CompactPCI®   Wireless Technologies Carrier Board

  • CP4-SCAT

The CP4-SCAT is a 3U/4HP CompactPCI® peripheral board, intended for industrial and railway wireless communication.
The CP4-SCAT is provided with a PCI Express® Mini Card socket. Based on both, the PCI Express® and USB standards, PCI Express® Mini Cards became very popular for wireless industrial applications, such as WiFi (WLAN), GSM, LTE, WiMAX, GPS.

The CP4-SCAT is equipped in addition with a socket for the MC55i TRM-3a GSM-R (Railway Radio) module. GSM-R features include EIRENE and ASCI.
Up to 3 antenna connectors (SMA/RP style) in the CP4-SCAT front panel allow for MIMO (RF multiple-input multiple-output) Mini Card employment. Typically, wireless Mini Cards provide U.FL style antenna receptacles. A double ended U.FL plug coaxial cable assembly will be required for each Mini Card receptacle as interconnection to its associated front panel SMA connector. Another SMA connector is provided for the optional GSM-R module.
Furthermore, the CP4-SCAT front panel is populated with three USB 2.0 connectors for attachment of external devices.
The main building blocks of the CP4-SCAT are the PCI Express Mini Card socket (based on USB and PCI Express I/O), and the GSM-R modem (relies on a UART port).

A PCI to PCI Express® bridge on the CP4-SCAT converts the parallel PCI signals of the CompactPCI® backplane to serial PCI Express® data. Since the bridge provides only a single PCI Express® lane, it is fed to the upstream port of a multi-port PCIe switch for replication. The so called SWIDGE, a combined PCI Express® packet switch and PCIe to USB bridge, has two PCIe downstream ports. One lane is used for the PCI Express Mini Card socket, the other for the PCIe based UART (Universal Asynchronous Receiver/Transceiver), which is the gateway to the MC55i/TRM-3a GSM-R module.

The SWIDGE component contains not only a PCIe switch, but also a PCIe to USB bridge. One of the channels of the quad-port USB 2.0 controller is wired to the PCIe Mini Card socket, and the remaining to the USB front panel receptacles.
PCI Express® Mini Cards are controlled either via their USB interface, or by a single lane PCIe link. Both data paths are derived from the SWIDGE component as described above, and allow for application of either type Mini Card.

The optional GSM-R modem module is controlled by AT commands via its serial interface. This is the reason why the CP4-SCAT is also equipped with a PCI Express® based UART. If no GSM-R radio is required, the UART can be either omitted, or optionally used in combination with the EKF CU7 or CU8 PHY modules for RS-232 or RS-485 I/O.

The CP4-SCAT has been designed for +5V only operation. As an option, an on-board switching regulator from +5V to +3.3V is available, which can be used to feed back +3.3V/10A to the CompactPCI® backplane in systems with a single +5V power supply.
