A Virtual repository of information on the,
Husky Hunter Series of Computers.
The 'Null Modem' Cable and the Hunter 16 Com Port Pinout
It is this primary Serial connector, located on the right hand side, which is used to connect the Husky to a PC and
transfer both software and the collected data to and from the host machine.
I have used a standard ' Null Modem 'cable to connect to both the Husky 2 and the 16.
The utility to use on the PC is called 'HCOM' and connects a variety of Husky's to the PC, the software is available from
the usergroup file area at ( http://groups.yahoo.com/group/huskycomputers )
Please visit the user group as they are a helpful group of dedicated users and I
for one am only able to utilise my newer Husky due to thier considerable help, after my original Hunter 2 died
( So they may be rugged but not indestrucable ! ( Yet ).
Here is a diagram :-
