To quickly get the UT200SpW4RTR-EVB up and running the following steps should be followed
1. Connect headers J57, J59, and J58
a. This will enable external power supplies to be used
b. Ensure that headers J64 and J65 are not connected.
2. Connect BNC connectors to J54 3.3V, J56 2.5V , and J55 5.0V
3. Determine which SpW interface you would like to use
a. LVDS – Connect Pin 2 J70 to VDD
b. LVCMOS – Connect Pin 2 J70 to VSS
4. Are you going to use the HOST port?
a. Yes – Set Pin 1 J70 to VSS and Pin 3 J70 to VSS
b. No – Set Pin 1 J70 to VDD and Pin 3 J70 to VDD
5. Determine the data rate you would like to use to clock the SpaceWire ports
a. Use the UT7R2XLR816 Clock Network Manager Software GUI to determine the configuration of the signals
on the 43 pin connector
b. Configure the UT7R2XLR816 using the corresponding pin on the 43 pin connector such that you will get the
proper TXCLK_IN_#, HOST_CLK, and V2_CLK
c. Using J73 set the Initialization Divide Register TX_DIV[4:0] such that one of the TXCLK_IN rates
initializes the UT200SpW4RTR at 10Mbps ±1Mbps
d. Hook up your instruments to the SpaceWire ports
e. Power on the board
