4. Across the top of the screen is displayed the current hardware and software versions. If the IP232 received
a dynamic IP address from a DHCP server, that address will be displayed immediately below the version
numbers.
5. As previously discussed, the IP232 is factory defaulted to DHCP, which means that it expects to be
assigned a “dynamic” IP address. Be aware that a “dynamic” IP address can periodically change for many
reasons, including a power down/up cycle. You may optionally assign the IP232 a permanent “static”
address, if permitted by the network. This will also involve setting values for subnet mask, and default gateway.
These settings can be obtained from your network administrator or Internet service provider. On a local
network, the subnet mask is typically 255.255.255.0 and the default gateway is the IP address of the router.
If the IP232 is programmed to obtain a dynamic IP address from a DHCP server, it will
revert back to 192.168.0.251 if it fails to obtain a dynamic IP address.
6. The “Device Network Name” is useful for selecting between more than one IP232 on the same network. It
has no other use and may be left blank if desired.
7 The IP232 is a network server. This means it listens for and accepts incoming network connections. But it
must know which IP port (1 – 65535) to listen on. Enter the port in the “IP Port to accept connections” box.
The factory default is 2401. This port is recommended, because it is not widely used. You should stay away
from well-known and commonly used ports such as 21, 80, and 8080.
8. Select the baud rate of the connected serial device in the “Serial port baud rate” selection box. Make sure the
serial device is set to the same baud rate.
9. If the connected serial device requires handshaking, select the handshaking method in the “Serial port
handshaking” selection box. If it does not require handshaking, select “None” (default).
Note that while baud rate and handshaking are selectable, the IP232 supports serial
communications only with eight (8) data bits, no parity, and one (1) stop bit.
10.Click “Save Settings” to send the settings to the IP232. They will be stored in memory and the IP232
will reboot.
