   | Note (1):For single pulse width measurement, connect the   |
   | input signal to pins 10 and 11 of header H1.               |
   |                                                            |
   | Note (2):For pulse width measurement between two pulses,   |
   | connect one signal to pin 10 of header H1 and the other    |
   | signal to pin 11 of header H1.                             |

   |               MISCELLANEOUS TECHNICAL NOTES                |
   |------------------------------------------------------------|
   | The CTM-10/CTM-11 is a modular daughter-card designed to   |
   | work with the Quatech PXB-721 or MXI-241.                  |
   |                                                            |
   | Header H1 signal connections are as follows: pins 1 - 3 =  |
   | CLK 0 - 2, respectively, pins 4 - 6 = Pulse Output 0 - 2,  |
   | respectively, pins 7 - 9 = External Input 0 - 2,           |
   | respectively, pins 10 and 11 = Pulse Input 1 and 2,        |
   | respectively. Pins 14 - 26 are connected to ground and     |
   | pins 12 and 13 are unused.                                 |
   |                                                            |
   | The purpose of all other jumpers on this card are not      |
   | identified in manufacturer's documentation.                |
