Reset Battery Usage Indicator
The Reset Battery Usage Indicator task should be performed immediately after replacing the VR2C’s
internal Lithium D cell with a fresh battery. This causes the battery usage indicator to be reset to 0% used.
Performing this task at any other time other than immediately after battery replacement will result in
incorrect battery usage indicator results.
3.1.9.3
RS485 Termination
If RS485 communication is being used with long cables and high baud rates (cable longer than 200m and
baud rate higher than 57600, for instance), the system may require that RS485 terminations be enabled in
order to have a reliable communication link between the VR2C and
the RS485 host. If this is the case, RS485 termination can be
enabled by selecting the RS485 Termination configuration box
within the
Serial Options
window (under the
Set Device Options
icon). Enabling RS485 Termination causes the VR2C to
consume more power while communicating with the host
and should only be used if necessary.
If there are multiple VR2C receivers attached to a single cable deployment, ensure that only the furthest
VR2C on the cable has RS485 Terminations enabled.
Enabling RS485 Termination causes VR2C to
consume more power when communicating
with the system host processor
– only enable if
necessary.
If multiple VR2C receivers are attached to a
single cable deployment, then
only the
furthest
VR2C on the cable should have
RS485 Terminations enabled.
