Connection Timeout
This parameter specifies the time that the driver will wait for a connection to be made with a device. Depending
on network load, the connect time may vary with each connection attempt. The valid range is 1 to 30 seconds.
The default setting is 3 seconds.
Request Timeout
This parameter specifies the time that the driver will wait on a response from the device before giving up and
going on to the next request. Longer timeouts only affect performance if a device is not responding. The valid
range is 100 to 30000 milliseconds. The default setting is 2000 milliseconds.
Retry Attempts
This parameter specifies the number of times that the driver will retry a message before giving up and going on
to the next message. The valid range is 1 to 10. The default setting is 2.
Device IDs
Up to 1024 devices may be defined on a given channel. The device ID is formatted as YYY.YYY.YYY.YYY, where
YYY designates the device's IP address. Each YYY byte should be in the range of 0 to 255. If the device supports
host name resolution, the device ID may also be specified as a standard UNC/DNS name.
Note:
For NetLink users, NetLink communication parameters (such as IP Address, Subnet Mask, and Baud Rate) can be
configured using the NetLink Configuration utility. This application is located in the server's Utilities sub-
directory and can be launched using the Start menu shortcut.
