Interfaces The plotters operate with a variety of computer systems through either the serial, RSĆ232ĆC port or the parallel, BiĆTronics, extendedĆcapability port (ECP). An autoswitching feature enables the plotter to detect from which interface it is receiving data, so you can send data through either interface without having to change the plotter settings. (More on interfaces ' chapter 5, w Input/Output Interfaces.) Network Connections You can connect the plotters to a network through an optional HP JetDirect EX or HP JetDirect EX Plus3 external print server. The range of network operating systems that are supported are as follows: Local Area Network Network Operating System Computer Operating System Ethernet Novell Netware LAN Manager TCP/IP TCP/IP EtherTalk DOS, Windows DOS, Windows HP-UX, Sun OS, Solaris IBM AIX Macintosh, Apple Products Token Ring Novell Netware LAN Manager TCP/IP DOS, Windows DOS, Windows HP-UX, Sun OS, Solaris, IBM AIX The print server includes a network autoswitching feature and can detect from which network it is receiving data. This enables you to send data through different networks without having to change the interface settings. Memory The plotters have a standard 4 megabytes of onĆboard random access memory (RAM). They also have one RAMĆexpansion socket, which can hold an optional 4Ć, 8Ć, 16Ć or 32Ćmegabyte, single inĆline memory module (SIMM). The maximum RAM is 36 MB.
