Verifying
jumpers for various ISA board configurations |
| ISA boards
used for the Micro machine, and boards used for the FLowcon batchers (bulk) are
jumpered per this chart. |
 |
Micro Select Jumper Micro board(s) - jumper E21 to E23
Bulk board(s) - jumper E21 to E22 |
| ISA Interrupt jumpers are only
needed on the primary board. Secondary boards interrupt through the
"daisy-chain" jumper(s) that connect between boards. |
Interrupt Jumper block
Used by the Main Bulk Board
E13 (IRQ2) thru E3 (IRQ12)
RT-Clock is E14: jumper to E8 (IRQ7)
Serial Port IRQ is E15: jumper to E12 (COM4)
|
 |
| ISA: Selects addressing block used
by the board |
 |
Bulk Board Select Primary Bulk board: E30 to E31
Micro Board: E30 to E31
Secondary Bulk board:
E30 to E32 |
| This ISA style board can support up
to three serial inputs per board in RS-232 or current-loop. |
| Scale Serial Chips U25 (top chip) = scale #3
U19 (middle) = scale #2
U4 (bottom) = scale #1
Missing chips need the
jumper (#3) |
 |
| ISA: These chips optically convert
current loop inputs into serial. |
 |
Scale port Optical Couplers U12 (left) is scale #1
U13 (mid) is scale #2
U14 (Right) is scale #3 |
| ISA: This sets the baud rate of the
serial ports. |
| Scale baud rate jumpers Scale #1 is on pin 2
Scale #2 is on pin 4
Scale #3 is on pin 6
Pins 1,3,5,7,9 are baud
rate:
9600, 4800, 2400, 1200, 300 respectively |
 |
| ISA: Gross addressing block - all
boards use this setting. |
 |
Primary Addresses block The first four boards of every
system
get strapped as shown. |
 [not
done - put closeup pictures here of various ISA IRQ jumpering configurations. |
| Jumpering between Flowcon bulk board(s) and Micro boards.
 | One batcher board, one micro board |

 |
| Two Batcher boards, one micro board. This happens to use
two PCI bulk boards and one ISA micro board, which is described in another page. Real
pictures coming... |
