6.4 Tilt Theory
The 865 Release contains a tilt sensor that will allow the operator to determine the general orientation of
the release. The standard sensor will indicate when the release is tilted more than 25 degrees from
vertical.
When the tilt function is enabled and the release is tilted more than 25 degrees, it will respond to an
interrogation with the normal respond ping, plus four additional pings 200 milliseconds apart (if not
tilted, the unit will respond with the normal single ping).
The tilt function can be turned on and turned off via an acoustic command (see section 7.1) and the
power up state can be defined via the serial setup ( see section 7.5).
7.0 CHANGING THE RELEASE SETUP
The model 865 release is shipped from the factory with all operating parameters set to the values
specified by the customer. These values are visible on the waterproof label attached to the outside of the
release, and thus in most instances, these values will not need to be changed by the operator.
If , however, changes are required (to any parameter EXCEPT the receive frequency which is only set
at the factory), they may be easily made via the RS-232 programming cable A-855-171 (see drawing in
the back of the manual for a schematic of the required cable) supplied with the release.
To connect the serial cable, open the housing to gain access to the electronics boards. Connect the
cable to the board via J13 (see figure 5.3). Connect the DB-9 connector on the other end of the cable
to the a computer running a terminal emulator (Procomm, Hyperterminal etc). Set the communications
to the appropriate serial port (normally 1 or 2), with the following operating parameters:
Baud Rate:
9600
Parity: (N)one
Data Bits: 8
Start Bits: 1
Handshake: None
Turn on the release, or if the unit is already on press the “Reset” switch SW1 on the board. The
following opening screen should appear:
