Connections and Parameters
You only need to read this section if you have not connected the host PC to
the master workstation.
The master workstation’s COMl or COM2 port must be connected to an
unused COM port of the host PC. For most PCs, this is an RS–232 port and
requires a workstation with an RS–232 COM1 port (Catalog No.
2708–DH5B2L). If the host communications is accomplished using a host
with an RS–422 COM port, then make sure that the workstation was ordered
with an RS–422 port on COM1 (Catalog No. 2708–DH5B4L). The COM2
port (or AUX port) on the workstation cannot be used for host/workstation
communications, but the COM2 or AUX port on the PC can.
The cable required from the workstation to the host PC will be a null modem
cable. A wiring diagram for a null modem cable can be found in the Attended
Workstation User Manual (Catalog No. 2708–ND001). We recommend that
the cable be made from this diagram.
Note: Be sure to select the correct diagram (RS–232 or RS–422).
The workstation that will be used for host communications must be
configured to be a “MASTER” or a “GATEWAY” type workstation. The
following discussion is for those who have not already configured their
workstation as a master for interaction with NM.
The following paragraphs assume some knowledge of the configuration
menus on a workstation. For more information on the configuration menus,
refer to the Attended Workstation User Manual (Catalog No. 2708–800).
Note: The Master workstation will not communicate with the host if the
Master workstation has been left in the configuration menus. You MUST
press the EXIT key several times to exit menus after you have configured the
proper parameters.
The recommended workstation configuration is illustrated below. Mandatory
