Different components of a TSX PCI 57 processor module

Illustration

This table describes the components of a processor module:

Number	Function
1	RUN, TER, BAT, I/O and FIP indicator LEDs (the FIP LED is only present on the TSX PCI 57 354 model).
2	Slot for a type 1 PCMCIA memory extension card.
3	Micro-switches for coding the rack address on the X Bus.
4	Micro-switches for coding the module’s position on the rack.
5	Slot for a PCMCIA type 3 communication card.
6	Female 9-pin SUB-D connector used to remote the X Bus to an extendable rack.
7	Terminal port (TER connector (8-pin mini-DIN)): this is used to connect an FTX type or PC compatible terminal, or to connect the PLC to the Uni-Telway bus through the TSX P ACC 01 insulation unit. This connector is used to supply 5V to the peripheral which is linked to it (limited by the available current provided by the PC's power supply).
8	Recessed RESET button which when pressed causes a cold startup. Processor working normally: cold startup in STOP or RUN mode, according to the procedure defined in the configuration, Processor error: forced startup in STOP mode. The RESET button must be pressed using a non-conductive object.
9	ERR LED.
10	Male 9-pin SUB-D connector for linking up to a master Fipio bus. This connector is only present on the TSX PCI 57 354 processor.
11	32-bit PCI connector, used for linking up to the host PC.
12	Slot accommodating a battery for backing up the processor’s internal RAM memory.

NOTE: The TER terminal port offers master Uni-Telway communication mode by default, and can be configured for slave Uni-Telway or ASCII character mode.
