  Note: Depending upon your product type, this dialog may vary. This help context covers all possible configuration parameters. If your dialog does not contain certain parameters, they don't apply to the product you are configuring.
  Some options are only available for terminal PUs.
  To add an entry, click on the Add button.
  To delete an entry, select it, then click on the Delete button.

ID

  This is the polling address by which the PU is polled by the device.
  Each time a PU is added, the configuration editor automatically assigns this value. If you choose to change the assigned value, make certain it matches the actual controller.
  FF is reserved for dial-up connections.
  Range: C1 -- FF

NAU Name

  This optional field enables you to assign a name to the PU. NAU names must be unique to the unit.
  Range: Up to eight alphanumeric characters

Initial State

  This field sets the PU's initial state at system startup.
  Range: Enabled or Disabled

XID

  This field enables you to assign a PU XID. The unit uses XIDs to establish and negotiate PU application sessions. If the PU cannot respond to an XID request from the Host, the unit uses this assigned XID value.
  To solicit an XID from a PU, or if your PUs are type 1 or 2.1, leave the XID field blank.
  Range: 8 hexadecimal numbers

Destination

  Click inside this field to select the appropriate destination. If the destination does not appear in the list, you may add it though the Destination Editor.
  If you are using XID mapping, and the unit is answering the call, you may leave this field set to None.
  If the PU is originating the call or you are using MAC/SAP addressing, you must select a destination.
  Range: Any device in the pull-down list

Port

  Select the port through which the unit communicates with the destination device.
  Range: 1 -- 8

DLCI

  Enter the primary DLCI the PU uses to contact the destination device. If your connection is back-to-back, enter 32.
  If you do not specify a DLCI, the unit sends a broadcast test frame over all available routes to determine the best route. To reduce the cost of these broadcasts, define the primary DLCI.
  Range: 16 -- 1023

SAP

  This is the SAP address of the selected destination device. This field is automatically defined once the destination is selected.
  Range: 04 -- F8 (in increments of 4)

SPC

  This special connect address defines the direction of the session setup. A TISO port will default to Answer, while the HISO port will default to Originate.
  Range: Originate or Answer

GPA

  This parameter defines the hexadecimal group poll address for the control unit. This parameter only applies to Burroughs poll/select (group polling).
  Range: 0 ~ FF (0 = no group polling)

IWD

  This parameter defines whether the control unit has a captive or freestanding device associated with it.
  It must be set to Yes for NCR MTS and Burroughs poll/select protocols.
  If set to No, only one device may be associated with this control unit.
  If set to Yes, one or more devices may be associated with this control unit.
  Range: Yes or No

Protocol

  This parameter defines the protocol of the ISO-asynchronous connected device.
  Range: NCRMTS, BPS (Burroughs poll/select), NCR796, or NCR270

Devices

  To add a device, click on the Add button.
  The hexadecimal device address defines the attached ISO-Async devices.
  Range: 00 ~ FF
