In reference to your posting in comp.sys.ibm.pc.harware (10048):

I presume you want to use it for VGA.  If this is so, you need to make an 
adapter cable from an HD-15P at the VGA card to a DB-9S at the multisync.
Typical pinouts are shown below.

          VGA output               NEC input

          1. RED (out)             1. RED (in)
          2. GREEN (out)           2. GREEN (in)
          3. BLUE (out)            3. BLUE (out)
          4. Monitor ID2           4. Horizontal SYNC (out)
          5. GROUND                5. Vertical SYNC (out)
          6. RED (return)          6. GROUND
          7. GREEN (return)        7. GROUND
          8. BLUE (return)         8. GROUND
          9. No Pin                9. GROUND
         10. SYNC (return)
         11. Monitor ID0
         12. Monitor ID1
         13. Horizontal SYNC (out)
         14. Vertical SYNC (out)
         15. Reserved

So you need to make a cable like this

          HD-15P                   DB-9S           FUNCTION

          1. --------------------- 1.              RED
          2. --------------------- 2.              GREEN
          3. --------------------- 3.              BLUE
         13. --------------------- 4.              H SYNC
         14. --------------------- 5.              V SYNC
          5. ------------------+-- 6.              GROUND
                               |-- 7.
                               |-- 8.
                               +-- 9.

Set the switches on the NEC to ANALOG, MANUAL, and 64 COLOR.  Run a 
program that uses graphics mode and adjust V HOLD for no roll as you 
switch back and forth between text mode and graphics mode.  Adjust the 
CONTRAST and BRIGHTNESS controls until the colors look O.K.

THis information is tested only on the NEC Multisync JC-1401P3A with a 
Video 7 VEGA card.  Any use with other equipment is strictly framming on
the permis of the derialtor, blah, blah, etc.
