In addition to a Windows® 2000 or XP based computer system, DMTH4s can be controlled by external serial control system using the RS-232 interface, such as those from Crestron® and AMX®.

Two RS-232 cables are provided. They are identified by the color of the cable. The black cable is used to connect a computer system to the DMTH4 and the red cable is used to connect a serial control system such as those from Crestron® or AMX®.

Initial Setup

The initial setup of a DMTH4 system is a relatively simple three step process: connect the unit to the computer, turn on the computer and start the appropri- ate control panel, preset the input, matrix and output source. This process assumes that LecNet2™ and, if necessary, the USB driver have been previously installed. If they have not been installed, please refer to Installing LecNet2™ Software and USB Driver.

1)Connect the computer system to the DMTH4 unit using either the BLACK DB9 to stereo mini (TRS 1/8”) cable for RS-232 communications or the USB cable for USB control. (Both cables are included with the unit.)

Note: Only one DMTH4 unit at a time can be connected to the computer system using a single RS-232 cable. Multiple units may be connected using multiple RS-232 cables, each attached to a separate COM port on the computer system. Multiple units may be connected using multiple USB cables and multiple USB ports on the computer system, or a USB hub attached to the computer system.

2)Turn the computer system on. After the boot sequence is complete, turn on the DMTH4. When the DMTH4 STATUS LED glows steadily, click Start, then All Programs on the computer system

3)Select LecNet2, then select the control panel from

the list for the DMTH4 unit being set up.

4)If the “Just a Reminder” dialog appears, click OK to continue.

5)Click Connection on the Main Menu bar, then select the type of connection between the computer system or external control system and the DMTH4 unit. The choices are:

USB - used when the computer is connected to the DMTH4 unit via the front or rear panel USB port.
