112 SBC329 3U VPX Single Board Computer
Publication No. SBC329-HRM/1
Signal
Description
COMn_TXD/TXD_A
Serial COM port n (n = 1 or 2) Transmit Data signal (RS232 mode) or Transmit Data A signal (RS422 mode)
COMn_RXD/RXD_A
Serial COM port n (n = 1 or 2) Receive Data signal (RS232 mode) or Receive Data A signal (RS422 mode)
MSKABLE_RESET~
OpenVPX Maskable Reset signal. Pulling this input low for a minimum of 10 ms will cause a hard reset to the SBC329
unless it is masked (unmasked by default). This pin can also be driven by the SBC329 via the FPGA
XMC_xxx
XMC I/O connections from the
USB_P2_PWRA/B
USB3.0 port 2 power
USB3_P2_RXP/N,
USB3_P2_TXP/N
USB3.0 port 2 Receive and Transmit differential pairs
BITFAIL~
Open drain BIT Fail drive for system level BIT Fail
COM2_RTS~/TXD_B
