a terminator and a scsi cable are supplied with your scanner.
for safety reasons, never use extension cables for power cords. always make sure that there is no more than one terminator in your scsi chain and that it is placed at the end of the chain. some scsi devices have built-in terminators and must therefore be placed at the end of your scsi chain. please check the documentation of each of your scsi devices if you are not sure whether the device has a built-in terminator or not. your arcus 1200 has no built-in terminator.
if your arcus 1200 is the only external scsi device to be connected to your apple macintosh:
1 place the terminator on the 50-pin connector of the scanner.
2 snap the diamond shaped wire clips into the clip brackets to secure the connection.
3 connect the 50-pin end of the scsi cable to the free side of the terminator.
4 snap the diamond shaped wire clips into the clip brackets to secure the connection.
5 connect the smaller 25-pin end of the scsi cable to the connector of your apple macintosh.
6 tighten the connector screws to secure the connection.
if your arcus 1200 will be connected to your apple macintosh together with other external scsi devices:
if you install the scanner at the end of your scsi chain
1 remove or switch off the terminator from the last device in the scsi chain.
2 connect the 50-pin end of the scsi cable to the connector that has become available on this device.
3 snap the diamond shaped wire clips into the clip brackets to secure the connection.
4 connect the 25-pin end of the scsi cable to the 25-pin connector of the scanner.
5 tighten the connector screws to secure the connection.
6 place the terminator on the 50-pin connector of the scanner.
if your scanner is the first external device of your scsi chain
1 connect the 50-pin end of the scsi cable to the connector of the next device in the scsi chain.
2 snap the diamond shaped wire clips into the clip brackets to secure the connection.
3 connect the 25-pin end of the scsi cable to the connector of the scanner.
4 tighten the connector screws to secure the connection.
5 make sure that the last device in the scsi chain is terminated.
if you install the scanner between two other external scsi devices
1 disconnect the scsi cable from one of these two scsi devices.
2 connect the free end of this scsi cable to the scanner.
3 connect the 50-pin end of the scsi cable (the one supplied with your scanner) to the other adjacent scsi device.
4 snap the diamond shaped wire clips into the clip brackets to secure the connection.
5 connect the 25-pin end of the scsi cable (the one supplied with your scanner) to the scanner.
6 tighten the connector screws to secure the connection.
7 make sure that the last device in the chain is terminated.
