Installation of the electronic pipeline for the tiltmeter in NEB

During Tuesday morning (May 14) we installed all the electronic pipeline for the data acquisition of the tiltmeter in NEB. We verified the functioning of the data acquisition sending a signal to the DAC and injecting it in a ADC at the front end panel near the tiltmeter. We also installed an Ethernet RS232 bridge near the tiltmeter to control by remote two DC motors.

Actually what we installed is a standalone UDSPT board (see attached photo). Analog i/o was connected to tiltmeter front-end electronic. Optical link was connected to mux/demux sn24, ch. 3. Board power supply was connected to Suspension Control System PDU (Port#3). Dictionary data prefix is set to ENV_NE. Tolm packet routing is set to 0xf94c000. We check proper connection of analog i/o. Connection with timing distribution was validated while DAQ connection test is pending (we are now sending 6 signals).
