2-6 ASMi-450 Installation and Operation Manual
DIP switch S1 allows the user to control the reloading of the desired group of
default parameters. The switch has four sections used for the following
purposes:
• Switch section DEF SP. This section selects the source of the control port
parameters:
ON ASMi-450 uses the default parameters stored in its program
EPROM. The default values are Autobaud, eight data bits,
and no parity.
OFF ASMi-450 uses the user-selected parameters.
Upon first-time operation, you should use the ON position to start the
configuration. You can select this position again to restart with the default
parameters in case the current values are not known, and it is not possible to
communicate with the ASMi-450 through its control port.
The ASMi-450 is shipped with this section set at OFF.
• Switch section DB INT. This section selects the source of the data base
configuration parameters:
ON ASMi-450 uses the default parameters stored in its program
EPROM.
OFF ASMi-450 uses the user-selected parameters.
The ASMi-450 is delivered with the data base loaded with the default
parameters. You can select this position again to restart with the default
parameters in case the current values are not known.
The ASMi-450 is shipped with this section set at OFF.
• Switch section MS/SV. This section is reserved for future features, and
must be always set at ON.
The ASMi-450 is shipped with this section set at ON.
• Switch section PSWD. A password, consisting of up to eight alphanumeric
characters, can be used to prevent unauthorized personnel from using the
ASMi-450 control program. The ASMi-450 is delivered with a default
password, ASMI, but normally the password is selected by the user.
The PSWD section is used to select between the default ASMi-450
password (the ON position) and the user-selected password (the OFF
position). The ASMi-450 address (node number) is also affected by the
setting of the PSWD section: with the jumper set at ON, the node number is
set to 0.
Upon first-time operation, you should use the ON position to start the
configuration. You can select this position again to restart with the default
password and node address 0 in case the current user password was lost.
The ASMi-450 is shipped with this section set at OFF.
