MAX4358 Evaluation Kit
General Description
Features
o Proven PC Board Layout
The MAX4358 evaluation kit (EV kit) is an assembled and
tested circuit board that demonstrates a crosspoint
switch with support for an optional on-screen display cir-
cuit. The MAX4358 is a 32 x 16 crosspoint switch with
fast multiplexer inputs and partial update capability. The
EV kit provides access to four of the inputs and four of
the outputs. Windows 95/98® software provides a handy
user-interface to exercise the MAX4358’s features.
o Convenient On-Board Test Points
o Fully Assembled and Tested
o Optional On-Screen Display (Companion Board)

2) Connect the 25-pin I/O extension cable from the
computer’s parallel port to the EV kit. The software
uses a loopback connection to confirm that the cor-
rect port has been selected.

puter by running the INSTALL.EXE program on the
floppy disk. The program files are copied and icons
are created for them in the Windows Start Menu.
The Reset menu can be used to reset all of the main
window’s drop-down combo boxes to Disabled, their
initial state. Reset Software only changes the controls in
the main window; it does not affect the hardware. Reset
Hardware pulses the hardware reset signal, placing the
MAX4358 in its initial state with all outputs disabled.
6) Turn on the power supply.
7) Start the MAX4358 program by opening its icon in
the Start Menu.
Supporting Larger Crosspoints
Up to sixteen MAX4358’s can be daisy-chained togeth-
er to form a larger crosspoint matrix. In this configura-
tion, each MAX4358 should have a unique address
selection, set by inputs A0–A3. Although the evaluation
software is only designed to control a single MAX4358,
it can target any of the sixteen A0–A3 addresses, by
setting the corresponding A0–A3 check boxes at the
top of the main window.
8) To route the signal from input IN00 to output
OUT00, go to the Output 00 combo box, and
change the selection from “Disabled” to “Input 00”.
Optionally change the gain to “1V/V” or “2V/V”. A
message will appear at the bottom of the screen,
“Pending Update”. Click the “Send 15-bit Update”
button to send the command to the hardware. You
should now observe input signal IN00 appearing on
output OUT00.
Detailed Description
Software Description
✕
U1, the MAX4358, is a 32 16 crosspoint switch with fast
The main window controls a single MAX4358. Each of
the matrix outputs has a corresponding drop-down
combo box that selects its input source. Although the
MAX4358EVKIT board only has BNC connections for
IN00–IN03 and OUT00–OUT03, the evaluation software
can be used to command all outputs. This way, the
evaluation software can be used as a diagnostic during
initial product development.
multiplexer inputs and partial update capability. The
MAX4358 EV kit has BNC connectors for four of the inputs
and four of the outputs. Additionally, eight outputs as well
as OSDFILL0...OSDFILL7 and OSDKEY0...OSDKEY7
connect to the optional on-screen display kit.
Sip resistor pack R1 provides optional 75 termination
resistors on IN00–IN03. Inputs IN04–IN07 also have
75 terminations. Inputs IN08–IN31 are tied together to
test point TP1 and jumper JU5, for all-hostile crosstalk
testing. Outputs OUT00–OUT03 have 75 series resis-
tors for back or reverse termination. Also, outputs
OUT00–OUT07 connect to the optional on-screen dis-
play kit through 27 resistors. The remaining outputs
are left unconnected.
Initializing the Entire Matrix
The entire crosspoint can be initialized by means of a
112-bit synchronous serial command. First, use the drop-
down combo boxes to select the desired input channel
for each output. Optionally set 1V/V or 2V/V gain. Next,
click on the “Send 112-bit Full Initialization” command
button to transmit the command to the hardware.
See Figure 1, MAX4358 EV Kit Schematic and refer to
the MAX4358 data sheet.
15-Bit Update Command
First, use one of the drop-down combo boxes to select
the desired input channel for the single output to be
updated. Optionally set 1V/V or 2V/V gain. Next, click on
the “Send 15-bit Update” command button to transmit
the update command to the hardware.
Troubleshooting
Problem: Cannot find MAX4358 parallel port con-
nection.
Ensure that the I/O extension cable is connected to a
parallel port, and not a SCSI or other type of port. Verify
that the supplied LPTCON.VXD is in the same directory
as MAX4358.EXE. If a local printer driver is installed,
temporarily disable it. The software will not work if the
program icon is dragged onto the Windows desktop;
instead, install the software into a subdirectory, such as
C:\MAX4358. The software can also be run directly on
its floppy disk, as long as both MAX4358.EXE and
LPTCON.VXD are in the same directory.
Options
To make the evaluation software transmit updated com-
mands as soon as the corresponding combo box is
changed, go to the Updates menu and check “Send
updates when control is changed”. To make the evalua-
tion software display each update command before
transmitting it, check “Show alert on updates.”
To observe the command waveforms on an analog oscil-
loscope, use the Repeat menu to make the evaluation
software repeat its most recent initialization or update
command at an observable rate.
