Changing the update rate
It may be required to change the update rate on a sensor, that is
how often it sends information back to the PI54 system. A high
update rate will give frequent information updates, but the
sensor will use more battery power. If you need your batteries to
last as long as possible, you must consider lowering the update
rate.
• A low update rate will provide you with fewer information
updates, but the battery will last very long.
• A high update rate will give you frequent information
updates, but the battery will run out faster.
All sensors are provided from Simrad with a default update rate
setting. In some cases you may find that this update rate does
not suit your operational needs. This is a decision you have to
make depending on the local fishing conditions.
How to change the sensor setup
To change the sensor setup, you can call your local Simrad
dealer, or you can do it yourself if you have the proper
equipment, training and the PI Configurator software.
The P I Configurator application is provided to enable local
sensor configuration. In order to perform this configuration, you
will need a personal computer (desktop or laptop) running
Microsoft® Windows® 2000 or Windows XP®, and a special
cable.
Special configuration of PI Spread
The P I Spread sensor is always used with a PI Remote sensor,
and these must be configured in a pair in order to make the
transverse communication link work properly. In order to allow
for a dual Spread application, you can use two predefined
configurations: P I Spread 1 and/or PI Spread 2.
The Remote sensors are available pre-programmed for these
two pairs, and the sensors are identified as Remote 1 and
Remote 2.
The two pairs must b e configured as follows:
Configuration Spread sensor Remote sensor
PI Spread 1 PI Spread (*) Remote 1
PI Spread 2 PI Spread (*) Remote 2
(*) = The same PI Spread sensor is used for both configur-
ations. By default, it is programmed for PI Spread 1.Ifyou
wish to use it for PI Spread 2, you must re-- configure it using
the PI Configurator application.
