The **CPCI-R6000-L** is a Rear Transition Module (RTM) designed for use in CompactPCI systems, typically paired with specific 6U CPU boards (often from manufacturers like ADLINK or similar industrial computing brands). Its primary function is to route I/O signals from the main CPU board through the backplane to the rear of the chassis, allowing for easier cabling and maintenance. --- ### 1. Key Electronic Components and Architecture | Component Type | Description | | :--- | :--- | | **Form Factor** | 6U CompactPCI Rear Transition Module (80mm depth). | | **Connectivity** | High-density J3/J4/J5 connectors to interface with the front-side CPU board. | | **USB Controllers** | Onboard circuitry to support multiple USB 2.0 ports. | | **Ethernet PHY/Magnetics** | Supports Gigabit Ethernet passthrough (usually 10/100/1000 Mbps). | | **Serial Controllers** | RS-232/422/485 transceivers for COM port communication. | | **Storage Interfaces** | Onboard SATA connectors for HDD/SSD integration. | --- ### 2. Interface Breakdown The "L" variant often signifies a specific configuration of ports. Standard electronic interfaces found on the R6000 series include: * **Networking:** Dual RJ-45 ports for Gigabit Ethernet. * **Video:** VGA or DVI-D output (depending on the specific revision) for display interfacing. * **Serial Ports:** D-Sub 9-pin connectors for legacy industrial device control. * **USB:** Multiple Type-A USB 2.0 ports for peripherals. * **Storage:** Internal SATA headers to allow a disk drive to be mounted within the RTM slot area. --- ### 3. Electrical Specifications * **Voltage Requirements:** Primarily draws +5V and +3.3V from the CompactPCI backplane. * **Hot Swap Support:** Most versions support "Hot Swap" capabilities, allowing the module to be replaced without powering down the entire system (requires software support). * **Signal Integrity:** Uses multi-layer PCB routing to ensure high-speed signal integrity for SATA and Ethernet lines. --- ### 4. Compatibility Note The CPCI-R6000-L is **not** a standalone computer. It acts as an extension of the front-side processor board (such as the CPCI-6841 or CPCI-6930). The electronic layout is strictly mapped to the pinout of the specific CPU board it was designed for.
