Basic Configuration

PortModeParameters:

• PortName: Allows you to assign a name to the Setup Port. (Default = undefined.)

• PortMode: Selects the port mode for the Serial port. The port mode can be set to

Normal Mode, Modem Mode or Modem PPP Mode. (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.



NormalMode: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:

 DTROutput: 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.)



 ModemMode: 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:

 ModemResetString: Redefines the modem reset string. The Reset String

can be sent prior to the Initialization string. (Default = ATZ.)

 ModemInitializationString: 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)

 ModemHang-UpString: 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.)

 Reset/NoDialtoneInterval: Determines how often the Reset String will

be sent to the modem at this port and also sets the trigger value for the No

Dialtone Alarm. For more information on the No Dialtone Alarm, please refer

to Section 7.9. (Default = 15 Minutes)

 NoDialtoneAlarmEnable: When this item is "On" the No Dialtone Alarm

can be enabled as described in Section 7.9. When the No Dialtone Alarm is

enabled and properly configured, the VMR/NPS can provide notification if the

unit detects that a phone line connected to a modem installed at this port is

dead. (Default = Off.)

Note: When communicating with the VMR/NPS via modem, these parameters

will not be changed until after you exit command mode and disconnect.
