6. LW2 Programmer's Reference
6.3. Network Configuration
6.3.1. Query the Current IP Status
Description: IP address settings can be queried as follows.
Format
Command {IP_STAT=?}
Response (IP_STAT=<type>;<ip_address>;
<subnet_mask>;<gateway_addr>)CrLf
Legend:
<type>:
<ip_addr>:
<subnet_mask>:
<gateway_addr>:
Explanation: The device has a static (fix) IP address: 192.168.0.100; the subnet mask is 255.255.255.0, the
gateway address is 192.168.0.1.
6.3.2. Set the IP Address
Description: IP address can be set as follows.
Format
Command {IP_ADDRESS=<type>;<ip_address>}
Response (IP_ADDRESS=<type>;<ip_address>)CrLf
Legend:
<type>: 0 = static IP; 1 = DHCP
INFO: The IP address can be queried by typing the "ip_address=?" command. The response contains the
fix IP address that is stored in the device even if DHCP is enabled; in this case, this IP address is not valid.
6.3.3. Set the Subnet Mask
Description: Subnet mask can be set as follows.
Format
Command {IP_NETMASK=<subnet_mask>}
Response (IP_NETMASK=<subnet_mask>)CrLf
Legend:
<subnet_mask>:
INFO: The subnet mask can be queried by typing the "ip_address=?" command. The response contains
the fix IP subnet mask that is stored in the device even if DHCP is enabled; in this case, this IP subnet
mask is not valid.
Example
{ip_stat=?}
(IP_STAT=0;192.168.0.100;
255.255.255.0;192.168.0.1)
0 = static IP; 1 = DHCP.
IP address (four decimal octets separated by dots).
Subnet mask (four decimal octets separated by dots).
Gateway address (four decimal octets separated by dots).
Example
{ip_address=0;192.168.0.110}
(IP_ADDRESS=0;192.168.0.110;)
Example
{ip_netmask=255.255.255.0}
(IP_NETMASK=255.255.255.0)
Four decimal octets separated by dots.

6.3.4. Set the Gateway Address
Description: Gateway address can be set as follows.
Format
Command {IP_GATEWAY=<gateway_addr>}
Response (IP_GATEWAY=<gateway_addr>)CrLf
Legend:
<gateway_addr>:
INFO: The gateway address can be queried by typing the "ip_gateway=?" command. The response contains
the static IP gateway address that is stored in the device even if DHCP is enabled. In that case, the latest
valid gateway address (for static IP) is stored.
6.3.5. Apply Network Settings
Description: Apply the network settings and restart the network interface.
Format
Command {ip_apply}
Response (IP_APPLY)CrLf
6.4. GPIO Configuration
6.4.1. Set Level and Direction for Each Pins
Description: GPIO pins can be configured as follows. See more details about GPIO connector in the section
and about the interface in the section.
Format
Command {GPIO<pin_nr>=<dir>;<level>}
Response (GPIO<pin_nr>=<dir>;<level>)CrLf
Legend:
<pin_nr>:
<dir>:
<level>:
Explanation: GPIO pin 1 is set to output with high level.
INFO: The current GPIO pin configuration can be queried by typing the {GPIO<pin_nr>=?} command.
Example
{ip_gateway=192.168.0.50}
(IP_GATEWAY=192.168.0.50)
Four decimal octets separated by dots.
Example
{ip_apply}
(IP_APPLY)
Example
{gpio1=O;H}
(GPIO1=O;H)
GPIO pin number 1...3
