Q. What do the switches on the SMT105 do?
The switch SW2 has four switches.
SW2 switch 1:
Reset Select
On: Hardware Off: Software
SW2 switch 2:
Select which “bit” file in the flash the FPGA is configured from
On: Default (* position 0) Off: User (* position 1)
* Bitstream position store in flash, set with the SMT6002
SW2 switch 3:
On: Erase / Program Flash Off: Direct Load FPGA (Via USB)
SW2 switch 4:
Link Mode
On: PCI / PCIe Off: USB
SMT105 SW3:
ON/OFF
1: BYTE_MODE
2: nSPROG
3: not used
4: not used
What is this bit of the SMT105?
If you have an SMT105, and are wondering what or where a certain part is, you can use the helpful interactive images on the pci104.biz website.
The images can be found on this page
How to I set the I/O voltage for the SLB on the SMT105?
To set the I/O voltage for the SLB on the SMT105 you need to fit jumpers on J3 and J9 (One is for the SLB data and the other is for Control).
Fit the jumpers next to the FPGA for 2.5V, and away from the FPGA (next to the idents) for 3.3V
What is the pin out of the external power connector (PWREXT1)?
The external Power connector (PWREXT1) on the FPGA side of the SMT105 has the following pin out:
Pin 1: +12V (nearest the Crystal Oscillators X2 and X3)
Pin 2: +5V
Pin 3: +3.3V
Pin 4: GROUND
Pin 5: -12V
The mating connector we use at Sundance is made from:
ERNI 254827 (Housing)
ERNI 284071 (Crimps)
More information can be found in this PDF from ERNI. PDF information sheet
If needed these parts can be bulk ordered from www.jacarem.co.uk.
