3-DRX
SECTION 4
REMOTE TERMINAL
The 3-DRX can be programmed and controlled by two different serial interfaces. One is
the remote PC attached to the DB-9 connector on the rear of the 3-DRX. Set up a
remote PC to run hyperterm, teraterm, or equivalent. When running the terminal
emulation software, set it up to run 9600, 8, N, 1. When communicating with the 3-DRX
via this software it will be necessary to press one of the menu keys a few times to get
the 3-DRX to recognize the input. Pressing “0” (zero) will cause the menu to be printed
on the PC.
Another feature of the current 3-DRX is the inclusion of Bluetooth accessability. By
using a cell phone you can control or program the 3-DRX by simply standing near it.
To use this feature, download one of the many applications on Google Play (such as
Bluetooth Terminal) or on Apple store. Once the application is running, and with the 3-
DRX nearby and plugged in, simply look for the Bluetooth device named “Titus-3-DRX”
and pair with it. The paring code is “1234”.
Once the 3-DRX is paired with the cell phone you can press “0” (zero) to access the
menu (may take a few times to get it to be recognized. Now you can access the menu,
program the 3-DRX or control it. For example entering “3” on the keypad on the cell
phone will cause the 3-DRX to switch to Source 3. (Remember that the 3-DRX may take
a few attempts to respond to the commands.
The cell phone will also show change in conditions as they happen with the 3-DRX,
printing which source is being switched to on the screen.
