Use the NCE Packet Analyzer and your computer to view DCC packets being sent by any DCC system. Selectively filter out idle, reset, accessory, function and/or speed packets. Information can be displayed in hexidecimal or our special “verbose” mode that makes it easy to decipher track activity. Requires PC, Mac or Linux computer with terminal program and 9 pin serial cable. Can also be used to monitor NCE Cab Bus activity.
The following is from Mark Gurries outstanding site for NCE.
The NCE Analyzer is compatible with all DCC systems when looking at the DCC track packets. It requires a PC and a terminal emulation program that is typically free. It decodes the DCC packets in real time and dumps each packet to a terminal display in transmission time order. You can selectively filter out idle, reset, accessory, function and/or speed packets. Information can be displayed in hexidecimal or our special “verbose” mode that makes it easy to decipher track activity. However, there is no technical analysis as to the quality of the packets. Both good and bad DCC packets will be displayed. As a bonus to NCE users, the packet analyzer can also be configured to dump Cab Bus commands. Opto-Isolation is offered to prevent track power shorting to “grounded” PC’s when analyzing track power. For complete information, download the NCE manual.
1) PC/MAC with a terminal emulator program.
2) PC/MAC with a RS-232 (DB-9) or USB Serial Interface. Recommend purchasing a RS-232 DB-9 extension cable regardless of what type of serial port your PC has. PC’s and MAC’s with just USB ports will ALSO need to buy a “USB to Serial Adapter” such as Keyspans’ (Tripp-lite) USA-19HS.
3) Flexible Power Supply Options.
a) Cab Bus Power b) Track Power c)+12VDC external wall adapter power with a positive tip 3.5mm connector (Not included).
Strongly Recommend option “c” along along with “opto-isolation” configuration when looking at track power.
