Quick Start
Required Equipment
The following equipment is required:
MAX1932 EV kit
5V, 500mA DC power supply
One voltmeter
(Optional) Windows 95/98/2000 computer with a
spare parallel (printer) port
(Optional) 25-pin I/O extension cable
Procedure with a Computer
Do not turn on the power supply until all connec-
tions are completed:
1) Install shunts on jumpers JU2, JU3, and JU4.
2) With the power off, connect the 5V DC power sup-
ply to the MAX1932 EV kit.
3) Connect the 25-pin I/O extension cable from the
computer’s parallel port to the MAX1932 EV kit
board. The EV kit software uses a loopback con-
nection to confirm that the correct port has been
selected.
4) Install the evaluation software by running the
INSTALL.EXE program on the floppy disk. The pro-
gram files are copied and icons are created for
them in the Windows Start menu.
5) Turn on the power supply. Verify that V
OUT
is
approximately 40V.
6) Start the MAX1932 program by opening its icon in
the Start menu.
7) Click on SPI 3-Wire Parallel Port Diagnostic (Figure 1).
8) Click on Bit-Banging Serial Interface.
9) Enter 0x01 into “Data bytes to be written” and click
on Send Now (Figure 2).
10) Verify that the voltage at the VOUT pad is approxi-
mately 90V.
11) Enter 0xFF into the “Data bytes to be written” box
and click on Send Now.
12) Verify that the voltage at the VOUT pad is approxi-
mately 40V.
13) Header J2 is provided to monitor the parallel port
pins supplying the CLK_P, CS_P, DIN_P (5V sig-
nals), and loopback signal. The CS, SCLK, and DIN
pads on the EV kit’s bottom edge are V
CC
level-
shifted signals from the MAX1841 translator. Both
signal locations can be used for monitoring.
For instructions on selecting the feedback resistors for
other output voltages, see the
Output Voltage Range
section.
Procedure without a Computer
Do not turn on the power supply until all connections
are completed:
1) Remove shunts on jumpers JU2, JU3, and JU4.
2) With the power off, connect the 5V DC power sup-
ply to the MAX1932 EV kit.
3) Turn on the power supply. Verify that V
OUT
is
approximately 40V.
