Probe Interface PCB(Connector Board)
Logiq Uno Connector board is designed to support 64, 96 and 128-element probes. Depending on the
scan line number, 48-specific elements out of 64/96/128 elements are connected to the respective TxRx
sections.
CONN board includes 128-HV-switches which acts as acts as Multiplexer/De-Multiplexer to steer 48
transceiver signal lines from TxRx board to the selected 48 - transducer elements of the probe. HV
Switches can handle a maximum of 200V PP transmit pulses.
Logiq-Uno CONN board supports two probe ports with only one probe is active at a time. To switch
between the two probes a bank of 128 electromagnetic relays are used.
CONN board includes a FPGA to generate the HV switch programming data that will steer the TxRx
signals to the correct probe elements. FPGA has following read/write registers to interface with the
master controller board (MST):
Read registers from connector board….
1.) creg0 at address X03H is temp(7:0)
2.) creg1 at address x04H is temp(15:8)
3.) creg2 at address x05 is connector board revision number
4.) creg3 at address x06 is probe port status…..Its 11111& Probe2 status & Probe1 status & Probe0
status
5.) creg4 at address 0x07 is probe code for port0
6.) creg5 at address 0x08 is probe code for port1
Write registers to connector board….
1.) reg1 at address 0x01 is PRMCHG & MUXPRB & X & CONNUM(1:0) & RegFreeze(2:0)
2.) reg2 at address 0x02 is start element
