Note that the Scom factory still supports all of the 5K, 6K and 7K controllers, including spare parts stock.

The Scom corporate web site has a wealth of information on the Resources page at http://www.scomcontrollers.com/resource.shtml.

The 2.04x version of the firmware for the 7K was developed by Vyex (from the Scom 7K 2.03x firmware) to integrate the new Digital Audio board. A number of very useful features were added at the same time (like an IF-THEN-ELSE construct)... Support for all 2.04x issues is provided by Vyex, with contact information on their web page.

Sample programming for the S-Com repeater controller line Programmers would call these "code fragments" - just little tricks and treats that others have developed and decided to share. By Joel Huntley WA1ZYX (off-site link)

One method of connection of a repeater controller (the S-COM 7K) to the Micor station By Bob Hoffman N3CVL (off-site link)

Another connection of a repeater controller (an S-COM 7K) to the Micor Unified Chassis Station By Joel Huntley WA1ZYX (off-site link)

Interfacing a GE Mastr II Base Station / Repeater to a S-Com 5K or 7K (19kb PDF file) By Bob Schmid WA9FBO of S-Com, LLC. (Also applies to the 6k with connector pin number changes) (off-site link)

Interfacing a Uniden Repeater to a S-Com 5K (1mb PDF file) Just change the pin numbers for the 6K or 7K

Programming your Scom 5K, 6K or 7K repeater controller without a radio or a phone line The pre-7330 S-Com controllers do not have a serial port. Here's how to get around that. By Mike Morris WA6ILQ

Recovering the User Function Outputs from an S-COM 7K Eight additonal digital outputs are available from a 7K controller. Here's a schematic of the hardware to do it. By Andy Zorca WJ9J

Analog Audio Delay Module Schematic (ADM) This is the early analog delay module.

Digital Audio Delay Module Schematic (DADM) This is the later digital delay module.

One trick that has been done to confuse folks that want to play with your system is to use a courtesy tone that is commonly used by another brand of controller. The courtesy tones that were factory default on the ACC RC-850 are documented on this ACC courtesy tones page.
