IPV4 Configuration
Important considerations for Dynamic Host Configuration Protocol (DHCP)
Use a DHCP server to automatically assign IP addresses to devices (see step 4, in
the procedure that follows). Before you complete the communication settings for
the device, note the following:
• Ensure that your DHCP server complies with the minimum requirements of
the DHCP RFC2132 standard to supply an IP address, subnet mask setting,
and default gateway setting.
• Do not configure InTouch DX devices to use DHCP on a network that does
not support DHCP. Otherwise, each device performs an address request every
five seconds for an indefinite period. These requests can adversely affect
network performance.
• To change the IP address of a device that uses DHCP: change the address on
the network; assign the address to the device; and then remove the address
from the DHCP pool so that another device cannot use it.
• If you remove a device that uses DHCP, you can reuse its former IP address.
To configure the device to use the IPV4 address format:
1. Tap Settings.
2. Tap Communication Settings.
3. Tap IPV4.
4. Address Mode—do one of the following:
–Tap DHCP. Go to step 8.
–Tap Static. Go to the next step.
5. IP Address: Enter the IP address for this device (the default value is 127.0.0.1)
and tap Enter.
6. Subnet Mask: Enter the IP address for the sub-network (the default value is
255.255.255.0) and tap Enter.
7. Gateway: Enter the gateway IP address (the default value is 127.0.0.2) and tap
Enter.
