Manufacturers' Numbers: Valuable Information from Loy's Toys

Manufacturers' Numbers

Each decoder has two CVs (7 and 8) which provide information about who made the decoder and which version it is.

CV7 is used to identify the decoder version. Each manufacturer has their own system for using this CV, so if you have specific questions about this value, you'll have to contact the manufacturer directly.

CV8 is used to identify the manufacturer who made the decoder. Each manufacturer of DCC equipment is assigned an ID number. Digitrax's ID is 129 (Hex 81), Train Control Systems ID is 153 (Hex 99), and Throttle Up!'s ID is 141 (Hex 8D). When manufacturers make decoders, this ID number is imbedded in CV8.

Decimal Value	Hexadecimal Value	Manufacturer
11	0B	North Coast Engineering
12	0C	Wangrow Electronics
14	0E	PSI - Dynatrol
15	0F	RamFixx Technologies
99	63	Lenz Elektronik Gmbh
129	81	Digitrax
131	83	Trix Modelleisenbahn
132	84	ZTC
133	85	ICC
135	87	CVP Products (Easy DCC)
137	89	A-Train Electronics
139	8B	RealRail Effects
141	8D	Throttle Up! (SoundTraxx)
143	8F	Model Rectifier Corp. (MRC)
145	91	Zimo Elektronik
153	99	Train Control Systems

None of these CVs is modifiable. In some cases, such as with Train Control Systems' CV Reset feature, provision is made to write to one of these CVs. But writing to it does not change it - it just signals the decoder to perform a task elsewhere in the decoder.

Manufacturers' numbers are not intrusive. You do not need to bother with them unless you want to know who made the decoder or which version it is.
