The CT15 is a 6U VMEbus transition module for use in combination with MEN's A602 single-board computer.
It is plugged onto the VMEbus backplane system slot from the rear side and leads the rear-panel serial I/O signals to standard connectors.
The signals are one RS232 UART, various signals from the two PMC slots (standard rear I/O from PMC1, AFDX from PMC2), the necessary signals for inter-board communication when connecting a second A602 (BMCX, DEX (6x UART), ACTIVE_THIS/OTHER) and various debug signals (/COM_FAIL, DI_PSU_STATUS, N_TEST and the AUX_IO signals).
It also offers a reset button, a boot switch, five LEDs for the N_TEST signals from the A602's North FPGA and five rotary switches allowing the /COM_FAIL, DIT_XTRL, DIT_SW_OVER, DIT_WDCTRL and DI_PSU_STATUS signals to be pulled low with an option to connect /COM_FAIL to +3.3V.
The board is designed for an operating temperature from -40 to +85°C with qualified components.
