The Link 2 / LINK 97
The ICD Link II host adapters implement the ICD extended command set (corresponding to the SCSI group 1 command set). With this type of adapter the maximum size of the drive is limited to 2TB (2^32 sectors of 512 bytes).
MANUAL INSTRUCTIONS
VERY valued customers,
LINK 97 internally, is a SCSI controller for the Atari ACSI interface. The controller signals the passing of the ACSI (DMA) bus an Atari ST / STE / TT signals from a computer to the SCSI bus.
Internally to the LINK 97, up to 7 SCSI devices are connected. The LINK 97 internally supports the SCSI-II command set according to ICD Convention, the parity bit SCSI and SCSI initiator identification.
As an innovation, the Amplified driver performance is to call on the SCSI side. Thus several meters SCSI cable can be used.
2nd. Innovation is to call the limited SCSI bus sharing.
With the release of the SCSI bus, SCSI bus is released, waits as long as the Atari went through any operation on the SCSI bus. if there is Entry, you must first check the SCSI bus by the other, to see if possibly the Host has been released.
Because of the high efficiency can be connected with little restrictions all SCSI devices, unless the devices can be addressed via an appropriate driver software. The maximum cable length is 3 - 4 meters.
Next, may only be terminated on the last random SCSI bus. The INTER LINK 97 is itself passive Terminated.
CONTENTS OF PACKAGE
- 97 Internal Link
- DMA cable with two 19 pin connectors
- Y for the power supply cable
- this guide
- Floppy disk with the driver software, except the hardware packet
CONNECTION
the link 97 is internally connected to the 19 pin cable from the dma dma in socket of the link 97 internally connected to the 19 pin ACSI (DMA) a connected socket ATARI computer. to the 50 pin connector to the SCSI devices via a 50 pin ribbon cable connected, such as hard disk, removable drive, CD-ROM drive, removable drive, or phase flatbed scanner connected. the assignment of the 50 pin connector corresponds to the Occupancy ACCORDING to SCSI standards (see figure on the last page).
ACHTUNG! ATTENTION!
OTHERWISE there is danger of destruction!
TERMINATION
if you want to connect multiple SCSI devices , This must be properly terminated. If only one SCSI Device to the LINK 97 is closed internally, it must be terminated. If several devices connected to the voltage supply LINK 97, only the last SCSI devices on the SCSI bus must be terminated. For all other SCSI devices, the terminators must be removed. As the terminators are removed or turned off, the descriptions refer to the respective SCSI devices.
SUPPLY VOLTAGE
The link 97 is supplied with +5 volts from the scsi bus. If This voltage is the SCSI cable 26 (TERMPWR) is removed. The LINK 97 will not function, so is to also(wise to)check whether the voltage of the SCSI devices on pin comes 26th If this is not the case must be tested on whether via a jumper or switch this voltage can be switched on. As funtioniert, is described in the instructions for SCSI devices. Provides a SCSI devices without SUPPLY VOLTAGE (TERMPWR), so please get with your distributor.
INITIATOR identification
The LINK 97 has an initiator identification. The LINK 97 must have fixed the ID of 7
The INITIATOR identification is necessary for newer disk generations, such as Quantum empire / fireball. Initiator in the phase is determined, which has the computer ID, which should be the highest in the control.
