Cabling the PTM
This section provides the instructions for connecting a QSPI cable to a multi-unit
library system. This section also includes a QSPI bus description.
QSPI bus
The QSPI bus is a full-duplex synchronous serial interface for communicating
with peripherals and other micro-controller units. The QSPI bus is a standard
Motorola bus that ESL9000 multi-unit library systems use as a custom control
language to communicate between master and slave libraries.
Note: The QSPI bus must be terminated at both ends for proper operation.
Cabling instructions
To cable the libraries:
1. Using a 5/32-inch hex key wrench, open the rear access door of each library
being connected.
