What is the Predrilled LCD front panel?
- This is a rectangular piece of aluminum with predrilled holes for LCD display, 3 buttons and LED diodes. It also has 4 holes in the corner so you can easily mount this to your case. This makes it much easier to mount the transmitter into a nice looking case (eliminates the hard work with the LCD). This is of course an optional item.

What is the RS232/USB IO board and why do I need it?
IO board is required, if you want to control STMAX1000+ remotely via PC. It plugs into the LCD control module. This board does not fit into handy enclosure that we sell.

This add-on card lets you connect this transmitter to the PC via Ethernet network. You can control and monitor the status of your transmitter over Ethernet or Internet. This is of course an optional item. This board does not fit into handy enclosure that we sell.

What is the Software+IOBOARD for changing logo?
This is a combination of special unlocked version of software and RS232 IO board, which is required to control STMAX1000+ remotely via PC/RS232. It plugs into the LCD control module. Software lets you change welcome text (logo); you can replace that text with your company name for example. Your customized text will be saved and used at every power-up. This is of course an optional item.

What is the Empty enclosure for STMAX1000 for?
This is a very practical enclosure with all holes predrilled. You can install the STMAX1000 inside. A fan is not needed. Holes for the LCD are predrilled as well. No text or brand name is printed anywhere on this box.
