   |               MISCELLANEOUS TECHNICAL NOTES                |
   |------------------------------------------------------------|
   |   The DM8-10 is a modular daughter-card designed to work   |
   |            with the Quatech PXB-721 or MXI-241.            |
   |                                                            |
   | Channel 0 through channel 6 output is taken from pins 1 to |
   |  7, respectively, of header H1 while channel 7 output is   |
   | taken from pin 11 of header H1, 2, or 3 of header H1. The  |
   |        rest of the pins of header H1 are grounded.         |
