[02-MAY-22] The Direct Fiber Positioning System (DFPS) Backplane (A3044) consists of a long, rigid circuit board into which we plug multiple service boards, such as the DFPS Base and Service Board (A3043).
The service boards in turn receive the controllers for the positioners in the cell. The base board and service board are one assembly connected by flex cables. The backplane proviodes power and logic control signals to all its cells.
The Test Stand one backplane will provide three connectors for service boards, as well as connectors that deliver ±250 V to the system for electrode drive, 2.4 V and 1.2 V for logic and conversion, and SDO and SDI for communication with the fiber controllers.
The following versions of the DFPS Backplane (A3044) are defined.
|A||A3043||3 × 1 with 20-mm spacing||Backplane for 4×4 cells.|
[18-JUL-22] We have the bridge plate mounted on our Test Stand One, ready for the backplane.
