TackTick T122 NMEA interface not repeating DPT input

[Chuck - Raymarine - Moderator]

allene,

I have transmitted the sentences which you have provided to the T122's NMEA 0183 IN2 port and have verified that the TackTick display is reported the received depth value. Unfortunately, it appears that the T122 did not transmit DPT sentence along with the other NMEA 0183 sentences transmitted by the T122. A problem report has been submitted to seek correction of this problem. Until such time as a correction is issued, it is recommended that this problem be worked around paralleling the NMEA 0183 output from the NMEA 0183 source of depth data and then interfaced the paralleled output to the NMEA 0183 input port of the NMEA 0183 listener which in turn requires this data.

With respect to the RMC sentence, I have verified that when the RMC sentence (multiplexed with the DBT sentence which you had provided) is received via the T122's NMEA 0183 IN2 port, then the TackTick display repeats the received GPS data and I also verified that the T122's NMEA 0183 output port transmits NMEA 0183 sentences containing GPS data.
