Basic Configuration
PortModeParameters:
• PortName: Allows you to assign a name to the Setup Port. (Default = undefined.)
• PortMode: The operation mode for this port. (Default = Normal Mode)
Depending on the Port Mode selected, the VMR/NPS will display additional prompts
listed below. In the Text Interface, these parameters are accessible via a submenu,
which will only be active when the appropriate port mode is selected. In the Web
Browser Interface, fields will be "grayed out" unless the corresponding port mode is
selected.
NormalMode:Allows communication with a local PC and permits access to
command mode. When the Normal Mode is selected, the following mode-
specific parameter can also be defined:
DTROutput: Determines how DTR will react when the port disconnects. DTR
can be held low, held high, or pulsed for 0.5 seconds and then held high.
(Default = Pulse.)
ModemMode: Permits access to command mode and simplifies connection
to an external modem. Modem Mode ports can perform all functions normally
available in Normal Mode, but Modem Mode also allows definition of the
following, additional parameters:
ResetString: Redefines the modem reset string. The Reset String can be
sent prior to the Initialization string. (Default = ATZ.)
InitializationString: Defines a command string that can be sent to
initialize a modem to settings required by your application. (Default =
AT&C1&D2S0=1&B1&H1&R2)
Hang-UpString: Although the VMR/NPS will pulse the DTR line to hang-
up an attached modem, the Hang-Up string is often useful for controlling
modems that do not use the DTR line. (Default = undefined.)
PeriodicResetValue: Determines how often the Reset String will be sent to
the modem at this port.
Note: When communicating with the VMR/NPS via modem, these parameters
will not be changed until after you exit command mode and disconnect.
