   |               MISCELLANEOUS TECHNICAL NOTES                |
   |------------------------------------------------------------|
   |  The DM12-10 is a modular daughter-card designed to work   |
   |            with the Quatech PXB-721 or MXI-241.            |
   |                                                            |
   |  Channel 0 output is taken from pins 1, 2, or 3 of header  |
   |   H1. Channel 1 output is taken from pins 5, 6, or 7 of    |
   | header H1. The rest of the pins of header H1 are grounded. |
