Chapter 1 Introduction
1.1 Introduction
ACARD technology corp. dedicate to make SCSI interface to be a standard
interface in Macintosh with stable function, high transfer rate and very low
cost. The ACARD SCSI adapter AEC-67160M is specificity designed to
speed up the high perform hard disk drive for server, Internet and RAID
system or 3D image, medical imaging, CAD/CAM designer. The AEC-
67160M is a high performance PCI Bus to a single channel Ultra160 SCSI,
Low Voltage Differential (LVD) adapter.
The AEC-67160M is a high performance PCI-to-Ultra160 SCSI adapter.
With full features of the PCI 32-bit bus master transfer capability and PCI
enhanced data transfer commands (133MB/s). It offers real PCI Plug and
Play, and Scatter/Gather function to improve performance for multi-tasking
OS.
The AEC-67160M supports peripheral devices which conform with SCSI-1,
SCSI-2 and SCSI-3. For the bootable SCSI adapter AEC-67160, the
biggest advantage the adapter is a new generation of SCSI technology that
expands SCSI performance from 40 MB/sec to 160 MB/sec. In addition to
providing much greater performance, Ultra160 SCSI increases the
maximum allowable cable length from 3 meters to 12 meters for improved
connectivity and flexibility. It supports Mac OS 8.5, OS 9.x and OS X all
with the same firmware.
The key SCSI chip from ACARD is ATP880 32-bit RISC engine which
highly integrated with arbitration, disconnect, reconnect, parity generation
and checking on both data ports, synchronous data transfers with PCI PnP
specfication. Also, the SCSI chip allows the ACARD SCSI adapter AEC-
67160M to be backwards compatible with previous generations of SCSI
products, while allowing newer Ultra160 SCSI devices to operate at the
higher 160 MB/sec rate and increased cable length.

Chapter 2 Hardware Installation
2.1 Installing the Ultra160 SCSI Adapter
Step 1: Turn off the Mac computer.
Step 2: Plug out the power core and all the connection of external devices
from your system.
Step 3: Referring your original case
user’s manual to see how to
open your case.
Step 4: Select one unused PCI
expansion slot of your
computer. Unscrew the slot
cover and remove it.
Step 5: Remove the SCSI host
adapter from the anti-static
bag and hold its metal bracket
part.
Step 6: Plug the AEC-67160M SCSI adapter card into the unused PCI slot
with care on the bottom of edge. Then fit the adapter bracket on
case frame just like a slot cover.

2.2 Installing Internal Drives
Power Connection
For internal devices, connect DC core power directly from power supply to
device.
Cable Connection
For internal connector
Step 1: Identify number of pins on the connectors, either adapter or device.
Then, prepare a ribbon cable whose connectors match your need,
e.g. 50-pin to 50-pin, 68-pin to 68-pin, or 68-pin to 50-pin.
Step 2: Find out where each pin-1 of connectors located on the cable and
host adapter. Then connect one end of SCSI cable to the
connector of host adapter aligning with pin-1 to pin-1.

8
AEC-67160M Ultra160 SCSI Adapter
Note: Usually, a color wire on the edge of cable indicates pin 1 of
connector, and a mark also shown on the adapter board.
Step 3: Find out pin 1 of the connector on your device.
Step 4: Select one available connector on the cable, then plug it into your
internal device connector aligning with pin-1 to pin-1.
Step 5: If you have two or more devices, please repeat Step 2 and Step 3
to install you remaining devices.
Step 6: Please set the last SCSI device terminator on.
Note: For terminating your internal SCSI device, please refer to
your original SCSI device supplier or manufacture.
Step 7: Identify your devices ID number, that is, you have to set all your
internal SCSI devices an unique ID number to avoid hardware
conflict.
2.3 Installing External Drives
Power Connection
For external SCSI devices, you need to connect the power core to turn on
your external device.
Cable Connection
There are two different ways to make external cable connection when
connecting to only one device or connecting to more than one devices.
1. Connecting to only one device
Step 1: Identify number of pins on the connectors, either adapter or device.
Then, prepare an external cable whose connectors match your
need, e.g. 50-pin to 50-pin, 68-pin to 68-pin, or 68-pin to 50-pin.
Step 2: Plug one end of the high-density external SCSI cable into the host
adapter connector.
Step 3: Plug the other end of this SCSI cable into one connector on the
SCSI device that you wish to connect.

9
AEC-67160M Ultra160 SCSI Adapter
2. Connecting more than one devices
One of the SCSI features is that you can connect two or more devices
simple by place them one after another to the host SCSI adapter serially.
Step 1: Make sure the external SCSI cable is match to the numbers of pin
of external SCSI adapter and devices.
Step 2: Plug one end of the high-density external SCSI cable into the host
adapter external connector.
Step 3: Plug the other end of the external SCSI cable into one of the
connectors on the SCSI device that you wish to connect.
Step 4: Take another external SCSI cable and plug it into the connector of
previous device. Connect the other end of the external cable to the
next SCSI device that you wish to connect.
Step 5: Repeat Step 4 as number of devices is required to be connected.
Step 6: Disable all SCSI devices’ terminators, except leave the end one to
be enabled.
2.4 Installing Both External and Internal Drives
Both external and internal devices can be installed by one adapter at the
same time. AEC-67160M, can maximum connects up to 15 devices totally.
Please ensure that the last device’s external and internal cables.

SCSI card automatically. For advance Mac users, you may try to find out
and check the system information. Follow the instruction below to see how
to check the system information.
Step 1. Click on Apply Logo and choose “Apple System Profiler” to show
your hard disk drives information.

Chapter 4 Troubleshooting
If you install the AEC-67160M and it does not function properly, follow the
troubleshooting below.
1. Check power supply.
When starting to check the malfunction devices, you should check the
power status (ON / OFF).
2. Check host adapter.
Verify the adapter card is seated in its slot on the motherboard.
3. Check all connectors and cables.
Check power connector, SCSI connector, IDE connector, device power
connector, and ribbon cable are connected well. Ribbon cables are easily
damaged because of un-proper fold. You can try a new cable known to be
good. Make sure no connector pins are bent. Verify pin 1 on the interface
cable is aligned with pin 1 on the drive and host adapter.
4. SCSI ID conflict.
If you have multiple SCSI devices, please make sure that ID of the SCSI
device do not duplicate. To reduce the chance the ID switch malfunction, it
is recommended to test it individually.
5. Poor external cable problems.
This may happen if the daisy chained with many SCSI device and some of
the external cables are not the high density 50 pins (or 68pins UW-SCSI)
cables. The 25pin to 50 pins SCSI cable has weak grounding, so if the
daisy chained with more SCSI device to system through the 25/50 pins
SCSI cable and having intermittent failure, it is recommended that you
change this cable with another better quality one.
