Output Connections with the ER-16
The VXI-DIO-128 can power a maximum of 16 ER channels. The
VXI-DIO-128 su5 V to these ER channels via the +5 V connectors
(J5 or J6). Set the power source switch for the ER-16 that is connected to
J5 or J6 to
external
. Also, set the power source switches for the ER-16
boards connected to ports 10–11 and 12–15 to
external,
and externally
supply them with +5 V. The ER-16 connected to ports 14–15 needs to have
its power source switch set to
internal
. This board is su5 V through
the NB7 cable.

Output Connections with the 32 Channel SSR Backplane
* An external power supply is needed if more than 1 A of current is required
to power the SSR backplanes. The current requirements for the SSR
modules are as follows: SSR-OAC-5: 18 mA, SSR-OAC-5A: 19 mA, and
SSR-ODC-5: 16 mA.
