16-6. Network Settings
16-6-1. Arcnet

OU and MU are configured for ARCNET as below
For the MU and OU to communicate, use the BNC cable to connect an Arcnet port of each
unit. If you want to connect other devices to the Arcnet, use the other Arcnet port of the MU or
the OU. If the MU or the OU is the last device in the network, the other port has to be 75 ohm
terminated. Refer to section 3-2 "Optional Configuration" for Arcnet configuration and
operation manual for HVS-AUX16/32 (Hanabi Auxiliary unit).

Arcnet Setting
The factory default settings for the ARCNET are shown in the table below. Change ARCNET
settings only when if necessary. The settings can be made in the MU SETUP – NETWORK
menu and OU SETUP – NETWORK menu.
If you are configuring one each OU and MU via ARCNET, connect them in P2P (peer-to-peer)
configuration and leave MU and OU to factory default set ID numbers (250 and 1
respectively). Accessible MU ID(s) will be shown under the ACTIVE MU ID item in the menu.
If you want to disconnect the MU from the OU on the Arcnet, select any ID other than shown
in the ACTIVE MU ID block.
Parameters Description Default Range
OU SETUP
ARCNET OU ID Sets Arcnet ID for the OU. 1 1-255
CTRL MU ID Selects MU Arcnet ID controlled by the OU. 250 1-255
MU SETUP ARCNET ID Sets Arcnet ID for the selected MU 250 1-255

Expanding ARCNET Devices
If you are configuring additional OU, MU or other ARCNET devices, different ID numbers will
need to be set for each unit and additional connection cables will be required. Please consult
your FOR-A supplier regarding needed items for your configuration.
Be careful not to use the same ARCNET ID for two different units. If ARCNET ID conflict has
occurred and network communication fails, turn unit power OFF at one of the units in conflict
and disconnect from the network. Power on the conflicting unit and change the ID to a valid
network ID. If you want to change the conflicting MU ID, connect the conflicting MU to the OU
at peer-to-peer and change the MU ID from the OU. Turn all units power off, re-connect all the
units in the system and turn the system power back on to re-configure the network. Note that
new ID will not be valid until units are powered ON again.
<System File Loading>
Before downloading system data from an installed memory card, verify ARCNET ID currently
assigned to OU and MU for operation is the same as in the data being downloaded. If a
conflicting ARCNET ID (one assigned to another OU or MU in the network) is downloaded
and applied, network operation will fail after download is complete.
