2.1.11 Dot Energy
The printing energy used to write each dot determines how
black the printout is.
The dot energy is selected by DIP switch setting. When the dot
energy is set to normal, printing head energy is lower and
printer lifetime is prolonged.
2.1.12 Selftest Printout
Selftest printout is initiated when OK and FEED is pressed at
powerup. The selftest printout prints character set and DIP
switch setting. Normal Remote Alarm operation is resumed after
printout. If OK is pressed for 15 seconds the Remote Alarm is
softreset and selftest printout is initiated.
2.1.13 NMEA 0183 Sentence Input
When configured for NMEA 0183 input/output the NMEA 0183
input can be connected to a navigator with a NMEA 0183 output.
The input is optical isolated and only two wires are to be
connected. Both inverted TTL (+5V/0V) and bipolar (-15-0V/1V-
15V) signal levels are accepted. The NMEA 0183 input is optical
isolated when jumper W2 is in position 1-2 (low).
The TT-3042D automatic detects if a NMEA 0183 navigator output
has been connected. Standard NMEA 0183 messages are read,
position and velocity data extracted and transferred to the
transceiver.
NMEA 0183 sentences read are: GGA, GLL, VTG, GXP, GDP,
GOP, GLP, TGA, HDT and HSC. Please refer to navigator manual
for further information.
