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:

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://188.8.131.52:8000/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:
