AP513: Quad Isolated Serial RS232 Communication Module

These modules provide four isolated serial communication ports from a single AP carrier slot for a high-density solution. Software-configuration helps you quickly set baud rates, character-sizes, stop bits, and parity. RTS/CTS handshake support for modem control is also included.

For more efficient data processing, each serial port is equipped with 256-character FIFO buffers on the transmit and receive lines. The large buffers minimize CPU interaction for improved system performance The data ports generate individually controlled transmit, receive, line status, data set, and flow control interrupts. All interrupts can be read from a single register.

The AcroPack® product line updates our popular Industry Pack I/O modules with a PCIe interface format. This tech-refresh design offers a compact size, low-cost I/O, the same functionality of the existing Industry Pack modules and a rugged form factor.

AcroPack modules are only 30mm wide and 70mm long. This is just 19.05mm longer than a full length mini PCIe card but the same width. AcroPacks also use standard mPCIe board hold down standoffs and screw keep out areas.

A down facing 100 pin Samtec connector mates with the carrier card. Fifty of these pins are available for field I/O signals. Pin spacing and signal assignments will allow for 100V of port to port isolation.

PCI Express Base Specification

Conforms to revision 2.0
Lanes: 1 lane in each direction.
Bus Speed: 2.5 Gbps (Generation 1).
Memory: 4k space required. 1 base address register.

Environmental

Operating temperature: -40 to 85°C with minimum airflow of 200LFM. (Conduction-cooled applications require heatsink kit, Model AP-CC-01).

Power
3.3V (±5%) 130mA idle, 200mA typical.
Internal Isolated Power
Isolated power is created onboard using LTM2882 Isolated Transceiver Power, so isolated power does not need to be supplied externally.
