AR-727CM has two way of power supply, one from power jack and one from DB9.
In general usually, The Serial Device has DC power already, so AR-727CM can share
the power with Serial Device. The DB9 pin-4 connect to Power Ground (V-), pin-6
Connect to Power Source (V+). If you power AR-727CM from Adapter, remove the
jumper from JP1.
3. Configuration
3.1 Reset To Factory Default
Press RESET button more than 5 seconds, The
BUSY LED will flash 5 times, then AR-727CM
will restore to Factory Default value. DIPswitch is
OFF, OFF, OFF, OFF position.
IP Address : 192.168.001.127
Gateway IP : 192.168.001.254
Subnet Mask : 255.255.255.000
Serial Port : 9600,N,8,1
TCP Port : 1621
Password : none
DIP Switch position
OFF, OFF, OFF, OFF
3.2 DHCP Function
AR-727CM support Auto Configuration of the
IP and gateway addresses and subnet mask
function, but must make sure the DHCP Server
is active. Switch DIP SW-4 to “ON” position
then power cycle the Device. In begging state
the ACT LED will flashing, After IP has got ACT
LED will off and auto save the new IP address
to EEPROM, Switch DIP SW-4 to “OFF”
position and move DIP SW-1 to “ON” position
then you can get the new IP from Serial port
via Hyper terminal.

3.3 How to configure the IP address assigned to your AR-727CM device?
3.3.1 Get IP address by using Net727i software
Usually, the network of some company don’t built-in the DHCP Server. Therefore, we
can use the following method to get default IP address and modify it. The steps as
follows:
Step 1: Press RESET button more than 5 seconds, The BUSY LED will flash 5 times,
then AR-727CM will restore to Factory Default value.
Step 2: Open explorer, click “My Network Places” and press right key to open Properties.
Step 3: Click “Local Area Connection” and press right key to open Properties.
Then double click Internet Protocol (TCP/IP) to open Properties.
5
Step 4: Click ”Use the following IP address” and enter IP address 192.168.001.64,
Subnet mask 255.255.255.0
Step 5: Click “ok” to exit.
Step 6: Install Net727i.exe into your PC and run Net727i.exe
(Start → Programs → soyal software → Net727i )
6
Step 7: Click “Get” to get default Local IP Address, Gateway, Netmask and TCP Port.
Step 8: Change new address and parameters then click “write”.
Step 9: If AR-727CM connects to soyal controller, please switch DIP Switch position
to OFF, OFF, ON, OFF to RS-485 RUN Mode.
Remark:
(1) How to know PC’s IP Address? (Win98)
Start → execute → enter “winipcfg”.
(2) How to know PC’s IP Address? (Win2000)
Start → Programs → Accessories → Command Prompt → C:\> ipconfig
(3) Please see detailed parameter in next page:
