ASI Out — BNC 5 or BNC 6
BNC 5
on the MDL-R20 (
BNC 6
on the MDL-R10) is the output of the 310-to-ASI converter.
GPI/O Outputs
The GPI/O outputs are provided on a nine-pin connector with eight logic outputs (3.3V) and one ground
connection. (
Table 1.2 ) These GPI/O outputs carry the ASI-310’s GPI/O outputs that can be used to control
external equipment. Note that the GPI/O outputs are logic signals: the high level is 3.3V and the low level is 0V.
Each output is suitable for driving a logic circuit or LED through a short cable. If you need to drive high-current or
high-voltage loads, or loads that are referenced to a different ground that the ASI-310 card, use an external relay
circuit between the GPI/O pin(s) and the load.
Refer to Figure 1.5 for pinouts on the MDL-R10 and Figure 1.6 for pinouts on the MDL-R20 .
