Stainless Steel Female DB9 connector. 

 

Fixed  RS232  9600  baud,  8  data  bits,  2  stop  bits,  no  flow  control. 
The data logger can receive at this data rate without flow control. 

 

After  asserting  the  DTR  signal,  a  minimum  of  5  seconds  must 
elapses before the data logger can respond. 

 

In order to minimize power consumption the TXD output is turned 
off 30 seconds after the last byte has been sent. When this output 
is off, it will be at or near ground unless an external device forces it 
to a different level. Software and hardware communicating with the 
data logger must be able to deal with the possibility of a transient 
when the transmitter is turned on. The data logger will not send the 
first  byte  until  the  driver  has  been  active  for  at  least  one  full 
character time. The receiver is always active. 

MATING CONNECTOR: 

 

Standard DB-9 male connector  

HDL1-G5 GPS ANTENNA CONNECTOR 

  

Standard SMA female connector 

 

SMA connector feeds the GPS signal to the internal GPS module.  

HDL1-G5 GOES ANTENNA CONNECTOR 

  

Standard Type N female connector 

 

N connector feeds the RF transmission to the GOES antenna
