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.
  FE 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

Device Low

  This value defines the low address in a range of device addresses. If you are not using a range of device addresses, set this parameter to zero.
  Range: 00 -- FF hexadecimal

Device High

  This value defines the high address in a range of device addresses. If you are not using a range of device addresses, set this parameter to zero.
  Range: 00 -- FF hexadecimal

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

Connect Type

  This parameter determines whether or not the PU is originating or answering the call.
  Range: Originate or Answer

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)
