Fig. 2 shows recommended "full-handshake" RS-232-C cabling between the PC-

HSICA card and a Daytronic instrument's 25-pin COMPUTER INTERFACE PORT

(e.g., for a System 10 mainframe). Fig. 3 shows recommended "full-handshake"

cabling between the PC-HSICA and a Daytronic 9-pin COMPUTER INTERFACE

PORT (e.g., for a 3500 or 4000 Series instrument). Daytronic offers a standard 10-

foot cable (No. 52203) for connecting a System 10 to the PC-HSICA.

FOR FULL DETAILS CONCERNING CABLE CONNECTIONS BETWEEN THE PC-

HSICA'S RS-232-C INTERFACE CONNECTOR AND THE COMPUTER INTER-

FACE PORT OF A SPECIFIC DAYTRONIC INSTRUMENT, SEE THE DISCUSSION

OF "FULL-HANDSHAKE" SERIAL CABLING IN THE RELEVANT SECTION OF THAT

INSTRUMENT'S INSTRUCTION MANUAL. YOU SHOULD ALSO STUDY THE LIT-

ERATURE ACCOMPANYING YOUR SOFTWARE SERIAL DRIVER, TO DETERMINE

THE PRECISE HANDSHAKE THAT MAY BE CALLED FOR. IF YOU ARE IN ANY

DOUBT AS TO THE SUITABILITY OF A PARTICULAR CABLE CONFIGURATION

FOR YOUR APPLICATION, FEEL FREE TO CONTACT THE DAYTRONIC SERVICE

DEPARTMENT FOR ASSISTANCE.

Note that it is NOT necessary to tie pins 5 and 6 at the PC-HSICA end of the cable

(this is required only for direct connection between the instrument and an IBM or

IBM-compatible serial port). Note too that a separate power supply is not

required for the Model 10E422 RS-232-C to RS-422 Converter when it connects

directly to a PC-HSICA card.
