346 Installation and Mainframe Configuration[ RS232C PRE-INSTALLATION CHECKLIST 1Are the 3497A character length, parity bit, speed of operation andnumber of stop bits compatible with your controller?Will ENQIACK or DC1 handshake be used? ENQIACK is implemented bysoftware (see Chapter 41, while DC1 is set by placing the DC1 Handshakeswitch (S1, position #4) to the "1" position (see MAINFRAMECONFIGURATION).Will MODEMs be used? If used, MODEMs must be asynchronous andfull-duplex (preferably one of the MODEMs listed earlier in this chapter).Is S2 set for RS232? (see MAINFRAME CONFIGURATION).If your controller has an ECHO function, is this turned OFF? Does thecontroller accept CR (only) as a terminator?Connecting the 3497AControllerWhen the 3497A has been set for desired operation, the next step is to connectit to your controller, either by direct connection or via MODEMS.Supplied with each 3497A Option 232 is a US MODEM cable 13222N (-hp- partnumber 13222-60001) for interface between the 3497A and your controller orMODEM. This cable consists of a 50-pin male connector to connect to the 3497Aand a standard 25-pin RS233C male connector for connection to a MODEM or toa controller. Figure 64 shows the pin definitions for the 13222N cable.Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
