code dial switch)

Hardware address: dial switch can switch different hardware addresses, binary indicates the 5-bit
dial switch.The "5" direction indicates low, and the "1" direction indicates high.Hardware address
range adjustable range 0~31.
Description:
Example 1：Set the hardware address 0, with binary encoding.
Fig 4-2-3 Hardware address 0
Example 2：Set the hardware address 8, with binary encoding.
Fig 4-2-4 Hardware Address 8
Example 3：Set the hardware address 31, with a binary encoding.
Fig 4-2-5 Hardware Address 31
Hardware address, can be customized according to the actual situation, setting method as shown
in the above example.
If multiple devices are required to connect to a single RS232, a single bus can be hung on up to
32 devices only through the hardware address (set the hardware address).If you need to connect a
single RS232 with greater than 32 devices, up to 247 devices on a single bus by setting the software
address (offset address).
After changing the address, the new address requires a power restart before taking effect.

4.2.3 Software address (offset address)
Software address: Users can set it differently according to the scene.The software address is set to
1~224 (Unit address:1~247) and the default software address is 1.
After changing the address, the new address requires a power restart before taking effect.
Changing the software address shall be implemented by using the configuration tool software, as
shown in Fig:
