KEPServerEX5 Help
By selecting a specific NIC interface, users will be able to force the driver to send all Ethernet communication through
the specified NIC. When a NIC is selected, the normal operating system bind order is completely bypassed. This
ensures that users have control over how the network operates and thus eliminates any guesswork.
The selections shown in the Network Adapter drop-down menu depend on three things: the network configuration
settings, the number of unique NICs installed in the PC and the number of unique IPs assigned to the NICs. In order to
force the operating system to create the bind order selection, select Default as the network adapter. This allows the
driver to use the operating system's normal bind order to set the NIC that will be used.
Important: Always select the Default condition if unsure of which NIC to use. Similarly, the Default condition is
recommended if an Ethernet based device is being used and this feature is exposed through a product upgrade.
Note: With the server's online full-time operation, these parameters can be changed at any time. Utilize the User
Manager to restrict access rights to server features and prevent operators from changing the parameters. Keep in mind
that changes made to this parameter can temporarily disrupt communications.
Channel Properties - Manual RTS Flow Control
The Flow Control selection of RTS Manual allows the server to control the operation of the RTS line for use with external
devices (such as radio modems) that require additional timing to properly initiate communications.
