488.2 version of MC-GPIB

J1 C24 GPIB port
J2-4 Pads for 5 pin headers
U6 NI 700454-01 Turbo488		 U8 VLSI VGT8001-4057
U32 20.0000 NHz osc
W1 Jumper
 Card from Charles Lasitter (already have one, but...)
U8 is also marked NI NAT4882BPL (line on VLSI VGT8001-4057)

W1 - Shield Ground The MC-GPIB board is set at the factory with the jumper in place to connect the logic ground of the MC-GPIB board to its shield ground. This configuration minimizes EMI emissions.

Caution: The MC-GPIB board meets FCC standards with shield ground connected to logic ground. Removing W1 might cause EMI emissions to exceed any or all applicable standards.

If your application requires that logic ground be disconnected from shield ground, place the jumper on one pin only (or you could remove it entirely!)

The NAT4882 controller chip is fully compatible with the IEEE 488.2 standard. The Turbo488 performance-enhancing ASIC boosts GPIB read and write transfers to rates exceeding 1 Mbytes/s.

Setting the Shield Ground Configuration Jumper W1
The MC-GPIB board is set at the factory with the jumper in place to connect the logic ground of the MC-GPIB board to its shield ground. This  configuration minimizes EMI emissions.

If you are installing one MC-GPIB board, the software assigns it as gpib0. If you are installing more than one board, the board in the lowest-numbered slot is gpib0, the board in the next lowest-numbered slot is gpib1, and so on.
