Example:
smask [mask value]
Description
This command enables you to configure relay output activation status when there is
power fail occurring on power 1 or power 2, or when the switch is being selected as
the master switch.
Bit 0 corresponds to Power1, bit 1 corresponds to Power 2 and bit 3 corresponds to
master switch indicator. If the mask bit of that power(s)(bit 0 and bit 1) or master
switch indicator (bit 2) is specified by being set up as 1, when there is a power fail
occurring on Power(s), or when the switch is selected as master switch, the
corresponding relay output will be activated.
The mask value is in hexadecimal format that represents the 8 bits corresponding
binary numbers, it can be either in the form of i nitiating “0X” plus a suffix of the
hexadecimal number or eliminating “0X”; simply the hexadecimal number itself. If a
mask value is not specified, the “smask” command will display previous assigned
mask value.
To assign a mask value for activating relay output when there is communication loss
occurring on the port(s), please refer to Appendix G, Table – 5.
