Using the
JC-MER-CXB
Planning Form B in Appendix A, add to
your right-side screen data with
the ARCNET Subnet Address
(Column 1) and IP Address (Column 2) of each Metasys Ethernet
device to
be connected.
Enter
these two addresses on the same line
above the “000” terminating flag at the end of the
list
. The # symbol
means that the text following the # is a remark. The following is an
example for three Metasys Ethernet
devices
:
1 192.168.20.91
2 192.168.20.23
3 192.168.20.56
Save the
configuration screen
data by
simultaneously pressing the Ctrl
and "K" keys, then release both keys and press the "S" key to
save the
data and
automatically reboot the JC-MER-CXB with the new settings
.
The R
X
LED
on the ARCNET port should
glow
and the ACT
LED
should
f
lash as the ARCNET port
searches for
other ARCNET nodes.
Note: When entering IP addresses, care should be taken to avoid a
trailing space which, although invisible onscreen, will
nevertheless cause the address to be incorrect.
Connecting Field Cables
1. Connect the ARCNET cable from the Metasys N1 ARCNET
subnet to the port on
the JC-MER-CXB
. If there is activity on the
subnet, t
hen the
ACT LED on
th
e unit
should
glow
.
2. Connect the cable from the Ethernet network to the
unit's
Ethernet
port. If the cabling is correct and there is a
working
Ethernet
device on the other end of the cable, the green Link
LED should glow. If so, proceed to the next step.
There is a provision for setting the Extended Timeout value of the
ARCNET subnet. The default is 0
(meaning normal timeouts)
and in
the majority of applications, it should be left at 0. Extended timeouts
are only required on large fiber optic installations
where the ARCNET
network diameter exceeds 5 km.
The JC-MER-CXB connects to N1 ARCNET via coaxial as described
in Appendix E. The unit connects to N1 Ethernet via an RJ-45 jack.
Verify no configuration errors exist by typing
cat router.err
.
