Note:
Make sure that near station is
transmitting non-null data during initial
acquisition or you may get an invalid
acquisition lock.
Note: After initial acquisition, a
continuous 24-hour period is required
for the software to determine and store
an accurate round-trip time estimation.
If a brief signal loss or power outage
should occur after the 24-hour period,
the unit will maintain the correct round-
trip time. However, if there is a long
signal loss or power outage, the software
must go through a new acquisition lock

5.12.5 Operation
This section identifies some additional procedures useful in operating
the VPCMA-70.
5.12.5.1 Configuring VPCMA-70 Remote Control
The VPCMA-70 may be operated remotely using user-provided SNMP
Manager application software loaded on a computer that is connected
to the Ethernet connector on the rear panel, once the SYSTEM network
access parameters have been configured. To operate in this manner,
perform the following procedures.
1. Ensure the SNMP Manager application software is loaded
and operational on the Remote Controller Computer.
2. Ensure the Remote Controller Computer is connected
properly.
