1.3 AcroPack Information
–
All Models
The AcroPack IO modules are based on the PCI Express Mini Card
Electromechanical specification and are 70mm in length with an additional
100 pin field I/O connector.
The AcroPack is 19.05mm longer than the full length mini PCIe card at
50.95mm. It has the same mPCIe board width of 30mm and uses the same
mPCIe standard board hold down standoff and screw keep out areas.
The AP512 uses the 16550-compatible Exar 17v354 UART and contains four
isolated RS-422/485 serial communication ports that provide EIA-TIA-422B
or full duplex EIA-485 line support. Each port has 250V of isolation from
digital circuitry and 100V of isolation from the other 3 ports.
There are no termination or biasing resistors installed by default. For
internally terminated ports please consult the factory. There is no support
for internal biasing resistors.

Note 1
: For all models
listed - all standoffs and screws required for an air cooled
application are provided with the carrier.
Note 2
:
A conduction cooled application will require purchase of AcroPack

(Conduction Cool Kit).
1.3.2 Key Features
•
High Density
–
Provides 4 serial ports on each module.
•
Isolation
–
Each port has 250V of isolation from digital circuitry and
100V of isolation from the other 3 ports.
•
Internal Isolated Power
–
Isolated power is created onboard using
Analog Devices ADM2882E Full Duplex RS-485 transceivers, so
isolated power does not need to be supplied externally.
