Hello
in the last few months i have replaced the back up "gold" cap in the trimble and in the down hole tool.
and also replaced the IR transmit/recieve device in battery assembly
this has been intermittent with operation for some time.
some times i get Msg190 (no data from tool)
sometimes I get MSG111 (wrong date/time format) eg day 1 of month 0 of year 2000
this unit uses IR compaired to modern units use BT
when this says no data ( what is because it is already transmitting streem.)
the instruction book is basic or useless
