- Page 2 As a repeater the 3-DRX can be also used to extend the length of a digital cable to double that of a “single hop”. In the “transparent” mode the 3-DRX will repeat the same data rate (sampling rate) as the source.
- Page 3 The 3-DRX operates from 90 to 264 VAC at 47 Hz to 63 Hz input making the unit quite versatile. Connectors on the rear panel conform to AES-3 XLR type connectors and AES-3ID type BNC connectors. The 3-DRX can be selected to be bridging input, 110 Ohm or 75 Ohm terminating inputs.

Page 4: Installation
Shielded pair wire should be used to connect to the AES-3 inputs or coax connected to the BNC inputs. The outputs for the 3-DRX are AES-3 OR AES-3ID. Only one output should be used at a time. Select the appropriate output by switching SW-3 #4 ON for AES-3ID (the BNC) or OFF for the AES-3 (XLR) output you are planning to use. - Page 5 8 = EAS Mode (ON) 9 = MUTE (ON) 0 = EXIT Programming Selecting number 1, 2, or 3 will have the 3-DRX bring up either source 1, 2, or 3. ************************************************************************ If number 4 is selected the following will be displayed:...
- Page 6 Note: S1 = Digital 1, S2 = Digital 2, S3 = Analog inputs, “ -> “ indicates source to be brought on line with error (the sequence). One nice feature of the 3-DRX is that if, for example, the unit has Digital input 1 on line and it has a problem AND Digital 2 has a...
- Page 7 Number 8 from the main menu selects whether the EAS mode is on or off. When the EAS mode is active and pins 1 AND 4 are grounded then immediately the 3-DRX will switch to the analog input. As soon as pins 1 AND 4 are released from ground then the 3-DRX will return to the source that was active prior to the EAS selection.
- Page 9 All of the features of the 3-DRX are available through the REMOTE I/O connector as well as a few additional items. To control the 3-DRX a relay (or other dry closure), TTL level device, or open collector device is all that is needed. The remote control inputs to the 3-DRX are TTL with internal pull up resistors.

Page 12: 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. -
