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.
