Configuration
2. (Optional). Communication parameters for Host and Field ports can be configured in the Advanced
Port Configuration window (click the Advanced button):
a. Choose the desired protocol and configure the communication parameters. Default
communication parameters for the Rosemount 2460 ports are shown in Tab le 4 -1 and Table 4-2
on page 60.
The Advanced Port Configuration
(1)
window lets you change from standard port configuration to a
non-standard configuration. This is a useful option if, for example, the Rosemount 2460 System
Hub is connected to a host system that requires manual port configuration. Then you can
configure protocol and communication parameters to match the host. Non-standard settings
may also be needed in case field devices connected to different field ports use different
communication parameters such as baud rate. Then each port can be configured independently
from the other ports.
Non-standard settings may also be required in case the system hub is located far away from the
host since maximum communication speed for RS232 and RS485 depends on the cable length.
Some emulation protocols use the same type of modem card. Therefore, you may need to specify
communication protocol and configure parameters for the particular protocol to be used.
For Field Ports the Reply timeout and Number of retries parameters can be adjusted in case a
connected field device responds slowly to queries from the Rosemount 2460. The default setting
is sufficient in most cases.
For Host Ports the Min response time and Max response time define the time slot in which a
response from the Rosemount 2460 will be sent to a host system. If needed, you may change
these parameters to match the requirements for a particular host system.
b. Click the Apply button to save the current configuration.
c. Click the OK button to return to the Rosemount 2460 System Hub Configuration window.
3. In the Rosemount 2460 System Hub Configuration window click the Next button to continue the
installation procedure of the Rosemount 2460 System Hub.
1. Some modems must be configured with DIP switches, see “Modem cards” on page 148.
