[. . . ] The first screen will prompt you for the interface you would like to use. COM1 or COM2 or IEEE can be selected by pressing <1>, <2> or <3> respectively. For IEEE communications, the TERMINAL program assumes that an IEEE interface card PC-488 from CAPITAL EQUIPMENT CORPORATION (CEC: 617-273-1818) has been installed in the host computer. The terminal program will not work with any other IEEE-488 interface card. Page 1 ©2000 DH Instruments, Inc. PPC Communication Software User's Manual After the interface selection has been made, the terminal program will search for the PPC. If one of the serial interfaces is selected as the communication port, the terminal program will search for the PPC at different baud rates from 9 600 to 300. If the IEEE interface is selected, the program will first ensure that an IEEE card is installed in the computer, then search all available addresses from 1 to 30 attempting to establish communications with the PPC. Once the program locates the PPC, the remote light on the PPC will come ON and the screen should fill with the returned data. The terminal program will now be monitoring the current pressure in the PPC. If communication with the PPC is not established, check your RS232 cable pin-outs. If your PPC has an IEEE interface, be sure that the interface selector switch on the back of the PPC is set to the proper position. 1. 2. 1 OPERATION The top part of the screen contains the most common parameters used for pressure generation. These parameters can be easily changed by pressing the appropriate highlighted key and entering the required data. The actual data is the only parameter that has to be entered. The terminal program will send out the corresponding command in the proper format. When setting any of these parameters, a message will be displayed in the current pressure window to indicate what is being changed. Table 1 lists these parameters along with the related KEY PRESS and the actual command that it corresponds to.

The middle part of the screen is used for pressure monitoring and pressure generation. 1. 2. 2 PRESSURE GENERATION 1. 2. 2. 1 GENERATION MODE The GENERATION MODE can be set by simply pressing [G]. [. . . ] After a ready indicator is received, then this delay will be executed before the next pressure will be generated. If a delay of 0 (zero) is entered, then the next pressure generation will not begin until the [C] key has been pressed. This allows you to stay at a pressure for as long as you like and continue when you are ready. · · · · Once a pressure array has been set up, it can be executed by pressing [F]. 1. 2. 3 REMOTE COMMAND The remote command can be used to send any command to the PPC. When using the remote command < -- REMOTE COMMAND -- > will be displayed in the current pressure window. [. . . ]
