Load Default Values for OTU
LDV=5 - Load the default values
for a freestanding UTMC OTU
outstation.
LDV=8 - Load the default values
for a semi-integral UTMC OTU
outstation, using a serial link to
communicate with the ST700/800
controller.
See LDV command on page 262
for other values.
Where the outstation is only
required to operate as an OTU it
should be initialised using INI=1
prior to the use of this command.
