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. |
