Printers
Due to the rapid changes in the computer industry the availability of any particular printer may
change. Due to this fact, please contact NDT Systems for current printer recommendations
Figure 5.2.1 Communications Connection
The NDT systems part number for this cable is TE232. One was included with the instrument when
shipped. Please use this part number when ordering replacement cables.
NOTE:
IBM compatible computers may incorporate several types of RS-232 connection schemes. These
ports are commonly referred to as COM1 thru COM4. We would suggest connection to COM1 if
possible but COM2 will also work. Avoid the use of COM3 & 4 if possible. Frequently, COM1 & COM2
are 9 Pin Sub-D’s and sometimes COM1 is a 9 Pin and COM2 is a 25 Pin. Try to use the port with the
same connector as the TE232 cable. If the connector configuration is not compatible you may obtain
an adaptor from any computer supply house such as Radio Shack, Staples etc. You may also contact
NDT Systems for assistance & the appropriate adaptor.
