Hard disk and floppy disk ports
The hard drive is routed through an 80-pin connector on the bottom side of the
board. The Octagon 2060 HDD/FP cable breaks out 40 of the pins into two standard
40-pin IDE hard drive connectors. Note that the IDE connectors do not 5V
to a hard drive.
The hard drive is implemented with a second ATA-4 compliant IDE controller (the
CompactFlash uses the Primary IDE controller). The BIOS supports up to two IDE
drives in addition to the CompactFlash.
A floppy drive is supported through the LPT port. LPT is routed through an 80-pin
connector on the top side of the board. The Octagon 2060 Multiport cable breaks
out the pins into a standard 25-pin LPT port. The Octagon LPT-to-Floppy cable
connects directly into the LPT port and provides a standard 34-pin floppy drive
connector. Note that only the LPT-to-Floppy cable part # 6470 can be used with
this card, as the floppy pin out from the LPT port differs from other cards. Floppy
drive is selected as one of the options in the LPT menu of BIOS Setup.
USB ports
The CS5530A companion chip supports two USB 1.1 channels, which are available
when using an operating system that supports USB. There is no support from
Octagon for DOS legacy USB.
Both channels are open HCI compliant. USB1 is routed through the 80-pin
connector on the top side of the board. The Octagon 2060 Multiport cable breaks
out the pins into a standard USB connector. USB2 is routed through the 80-pin
connector on the bottom side of the board, and uses the Octagon 2060 HDD/FP
cable.
Note that USB devices are hot-swappable when a device is plugged into a standard
USB connector, as pins on the connectors determine the order in which they make
contact. Devices are not hot-swappable when connected to a non-standard header.
You can hot swap a device through the USB connector on the 2060 Multiport cable,
or through another USB connector wired to the 80-pin header, but you cannot hot
swap at the 80-pin header itself.
Digital I/O
The 2060 has 16 digital I/O lines on the 80-pin connector (accessed through the
2060 Multiport cable) and an additional eight lines on a separate connector. These
24 digital I/O lines will interface with logic devices, switch inputs, LEDs and
industry standard opto module racks. The I/O lines are 0–5V logic compatible.
They can be individually programmed as inputs or outputs. The 2060 Digital I/O
cable provides connection to the additional eight I/O lines.
Serial ports protected against ESD
The 2060 CPU Card has two serial ports. COM1 and COM2 provide RS–232C.
COM2 also supports RS–422 and RS–485 interfaces. COM1 and COM2 are routed
through the Octagon 2060 Multiport cable for RS–232C. RS–422 and RS–485 are
provided through a separate connector. The 2060 RS-422/485 cable provides a
