6. Configuration
6.1. Non-configurable Parts
Normally when an altimeter is ordered from
Tritech International Ltd
a configuration sheet
is filled out with the customer to specify the function of the device exactly. Some of these
configurations are controlled through dip switches (detailed below), however, the following
list of parts are determined by a particular hardware configuration.
Note
It is possible to replace or alter some of these components, however, doing so
would normally require the altimeter to be returned to
Tritech International Ltd
for a re-build. Contact details are at the start of this manual if such a change
is desired.
The following aspects are usually fixed at manufacture for the life of the product:
Physical hardware
Casing, connector type and wiring scheme.
Analogue Voltage
Control
Fixed at: none, 5V or 10V - altering this would require a new
electronics block.
Serial/Current output
Fixed at: 4-20mA, RS232 or RS485 - altering this would require
a new communications board.
Ping rate
The default ping rate for free-running mode is approximately
10Hz for a PA500 and 7Hz for a PA200 (other ping rates are
available).
Velocity of Sound
Set to either 1470m·s
-1
or 1473m·s
-1
6.2. Dip Switch Settings
Note
The switch positions shown here are the generic settings which apply to all
altimeters. There are other combinations which relate to specific customer's
requirements and these are not shown. If in doubt contact
Tritech International
Ltd
prior to making any changes.
