Step 1
a) Connect an RS-232 serial cable to an available serial communication port (COMM Port) on your
computer. Note that CA-47 cables cn connect to 25 pin COMM ports or 9 pin COMM ports.
b) Connect the other end of the RS-232 cable to Net232’s CONFIG port (PORT 1).

Step 2
a) Cycle Net232’s power switch “Off,” then “On.”
b) In the NetScan Configuration Utility, check (
3) the on-screen box that states, “I have performed the
actions described above.”
Step 3
Basic information regarding TCP/IP Addressing for Net232 is presented below. If you
have any difficulty regarding address settings, please contact your network
administrator.
a) Review the following terminology as needed, then proceed to step 3b.
Protocol
The Net232 uses TCP/IP (Transport Control Protocol/Internet Protocol) for communications over the
ethernet. You can access Net232-connected devices from virtually anywhere in the world since the World
Wide Web uses this same protocol.
TCP/IP addressing consists of three parameters: the IP address, the Sub-net Mask, and the Gateway
Address. Each of these parameters consists of four different numbers which range from 0 to 255. The
numbers are typically represented in a dotted decimal format, for example: 192.88.247.11.
IP Address
The IP (Internet Protocol) address is unique to one specific device on the network, and can not be shared by
any other device on the network. The only restrictions on the IP address are:
1) the first number must be between 127 and 255
2) the last number must be between 1 and 254.
Sub-net Mask
The Sub-net Mask determines how many addresses are on the network. Note that Class C networks consist
of up to 256 addresses; and are quite common. For a Class C Network the Sub-net Mask would be
255.255.255.0. All computers on the network must have the same subnet mask.
