-12: Earth Ground

Communications Interface

This line connects to the gaussmeter
chassis which is connected to the center

terminal of the line cord power receptacle.
The use of this pin is optional and is normally
tied to the shield of a shielded multi-

conductor cable to minimize RFI/EMI
radiation problems. DO NOT CONNECT
THIS EARTH GROUND TO THE COMMON

RETURN LINES (Pins -18 thru 24)!

Pin-17: Remote Enable (REN) Asserted by the system controller to tell the

systems receiving data that they can actually

use the data, and that their front panel
controls are locked out.

Pin-18.19. 20. 21. 22. 23. 24  T h e s e  are the common return lines for all
Ground (GND1

r

 signals 

except 

earth ground (Pin-12).

Each device on the system bus must be assigned a unique address ranging

from 00 to 31 decimal. All devices can have one primary and another
secondary address. Many devices, including the SERIES-9900, use the
same address for both. The address is assigned using the
COMMUNICATIONS FORMAT menu. See Section IV. Also, see Section V-E
for detailed programming information.

VI-D  I E E E -488 ELECTRICAL INTERFACE

The interface between each device is straightforward. Each interface line
attaches to the same line on the next device (ATN to ATN, DIO1 to DIO1, etc.)
