2 Define an IP Address for each of up to eight reference hosts. If you
define less then eight reference hosts, set the unused fields to
“0.0.0.0”.
3 Assign a Link number (0–99) to the Xenta 527-NPR. Use the fol-
lowing guidelines when assigning the Link number:
• If the Xenta 527-NPR’s DLA feature will not be used, ensure
that you define a link number that is unique to this device
(that is, no other device on the I/NET network can use the
same link number).
• If necessary, you can use the same link number as one or more
other NPRs or Xenta 527/527-NPRs on the I/NET network by
enabling DLA in each device. In this case, use the
Site param-
eter (described below) to assign each device a unique Site
address.
4 If you intend to enable DLA in this Xenta 527-NPR, assign a Site
number (0–63) to this device. Ensure that this number is unique
among all NPRs and Xenta 527/527-NPRs sharing the same Link
number. An I/NET device using a different Link number can
duplicate this device’s Site number without conflict.
If you do not enable the DLA function, this parameter’s setting will
be ignored.
5 Enter the Xenta 527-NPR’s Station number (0–63). Use the fol-
lowing guidelines when assigning the Station number:
• Define a Station number that is unique among all other
devices on the I/NET controller LAN (that is, no two devices
on a single controller LAN can use the same Station number).
• The Station number can be the same as that of a device
attached to another controller LAN. For example, the NPR at
Site 2 of a distributed link can have the same station number
as any device at Site 1 of the distributed link.
6 If necessary, enable distributed link architecture (DLA) function-
ality in this device by setting the DLA control to Yes. When using
the DLA feature, remember to define a unique Site number for this
device. Refer to the TCON300, I/NET Seven Technical Reference
Guide for more in-depth information about DLA.Set the Baudrate
at which the Xenta 527-NPR will communicate with devices on
the I/NET controller LAN. Ensure you set this parameter to match
Note
I/NET host workstations do not provide the same distributed link
capabilities as DLA-enabled NPRs and Xenta 527/527-NPRs. You
cannot duplicate a host workstation’s link address in an NPR, Xenta
527/527-NPR, or any other device on the I/NET network.
