3.3 MEVB INSTALLATION INSTRUCTIONS

MEVB installation requires a user-supplied power supply and host computer. The
host computer must have a parallel port and must run MS-DOS, as required by
ICD32. The following paragraphs explain MPFB connections. Refer to Chapter 2
for instructions to connect the MPB and MPFB.
3.3.1 Power Supply – MPFB Connection
Use MPFB connector J5 (Figure 3-1) to connect a user-supplied power supply to
the MEVB. Contact 1 is ground; black lever. Contact 2 is VDD (+5 volts); red
lever. Use 20 or 22 AWG wire for power connections. For each wire, trim back
the insulation 1/4 in. (.635 cm), lift the appropriate lever of J5 to release tension
on the contacts, then insert the bare wire into J5 and close the lever. The MEVB
requires a +5Vdc @ 1.0 amp power supply for operation. A 1.5 amp fuse is
installed on the MPFB +5Vdc power supply input line.
M68MPB333UM/D
