Page 5: Overview
7700 MultiFrame Manual 7705AT Fiber Audio Transmitter OVERVIEW The 7705AT series AES Audio Transmitter Multiplexors and 7705AR series AES Audio Receiver Demultiplexors provide an economical method of transmitting up to six AES audio signals (twelve mono), one RS-232/422 control signal, and linear Time Code (LTC) or eight AES audio signals (sixteen mono) using a single wavelength on a fiber optic cable, with minimum latency. -

Page 8: Installation
7700 MultiFrame Manual 7705AT Fiber Audio Transmitter INSTALLATION The one slot 7705AT and 7705AT-8 versions come with a companion rear plate that has a 25 pin female D connector and one SC/PC (shown), ST/PC or FC/PC optical connector. The two slot 7705AT-2 version also has 6 BNC connectors for the audio. -
Page 9: Table 2-1: Db25 Pin Connections
7700 MultiFrame Manual 7705AT Fiber Audio Transmitter AES/DATA/LTC IN: On the 7705AT there is a 25 Pin D connector for connection of 6 unbalanced AES channels, 1 RS-232/RS-422 data channel, and one differential time code channel. The serial port portion of the connector consists of 2 in pins and 1 ground pin. The SEL 4 jumper located at the rear of the module determines whether the port will be operated as a balanced RS-422 Receive channel, or one RS-232 Receive channel (See section 5.2 for... -
Page 10: Optical Connections
The transmission characteristics of the fiber are dependent on the shape of the optical core and therefore care must be taken to prevent fiber damage due to heavy objects or abrupt fiber bending. Evertz recommends that you maintain a minimum bending radius of 5 cm to avoid fiber-bending loss that will decrease the maximum attainable distance of the fiber cable. -
