Therefore, successful communication is having a Controlling device properly control a Tributary device. A Controller cannot control another Controller (or a TRIB control a TRIB) device. 1-12 Utah-400 Data Router...
  • Page 23 UT-400 Data Router Functional Description When an operator has multiple devices to control, it is convenient to use a Data Router to con- nect the devices together. This allows the operator to control many different TRIB devices from his single CNTL device. With a data router between the CNTL and TRIB devices, it is now important to properly manage and configure the ports of the data router to maintain com- munication.
  • Page 24 If your data router consisted of devices that were only Controllers and Tributaries, it would be quite simple to configure and use. The router ports would always be in their proper mode to allow communication with their devices. Therefore, whenever you route one port to another, 1-14 Utah-400 Data Router...

    All differential transmit and receive signal-pairs in the data port matrix have provision for line- to-line termination resistors. As the Utah-400 Data Router is shipped from the factory, all sig- nal-pairs have their termination resistors, nominally 100 ohms, enabled. This configuration will cover the bulk of applications, but there are some special circumstances that may require dis- abling certain termination resistors.
