   |               MISCELLANEOUS TECHNICAL NOTES                |
   |------------------------------------------------------------|
   | Note: Terminating resistors are usually only needed if the |
   | card is installed in systems using high baud rates. If     |
   | terminating resistors are required, insert them into the   |
   | listed locations. Size and type of resistor are            |
   | unidentified.                                              |
