Important Message Regarding the Impact of the COVID-19 Coronavirus

S-COM has not been directly affected by the COVID virus -- we're all healthy -- but we have been affected by supply chain issues regarding the availability of certain components used in our products. This is something that is affecting all manufacturers, even the car companies, because virtually all electronic components are now manufactured outside the United States.  Be sure to contact us for product availability.

Q: How do I test my custom words on my Windows PC?

When building a custom audio library from individual words or phrases, it's useful to be able to quickly play those words from the raw files stored on your Windows PC instead of going through the entire process of building and downloading a custom audio library to the 7330 only to find it doesn't work.  The way most of us play a custom word on Windows is to run Audacity, import the file, then play it. (See 7330 manual page 23-13.)

It can be even simpler to play a word with SoX.  (See page 23-11.)  Normally, SoX is invoked at the Windows command line with the program name

Q: How do I use a tail message to report a power failure?

Let's say we want a message to be appended to the Repeater Initial and Normal ID Messages while the repeater is operating on battery power.  We have wired our Logic Input #4 to detect a power failure.  

We program User Message #1 with the speech we want to hear, like this (see page 6-63):

; Say "power fail thirteen point two volts" or whatever the actual voltage is
99 33 0015 9960 0148 0766 9852 01 00 9960 0150 *

You can test this message with this command:

99 34 0015 *

Q: I have multiple linked controllers. How can I direct DTMF commands to only one?

The most common way to execute a macro on only one controller is to use different macro names for each site.  This way the macro names don't collide when DTMF is decoded by multiple controllers. 

For example, you can have control macros to enable and disable transmitters.  You could make the first two digits of the macro name unique and keep the last two digits the same.  So the Enable Transmitter macro could be named 8801 on one controller and 7701 on another.  The Disable Transmitter macro could be named 8800 on one controller and 7700 on another.
