Western Telematic AFS-16-1 manual Port Mode Parameters

Basic Configuration

•Sequence Disconnect: Enables/Disables and configures the Resident Disconnect command. This offers the option to disable the Sequence Disconnect, select a one character format or a three character format. (Default = One Character.)

•Inactivity Timeout: Enables and selects the Timeout Period for this port. If enabled, the Serial Port will disconnect when no additional data activity is detected for the duration of the timeout period. (Default = 5 Minutes.)

•Command Echo: Enables/Disables command echo. When disabled, commands sent to the Serial Port will still be invoked, but keystrokes will not be displayed. (Default = On.)

•Accept Break: Determines whether the port will accept breaks received from the attached device. When enabled, breaks received at the port will be passed. When disabled, breaks will be refused at this port. (Default = On.)

Port Mode Parameters:

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

•Port Mode: The operation mode for this port. (Default = Normal Mode)

Depending on the Port Mode selected, the AFS-16 will also allow the definition of additional parameters 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: Permits access to command mode. When 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 available in Normal Mode, but Modem Mode also allows definition of a Hang-Up String, Reset String, and Initialization String:

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 string that can initialize a modem to settings required by your application. (Default = AT&C1&D2S0=1&B1&H1&R2)

Modem Hang-Up String: Although the AFS-16 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.)

Periodic Reset Value: Determines how often the Reset String will be sent to the modem at this port. (15 Minutes.)

Note: When communicating with the AFS-16 via modem, these parameters will not be changed until after you exit command mode and disconnect.
