Bob's Blog #9 - Timekeeping

Let’s take a then-and-now look at how generations of S-COM controllers kept time.

The term for what we’re talking about is Real-Time Clock, or RTC. It refers to timekeeping in human terms (time and date) rather than the cyclical clock signal used to synchronize logic. RTC can be implemented in software or with an integrated circuit that tracks time and date independently of microprocessor intervention.

Bob's Blog #7 - Triple Repeater Control

If you own a 7330, you know that its flexibility in port programming is unmatched in repeater controllers.

How did it get that way? Let’s go back some years...

The 7K is in its prime and is our flagship model. It’s designed to support one repeater, one link transceiver, and one control receiver. It’s still doing its job well, but we’re getting more frequent requests to have it control two or three repeaters instead.

Bob's Blog #6: Cabinets

So why are we dedicating a blog to a boring topic like cabinets? Are they made of Valyrian steel?

Nope, aluminum. But we hope you’ll find the details interesting anyway.

Our repeater controller cabinets are made of 5052-H32 aluminum alloy sheet. It’s strong, light, formable, and commonly used for aircraft, marine, and commercial-grade parts.

7330 Firmware and Tools Release 1.7 Is Available!

Release 1.7 of the 7330 Firmware and Tools is now available! Our testers have finished their testing and all feedback has been incorporated into the firmware and documentation.

There are two new major features in this release:

-- new Runtime Variables (RTVs) have been added so that your messages can speak the current values of booleans, software switches, counters, timers, analog inputs, logic inputs and logic outputs.

Bob's Blog #5: Macros

Macro commands have been implemented in every S-COM controller since 1976. Why?

The term dates from mid-1950s computing. It was common for a programmer to enter a short macro instruction to generate a series of other instructions. It saved time, reduced errors, and helped standardize the code.

7330 GUI Programming Utility

Sigrid Company LLC is pleased to announce version 1.0 of P7330, our new GUI programming utility for the S-COM 7330 repeater controller.

P7330 includes these advanced features and more:

    • Message Builder - Create a messages without looking up controller codes.
    • Macro Editor - Create & manage macros with automatic creation codes and password insertion.
    • Macro Pick List - Shows currently defined macros. Drag & Drop a macro from the list to any macro field.
