Disk Controllers
- 1889: (from Technobox, Inc.)
- SCSI Narrow, Single-Ended. Symbios 53C810A SCSI controller. Supports Rear and Front Panel I/O.
- 2043 -- SCSI Fast/Wide Differential: (from Technobox, Inc.)
- The 2043 is a Fast/Wide, HV Differential SCSI PMC adapter that interfaces a host board PCI bus to a standard SCSI interface via a 53C875. The SCSI bus is presented simultaneously out the front panel using a 68-pin SCSI connector and out the rear 64 user I/Os. A paddle card is available from Technobox to convert the 64-pin P2 connector back into the 68-pin SCSI connector. Each signal can be selectively terminated by a 330/150/330 ohm resistor network by setting a DIP switch. Termination power is provided through a Schottky diode. The 2043 also features a self-resetting fuse that automatically shuts off when excessive termination current is supplied to the SCSI bus. This self-resetting fuse will automatically re-power the SCSI interface following removal of the offending short circuit.
- 2044 -- SCSI Fast/Wide Single-ended: (from Technobox, Inc.)
- Built around a 53C875 SCSI controller, the 2044 provides a single-ended interface between a PCI-bus host board and a standard SCSI device via front or rear I/O connectors. An active termination network for each SCSI signal line terminates the SCSI bus. A DIP Switch on the 2044 allows the user to selectively enable or disable termination. The front panel I/O is supported through a 68-pin connector ( ANSI X3.131 specification). The signals are also available out the rear via PN4. A paddle card is available from Technobox to convert the 64-pin P2 connector back into the 68-pin SCSI connector.
The 53C875 features an intelligent processing engine that executes scripts to reduce processor overhead in handling the SCSI interface operation. The controller supports 1-byte and 2-byte wide SCSI buses (2-byte = "Wide") operating in either asynchronous or synchronous (i.e., "Fast") protocol. The FAST-20 SCSI specification, which permits 20 MB/s or 40 MB/s transfer rate on a 1-byte or 2-byte wide SCSI bus, is supported by the 53C875, enabling synchronous mode transfers at up to 40 MB/s.
The 2044 provides termination power through a Schottky diode as is typically done in most SCSI implementations. A self-resetting fuse automatically shuts off when excessive current is supplied to the SCSI bus. When the circuit fault is corrected, the fuse will automatically re-power the SCSI interface.
This design also supports a Bootstrap FLASH memory option. Typically, however, driver code is installed and runs in the host processor so the Bootstrap FLASH memory is unused.
- 3016/3240 -- IDE Controller (40-pin connector): (from Technobox, Inc.)
- The 3016 and 3240 provide an interface between the PCI bus and as many as four IDE/ATA devices, via two independent channels. Built around a CMD PCI-648 IDE controller chipset, the products support the Ultra 66 data-transfer protocol over primary and secondary IDE channels. On-board LEDs show channel status. The 3016 and 3240 also support slower bus-master data transfer rates to accommodate hard disk drives (HDDs). The primary IDE interface appears at the front panel.
Two connection options are available. The 3016 is manufactured with a 40-pin, 0.100" pitch connector. The 3240 has a 44-pin, 2 mm pitch, Small Form Factor (SFF) connector.
The secondary IDE interface appears at the rear I/O connector (PN4) and can be connected to the VMEbus P2 connector of a host or carrier card. The 3016 and 3240 offer two sites for mounting CompactFlash cards, one per channel. Both sites are configured to operate in true IDE mode. Additionally, each site can be set to operate in either master or slave mode.
- 3145 -- Ultra2 Fast/Wide SCSI: (from Technobox, Inc.)
- The 3145 ULTRA2 SCSI PMC provides a single-ended or low-voltage differential interface between a PCI-bus host board and a SCSI device via a 53C895 SCSI controller. Both front and rear I/O are supported. The front panel interface is a 68-pin connector recommended by the ANSI X3.13. Rear I/O is supported through the board´s PN4 connector. An active termination network for each SCSI signal line terminates the SCSI bus. A DIP switch on the 3145 allows the user to selectively enable or disable termination. This design supports independent selectable termination for the upper and lower SCSI bus bytes.
The 53C895 SCSI controller features an intelligent processing engine which executes scripts to reduce processor overhead. Support is provided for 1-byte and 2-byte wide SCSI buses (2-byte = "Wide") operating in either asynchronous or synchronous (i.e., "Fast") protocol. In Single Ended mode (SE), Fast/Wide operation provides 40 MB/s throughput. In Low Voltage Differential (LVD), 80 MB/s throughput can be achieved.
Selection of either SE or LVD mode is accomplished automatically in the hardware design. The SCSI PMC adapter provides termination power through a Schottky diode as is typically done in most SCSI implementations. A self-resetting fuse will automatically shut off when excessive termination current is supplied to the SCSI bus. The fuse will automatically re-power the SCSI interface following removal of the offending short circuit.
Several LEDS that are visible from the side of the PMC indicate SCSI bus activity. This 3145 also supports the Bootstrap FLASH memory option (128K bytes), whereby users can store boot-up code on the 3145.<BR>3.3V or 5V PCI signaling.
- 3188 -- SCSI Ultra2 LVD/SE PIM: (from Technobox, Inc.)
- Rear I/O interface for SCSI PMCs (e.g., P/Ns 2044, 3145, and 3156). Converts the PN4 signals to 68-pin SCSI connector.
- 3189 -- Dual 10/100-TX Ethernet PIM: (from Technobox, Inc.)
- Rear I/O interface for Ethernet PMCs (e.g., P/N 2894). Provides dual RJ45 connectors.
- 3190 -- Generic PIM: (from Technobox, Inc.)
- Rear I/O interface for 'other' PMCs. Converts the PN4 signals to 68-pin SCSI connector.
- 3473 -- Front-panel CompactFlash Adapter: (from Technobox, Inc.)
- The 3473 Front Panel CompactFlash Adapter, when mated to a host or carrier card, provides an interface between the PCI bus and a CompactFlash device (Type I or II ) mounted on the Adapter. The Adapter also can interface other IDE/ATA devices via its rear I/O connector (PN4) on the Adapter.
Built around a CMD PCI-648 IDE controller chipset, the 3473 supports Ultra 66 data-transfer protocol over its IDE channel. It also supports slower bus-master data transfer rates to accommodate hard disk drives (HDDs) that do not support Ultra 66.
The selected PCI bus is a 32-bit bus at 33 MHz. A built in phase-lock loop generates an internal 66 MHz clock from the 33 MHz PCI bus clock. This internal 66 MHz clock is used to transfer data at the rate of 66 Mb/sec on to the IDE interface.
The CompactFlash site is configured to operate in true IDE mode. Additionally, the site can be set to operate as either master or a slave device. On-board BIOS, provided by CMD and resident in flash memory, supports boot up configuration. This feature is supported only on Intel platforms.
An LED is provided on the Adapter´s front panel to indicate activity. The IDE Controller PMC supports four interrupts. Interrupt configuration is determined by DIP switch settings. Default setting is Interrupt A. Drivers are available from CMD for Windows 95/98/NT 4.0 and 2000.
- 3761 -- SCSI Ultra 160 LVD/SE: (from Technobox, Inc.)
- Based on LSI Logic 53C1000 SCSI controller, the 3761 provides a VHDCI 68-pin front panel interface with user selectable 'active' termination for each SCSI signal. Both LVD and SE modes are supported. Supports 64-bits/66 MHz.
- 4383 - Serial ATA Controller PMC: (from Technobox, Inc.)
- Versatile Serial ATA controller provides four 1.5Gb per second links on a PMC front panel. Additional features are provided for rear I/O. The four SATA ports are accessible at the PMC front panel. Activity LEDs show link activity. Latching style connectors provide secure positive cable connections. The board employs an Intel 31244 controller.
