1.1200 COMMUNICATION MODULES. 



1. 1210 Data Telemetering Module. (96) 



Purpose: To accept the output from up to six standard 

 data sensors and transmit this information to the 

 surface monitoring and recording unit. 

 Specifications and requirements: 



(1) Operating environment: 



(a) Temperature: -2 to 50 C. 



(b) Depth: Maximum of 12,000 m. 



(c) Cable length: Maximum of 18,000 m. 



(2) The total underwater system including the sensors 

 shall not require more than one 3-conductor cable 

 excluding the strength member. This cable shall 

 supply the required power. 



(3) The total system may have up to 20 telemetering 

 modules on one cable. 



1. 1220 Cables (A family of improved steel cables which contain 



electrical conductors) (76,000 m.) 



Purpose: To serve as towing, trawling, and support 



cables for research survey and commercial fishing gear 

 and to serve as electrical conductors for instruments 

 and equipment. 

 Specifications and requirements: 



(1) Must be compatible with anticipated uses in tele- 

 metry, television, control, lighting, fish shocking, 

 and power supply. 



(2) Must be able to withstand severe conditions of 

 pressure, temperature, tension, torsion, shock, 

 chafing, abrasion, vibration, and repeated bending 

 over small radius sheaves. 



(3) Must have life expectancy greater than presently 

 available cable.
