Table 3-6: Card Number Configuration Settings
Default card number is 0.
3.7.2 SSI Timebase
As an output, the SSI_TIMEBASE signal outputs the onboard
10MHz through ACL-eSSI-2/ACLeSSI-3/ACL-eSSI-4 cables. As
an input, the PCIe-9852 accepts the SSI_TIMEBASE signal to be
the source of timebase.
3.7.3 SSI_TRIG
As an output, the SSI_TRIG signal reflects the trigger event signal
in an acquisition sequence. As an input, the PCIe-9852 accepts
the SSI_TRIG signal to be the trigger event source. The signal is
configured in the rising edge-detection mode.
3.7.4 SSI__pre_data_rdy
If one SSI slave is set to mid-trig or pre-trig mode, the SSI master
should also be in mid-trig or pre-trig mode. SSI slaves in mid-trig
or pre-trig mode should send pre_data_rdy to SSI master through
SSI[0], SSI[1], SSI[5] or SSI[6].
A SSI master sends SSI_trig to other SSI slaves. If set to pre-trig
or mid-trig mode, SI_pre_data_rdy is received from other SSI
slaves. SSI slaves should be set to mid-trig or pre-trig mode to
send SSI_pre_data_rdy signal to the SSI master. Different SSI
slaves should not use the same SSI pins.
