14.4 PC Card Slot / SRAM
A PC card slot which can be accessed with the housing closed is available on the interface
board. Type I, II or III cards can be used in this slot. The slot is compatible with PCMCIA Release
2.0 and JEIDA V4.1 standards and is operated as PC card socket 1. We recommend use of
memory cards with Tuple (also known as CIS).
The I/O address is permanently set. The assignment of an interrupt is made - if necessary
(depending on card) - using Plug & Play (see section "Interrupt Assignments").
A 256 KB SRAM integrated in the interface board can be accessed via PC card slot 2. To the
user, this memory looks like an inserted PC Card.
Buffering takes place with a lithium battery on the interface board (3 V, 950 m Ah). The lifespan
of this battery is at least 1.5 years, but typically 4 years (at 50°C and 256 KB SRAM).
It is possible to protect the internal SRAM from being written to unintentionally by using a write
protect switch. This switch is accessible from the outside through a small opening. If the switch
is pointing in the direction of the PC card slot, then write protection is activated.
Operating a compatible PC card is not possible without a corresponding driver. These
are available from B&R (model number 5S0002.01-020).
