1 Overview This Installation Guide explains how to physically install and configure Adaptec APA-358 MiniSCSI™ EPP Enhanced Parallel-to-SCSI host adapters. Your adapter has been designed to provide simple, flexible control of most SCSI devices. The adapter’s ultra high-speed operation enables it to be fully compatible with enhanced parallel ports (EPP), offering excellent performance while remaining compatible with bidirectional and unidirectional ports found on many older computer systems.

This section gives you a brief overview of the Enhanced Parallel Port (EPP) design and how the adapter functions to incorporate the increased performance of EPP. EPP is a major breakthrough in enhancing parallel port performance.
3 Host Adapter Layout This diagram shows the APA-358 components. 4 Default Settings The MiniSCSi EPP operates correctly with its factory default settings in most PCs.
Connecting the MiniSCSI EPP WARNING: Turn OFF the computer, printer, and SCSI devices when connecting or disconnecting the MiniSCSI EPP. This protects against damage to any components. Connect the MiniSCSI EPP parallel port connector to a parallel printer port on your computer. You may use either LPT1, LPT2 or LPT3—the MiniSCSI EPP drivers automatically detect which port is in use.
Assigning SCSI IDs If you connect more than one SCSI device to your MiniSCSI EPP simultaneously, make sure that each device’s SCSI ID (device number between 0 and 6) is different; ID 7 is reserved for the adapter and cannot be changed. IDs must be different to prevent conflicts when the adapter communicates with the devices. See your SCSI device documentation for details. Terminating the SCSI Bus The SCSI devices on both ends of the SCSI bus must be terminated.
Caution: If you disconnect your SCSI device(s) from the MiniSCSI EPP while in use, the adapter loses power and cannot recognize the device(s) when reconnected. Reboot your computer in this case. Connecting the Printer Connect a standard parallel printer cable to the MiniSCSI EPP printer passthrough connector if you wish to simultaneously use a parallel printer with your MiniSCSI EPP. No special configuration or switching is needed to use your printer. For U.S.
Note: You cannot boot from a device connected to the MiniSCSI EPP because your computer cannot boot from a device connected to the parallel port. The MiniSCSI EPP device drivers must be loaded during the boot process from another device. ■ Make sure all cables are properly connected. ■ Make sure all SCSI devices have unique SCSI IDs. ■ Make sure the SCSI bus is properly terminated. No SCSI Host Adapter Detected Message Appears at Bootup The MiniSCSI EPP requires SCSI TERMPOWER to operate.
bootup. The simplest solution is to change your computer’s parallel port hardware to LPT2 or LPT3, or change your network redirection to a different port. The MiniSCSI EPP Does Not Function 1 In the mode configuration switch /Mnm at the end of the line device=[path]ma358.sys in your config.sys, set the value of n to 1. The /Mnm switch must have both n and m values specified. For example, enter /M70 (n or m must be set to 0 if not being used). (See Device Driver Options in the Software User Guide.
value that works with your EPP; typically the value of 2 works with most parallel ports with this problem. Caution: If your MiniSCSI EPP still does not work after trying all these tests, it may not be compatible with your parallel port. Contact technical support. 3 If you share the MiniSCSI EPP with other systems, set up each system individually for proper performance with the MiniSCSI EPP. Be sure to follow the instructions in steps 1 and 2 to ensure compatibility.
