4 If necessary, enable distributed link architecture (DLA) function-
ality in this device by setting DLA 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.
5 If you enabled DLA in the step above, 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 did not enable the DLA function, you will not be asked to
define a Site number.
6 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.
7 Set the CLan Baudrate at which the Xenta 527-NPR will commu-
nicate with devices on the I/NET controller LAN. Ensure you set
this parameter to match the communication speed of all other
devices on the controller LAN.
8 Set the UDP Port number to any value from 49152 to 65535. The
default setting for this parameter is 50069. Communications over
this port are not encrypted.
9 If necessary, enable encrypted communications. If you answer yes
to this option, perform the following steps:
a Set the Secure UDP Port Number to a value from 49152 to
65535.
b Define an Encryption Key of up to 25 alpha-numeric charac-
ters (this string is case sensitive and there are no restrictions
on what characters you can use).
Note
If you disable DLA functionality by changing the DLA option from
Yes to No in a Xenta 527-NPR, ensure that you also change the
Xenta 527-NPR’s Link address to a unique value. Duplicate link
addresses are not supported in devices that have the DLA function dis-
abled.
