Some embodiments of the invention provide configurable via programmable gate array with several configurable circuits arranged in a configurable circuit arrangement. The side rail mounting assembly includes a rail-receiving member defining a passageway configured to releasably receive the side rail and a support rod fixedly engaged to and extending from the rail-receiving member. The transmission line may, for example, be a 50 ohm RF line for transmitting RF energy. With the structure thus arranged, the ink jet recording head is capable of optimizing the discharge characteristics of recording liquid and the supply characteristics thereof, as well as the positioning precision of a recording element base plate to a supporting member. Further, the system and method includes providing control by reducing the effects of hysteresis in solenoid actuated devices by providing a non-operational signal to the solenoid actuated device.
