hi I'm Drew Klaber on today's tool tip I'd like to show you how to enter the
settings menu of a digitech multiplexer
we'll begin by plugging in the supplied USB cable and power cable first I'll
plug in the USB cable second I'll plug in the power cable and then we'll go to
the software to begin I'm going to load the windows device manager to make sure
that I can see that the unit is plugged in notice I do have a Mitutoyo
virtual comport/human interface device where the drivers have not yet
been loaded this is what I expect to see if I do not see this on the listen I
need to make sure that my USB connection is secure and that I am receiving power
to the units since I can see the device in my device manager I need to update
the drivers that came with the multiplexer for this example I've
already copied the drivers from the cd-rom and they're located on my desktop
under a folder called MIG USB drivers as a return to the device manager I'm going
to right click on the device called Mitutoyo VCP/HID device and
I'm going to select update driver I'm going to now select browse my computer
for driver software and I'm going to browse out to the folder that I just
showed you on my desktop
and select okay I have include subfolders checked I'm
going to now select next if you're prompted by Windows security you can
select installed once complete I will get a confirmation screen that the
drivers have been successfully installed and that my MIG box is now on comport
six hit close - in this process and now we can see that the device is still in
my device manager but the icon next to it has changed because windows now
successfully has recognized the multiplexer box once this step is
complete we can now close the device manager the CD included with the
multiplexer has a terminal program that we will use to communicate with a
multiplexer if you already have a terminal program that you wish to use
that's fine as long as you can access any serial port on the computer I'm
going to begin by loading Tera Term once Tera Term is open the default connection
is for a tcp/ip communication setting I'm going to switch that to serial and
you notice this already defaults for comm 6
Mitutoyo device if your unit does not default to this you can select a down
arrow and then select the Mitutoyo VPCHID device from your drop-down list
now I will click OK for my convenience I'm going to maximize the tera term
window from here I'm now going to go to the setup menu and select serial port we
already know that the multiplexer is on comm port 6 but how do I know what the
speed data and parity settings are well we can actually pull that off of the
unit itself as I turn the multiplexer over there's a sticker on the bottom
where I can see what the output is we'll start with rs-232 remember when we
loaded our drivers our computer was set to comport 6 our bottom parity settings
are 9600 in 8:1 I want to make sure that these settings correlate with the
settings that are in my terminal program so we can see here that my comm port is
still set that comm 6 the speed data parody stop it's all of this matches the
sticker I found on the bottom of the multiplexer
unit select ok to confirm these settings once my settings are confirmed
I'm back at the main screen of the terminal program from here i type in SPC
in all caps and now I've entered the setup menu for the multiplexer what's
the main menu is loaded I can see that it's divided into two sections the top
section will show me each individual port for the multiplexer since I'm using
a four port box here I have four different ports that are showing up in
the software and it shows me how they're individually configured the bottom
section of the main menu allows me to go in and make specific changes so that the
Box performs the way I expect it to to save any changes that you make to the
main menu type EX followed by the enter key to exit and save the changes to the
multiplexer to exit without saving any changes type QU followed by the enter
key to exit the multiplexer and not save any changes that were just made thank
