In the preceding diagram, the 3270 client software on one of the PCs accesses the
BiSync host by using the IP address of the DT-6061 and the TCP port number
associated with a TN-3270 server instance. This TN-3270 server instance connects
through the UMI to a line on the BiSync host, which requires proper configuration of the
TN-3270 application, the UMI module, and the BNS-2000 node (aspects of which pertain
to both the BHI and UMI). The
DT-6061 TN-3270 Server Application User’s Manual
describes all the necessary configuration steps for a network with the same topology as
the one shown here.
2.1 Checking Configuration Data
Since this is a complex configuration prone to errors in many places, let’s begin by
verifying that everything is correctly configured. To do so, we need to separately
examine each participating networking element.
2.1.1
3270 Client
Check that the 3270 client software on the PC is configured with the correct IP address,
TCP port number, and terminal type. Based on this example network, the configured IP
address should be 192.168.8.250 (the IP address of the DT-6061 that the TN3270
application resides on). The TCP port is determined by the instance number (the default
setting) or it can be administered. In this case, the administered TCP port number
(shown in the green bubble above the DT-6061) is 40000, which is the value that should
be configured on the 3270 client software. The terminal type on the client must match
the terminal type configured on the TN-3270 application (shown in the next section),
“IBM-3278-2” in this case.
