5.6.3.8 Select Switching Operation Mode (PMOI/PMOS)
The switching mode can be set via these device specific commands to
Individual switching mode (PMOI) or to Simultaneous switching mode (PMOS),
please refer to chapter 5.1.4.
<STX>PMOI<checksum><ETX> i.e. <STX>PMOI35<ETX>
and
<STX>PMOS<checksum><ETX> i.e. <STX>PMOS3F<ETX>
The device confirms both commands with an <ACK> if the command is accepted and
with a <NAK> otherwise. The commands are rejected in Local Mode and the PMOS
command is rejected in Remote Mode or Auto Mode if the preconditions for Simul-
taneous switching mode are not given. This means that all members of all groups
(with two or more members) have to be in the same switch position; i.e. all switch
modules of a group are switched to the primary or to the secondary input port
(chapter 5.1.4).
5.6.3.9 Select Power Supply Monitoring Mode (PMP0/PMP1)
With these device specific commands the power supply monitoring can be
disabled (PMP0) or enabled (PMP1).
If disabled, the reporting of all power supply events via the query command AM (or
AMA) (please refer to chapter 5.6.3.2) including the Q command (chapter 5.6.3.1) is
suppressed.
<STX>PMP0<checksum><ETX> i.e. <STX>PMP01D<ETX>
and
<STX>PMP1<checksum><ETX> i.e. <STX>PMP11E<ETX>
The device confirms both commands with an <ACK> if the command is accepted and
with a <NAK> if the device is in Local Mode.
Note:
 The successful execution of these commands modifies bit 1 of the SNMP
.errorEnableMask (chapter 5.9.4.4.2).
