Technical Support
Various members of the Cactus Intertie System have developed technical designs and requirements for high quality Repeaters and Remote Base operations. The Cactus Intertie System is pleased to share this information with other amateur operators, clubs or systems.
The Palomar Telecom RBC-700 Series Controller was derived primarily from Cactus Intertie System design requirements and original Cactus audio processing designs. The Palomar Telecom RBC-700 Series Controlleris the most widely used controller in the Cactus Intertie System, therefore the Cactus Intertie, Inc. will continue to support the Controller in both hardware and software to the best of our abilities.

Upgrades to Version 2.02
There were two (2) coding errors in the Version 2.01 software that were corrected in the Version 2.02 software.
1) Version 733 Interface Normal command did not disconnect the Remote Base 3 receiver from the Link transmitters.
2) Corrected the Voice Date readout to read year 20XX instead of year 19XX
3) Corrected A/D function. Requires a hardware modification also.
It is strongly recommended that any Cactus Intertie System site that has a Voice Card and is using any Version 2.00 software should upgrade to Version 2.02. as soon as possible.
