TEWS TECHNOLOGY – TPMC866-11R

Technical Parameters:

Form Factor: Standard PCI Mezzanine Card (PMC) compliant with IEEE 1386.1 standard.

Channel Configuration: 4 independent, fully software-programmable asynchronous serial channels.

Interface Standards: Each channel is individually configurable for RS-232, RS-422, or RS-485 physical signal layers.

Baud Rate Capacity: Supports high-speed data transmission rates up to 5.5 Mbps for RS-422/485 modes and up to 460.8 kbps for RS-232 mode.

FIFO Buffers: Equipped with a high-capacity 64-byte transmit/receive FIFO buffer per channel to optimize CPU overhead and prevent data loss during heavy bursts.

Isolation Barrier: Features 1SR functional galvanic isolation (non-isolated version available depending on sub-ordering codes, but standard “R” suffix typically designates specific ruggedized front/rear I/O wiring paths).

Physical I/O Architecture: Configured for Rear I/O routing via the P14 backplane connector, keeping front panel cabling clear in dense embedded racks.

Logic Compatibility: 32-bit PCI target interface compliant with PCI Local Bus Specification Revision 2.2, supporting both 3.3V and 5V signaling environments.

Thermal Operational Range: Extended industrial operating temperature range certified from -40°C to +85°C.

Industrial Sectors:

Aerospace and Defense Systems, Transportation and Rail Automation, Telecommunications Infrastructure, Embedded Industrial Computing, and Marine/Naval Controls.

Application Scenarios:

1. Ruggedized Embedded Computing Frameworks: Installed onto VME, VPX, or CompactPCI carrier boards to expand multi-channel serial capability inside military-grade mission computers and rugged avionics bays.

2. Real-Time Telemetry and Data Logging: Deployed within aerospace flight testing systems or ground stations to aggregate continuous stream data from legacy GPS units, telemetry arrays, and radar sub-components.

3. Subsurface and Maritime Communications: Integrated into deep-sea remotely operated vehicles (ROVs) or surface vessel navigation racks to manage long-distance RS-485 sonar links and physical sensor paths.

4. Industrial Automation Central Gateways: Used in high-reliability transit control cabins to bridge legacy point-to-point serial communication buses over to modern backplane system architectures without data lag.
