2.1. IP Addressing

The TCP3 Converter has two network connections. The host connection can be configured to use either
DHCP or Static IP addresses to the building's network. The Printer connection is always configured for
DHCP but users can configure the exact IP address provided so it can match a printer configured with a
static IP address.

2.2. Static IP Host Addressing

In this discussion we will assume that a network printer which was already operating on the network
with a static IP address of 192.168.1.10 as shown in Figure 2.1. That printer will now be connected to
TCP3.
Figure 2.1.: Network configuration before introduction of TCP3
A TCP3 Converter will be installed between the switch and the printer. When installing TCP3 we often
need to maintain the network relationship between the existing printer and the print driver installed on
the user's workstation. As a result TCP3 should be configured to use the printer's original IP address
192.168.1.10.
The printer must now be configured with a different IP address. TCP3 is configured to provide the printer
its address using DHCP. It is further configured to always issue the printer an IP of 192.168.50.100. If the
printer is configured for DHCP it will receive this address at each power up and at each DHCP renewal. If
the printer is not capable of DHCP and is configured with a static IP address, that exact address will need
to be entered on the TCP3 Network page.
Note if TCP3 is placed on a 192.168.50.xx host network, the converter will automatically change the default
printer address assigned via DHCP to 192.168.60.100.

2.3. DHCP Host Addressing

In this example the printer is configured for DHCP and has a MAC based IP address reservation on the
DHCP server so it always receives the same IP address. When the printer reaches out to the building
router, its DHCP controller issues the printer an IP address 192.168.1.10.
As with the preceding static IP address discussion, when installing TCP3 we often need to maintain the
existing network relationship between the printer and the print driver installed on the user's workstation.
