Configuring the HP E1399A

This Chapter contains a detailed hardware description of the breadboard
module and discusses the backplane interface circuitry. It also shows a
sample application to control 16 relays on the module.
WARNINGS, CAUTIONS, and guidelines to reduce the risk of static
discharge damage to the HP E1399A follow.
SHOCK HAZARD. Only qualified, service-trained personnel who
are aware of the hazards involved should install, remove, or
configure any module. Before removing any installed module,
turn off all power to the mainframe and to all external devices
connected to the mainframe or to any of the modules.
For electrical shock protection, ensure that the module face
plate is securely tightened against the mainframe.
Since the inputs to the HP 1399A Breadboard Module are
through a 96 pin connector and a terminal card assembly, limit
voltage to 250Vdc/250Vrms.
STATIC SENSITIVITY. The backplane interface circuitry
described in this Chapter uses static-sensitive CMOS
integrated circuit devices. If you implement the circuitry
described herein, you must use clean-handling and anti-static
techniques when handling the module to protect the sensitive
components from damage due to electro-static discharge (ESD).
