Ken McGuire got his on 3/15/2003 and found the following:

  • the serial port operates at 38400 baud.
  • Hold down the menu and info button, keep holding them while plugging in the box, "boot" will appear (after about 5 seconds of holding) on the display and some stuff will come out the serial port.
  • the cursor and channel buttons will cycle through a menu: cold, hunt, disp, n dl, run.
  • pressing select at each ot the menu items will do something, and produce data on the RS-232 port.
  • there is a reset button inside that does the same as powering on. labelled SW900.
  • holding just the menu button during reset gets the "boot" display without any serial port activity.
  • the "pcmcia slot" connects to the motherboard via a 24 pin connector J402, so it's probably not true, or complete PCMCIA.
  • there is no video out of any of the outputs, VGA, S-VID, video out.
  • JTAG comes out to J7, a 10 pin header with half the pins grounded.
  • pin-out at: [JTAG pin-out]
  • J7 with connector (it's a .050" spacing): [J7conn picture]

Here is what comes out the serial port at boot time:

  • DCT5000 Boot ROM v1.17
  • Copyright (c) 1999 by General Instrument Corp.
  • SUDB 0xBF000004
  • 58 00 00 00 53 55 44 42 00 00 11 01 07 00 00 00
  • E9 E2 EB E2 01 BC 20 02 74 7B 0B 00 03 10 20 20
  • 20 20 20 20 20 20 30 30 30 2E 00 30 00 00 00 00
  • 00 00 00 00 00 00 00 00 00 00 00 00 00 02 00 BF
  • 00 00 00 00 00 00 00 00 00 00 00 00 00 06 00 BF
  • 00 00 00 00 03 01 CF CA

T0mW found that while holding the INFO button down while powering up, or RESET, it will give a verbose debug of the frequencies it is "hunting" on.

MonMotha got his DCT5000 on 3/19/2003. I haven't done much with it other than take the top off, but I'll update this page as I go. So far I'm just attempting to find some of the missing doc links.

sorphin got both of his DCT-5000's on 3/18/2003, and is doing some digging, also found this link http://24.125.76.224:8000/www.cableboxen.prjct to a page where a guy is working on mapping out how the DCT-2000 and 5000 work.

Here's a list of test points, add to them as they are discovered:

  • TP9 (next to the CPU, towards the back): Pin 76 of CPU - Sys Clock
  • TP11 (Next to U33): SDRAM Clock
  • TP510: Ground

Notes TimRiker "found":

Connect a straight-through serial cable from the COM1 port on the host computer to the RS-232 port on the target system. Make sure that the RS-232 connector is attached to internal connector labelled J800. 9600-8-n-1

Power ON the target board. When it boots, a # prompt appears.

Enter the following commands at the # prompt:

export BOOTFILE=vmlinus
export BOOTHOST=
export NETADDR=
export NETMASK=
export BROADCAST=
export ETHERHWADDR=

TimRiker is not sure if this is after installing a different ROM or something... Still looking.

Ken McGuire searches through the binary images of Tim's ROM and [the original ROM] and doesn't find any of the above strings. Nothing comes out his DCT5000's J800 on power-up either.

Here's the DOCSIS configuration file of the box:

NetworkAccess = Yes

Start ClassOfService
ClassID = 1
MaxRateDown = 1500000
MaxRateUp = 128000
PriorityUp = 1
