4.2 Interface to PC
The RTC
®
5’s PCI connector is the interface to the PC.
The RTC
®
5 can be installed into any IBM-compatible
personal computer with a PCI bus interface and at
least one free PCI slot.
4.2.1 Master/Slave Synchronization
If multiple synchronously-clocked RTC
®
5 boards are
to be used in a PC, then the RTC
®
5 boards must first
be connected pairwise with each other via the
MASTER and SLAVE connectors and then installed in
adjacent PCI slots. Always connect a board’s MASTER
connector to the SLAVE connector of another board.
Suitable connection cables are available from
SCANLAB.

page 84 and "Starting and Stopping Lists via External
Control Signals and Master/Slave Synchronization",
page 209.

bus. Accordingly, you must disable standby or
sleep modes of the operating system. Also see
the note on page 27.
