6 Development tips
This appendix includes some development tips in some cases not
specific for a special type of fishery transceiver in other cases very
specific for either the TT -3020C, the TT-3028CM or the TT-3022D
Fishery transceiver.
•
The password described in the document and entered into the
transceiver using the "SE -D N" command must NOT be con-
fused with the password found in Capsat Message Terminal
program. These are 2 different passwords.
•
Developer using the terminal command "DA -B" must be
aware of the limitation in transmitting user defined reports. Us -
ing the "DA" command without "-o" - that specifies that this is a
position report - will result in a "Bad Parameter(s)" error if the 2
significant bits of the first byte transmitted to the transceiver is
binary 01B i.e. 01xxxxxxB - hex value 40H - 7FH.
The reason is that without a position in the report the first byte
send to the transceiver is byte 6 of the first packet in an Inmar-
sat data report. The 2 significant bits in byte 6 is the category
field described in detail in section 2.1.
•
A printer must always be attached to the transceiver otherwise
the memory will be filled up with spool files of not printed
messages and the transceiver will BEEP.
•
In TT-3022D it is possible to switch printing off using the ter-
minal command “SE -Z PRINTER=OFF”
•
In TT-3022D it is possible to switch beeping off using the ter-
minal command “SE -Z BEEP=OFF”
•
Routing of received messages must be configured before i n-
stalling the transceiver. Routing should be set to memory as it
