For those drivers that support it, the RTS Manual selection enables the setting of three timing parameters. These
settings will only appear if the driver in use supports RTS Manual.
 Raise the RTS line controls how long the RTS line will be high before any data is transmitted from the
communications port. The time entered is in milliseconds and has a valid range of 0 to 2550 milliseconds. The
default is 10 milliseconds.
 Drop the RTS line controls how long the RTS line will be held high after any data is transmitted from the
communications port. The time entered is in milliseconds and has a valid range of 0 to 2550 milliseconds. The
default is 10 milliseconds.
 Poll Delay allows a delay to be introduced between each communication request. Some radio modems need a
defined amount of settling time before the next transmission can occur. The Poll Delay is used to configure that
delay. The time entered is in milliseconds and has a valid range of 0 to 2550 milliseconds. The default is 10
milliseconds.
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 specific server features in order to prevent operators from changing the
parameters.
Channel Properties - Modem
If Modem Support has been selected for the application, users must select the modem they intend to use for the
channel. The Channel Properties - Modem dialog is used to select a modem from the list that are configured for the PC,
set its properties and enter Phonebook Tags. Once the modem has been selected, its settings must be configured to
match that of the target device. For more information on Modem Configuration , refer to
Using a Modem in the
Server Project .
Once the modem has been properly configured, users can begin using modem tags directly in their application to set
the desired phone number to dial. Users can also establish a list of phone numbers that can be seen as OPC tags from
the OPC client application. The Phonebook Tags, once configured, can be used to automatically dial a desired number
simply by writing anything to the tag. To enter a Phonebook Tag, click on the Phonebook button.
