Description
LOCAL
• • • • • • • • •
In LOCAL mode, the AOP mounts directly onto one SED2 VSD
and then scans its RS-232 and RS-485 ports to establish com-
munications with the first port that answers. You can control the
SED2 VSD by accessing all normal SED2 and AOP internal
parameters. LOCAL mode is the default of the AOP on initial
power-up or after a reset.
MASTER
• • • • • • • • •
In MASTER mode, the AOP can control up to 31 SED2 VSDs
which connect in a multi-drop arrangement. An operator can
control each SED2 VSD by accessing all normal SED2 and AOP
internal parameters. In MASTER mode, the network controls the
SED2 VSDs either individually or by broadcast operation. A
broadcast operation can simultaneously start or stop all net-
worked SED2 VSDs.
INTERNAL
• • • • • • •
In the INTERNAL mode, you can access all parameter sets
which are stored within the AOPs hardware. You can not access
any parameter sets stored in the SED2 VSDs.
In the INTERNAL mode, the main menu includes an Engineering
item. This menu item allows you to view a USS message log of
the last 1k bytes of messages between the AOP and the con-
nected SED2 VSDs.
SLAVE
•
In SLAVE mode, the AOP communicates with a PC using the
AOP Desk Mounting Kit. In this configuration, the AOP acts as a
slave to the PC. At the PC, you can upload and access para-
meter sets or the AOP internal parameter set as a USS address,
numbered 1 through 10.
PC mode
•
In PC mode, the AOP is used with a panel mounting set to con-
trol a network of SED2 VSDs. In this configuration, the AOP acts
as an RS-232/RS-485 converter. In PC mode, you can modify
only the communications baud rate function.
