tetek 0 Posted July 9, 2011 I have a DS2A DVTU DVR that I am trying to connect to using Hyper Terminal. So far I can not. I am using Windows XP and have the cable plugged into com1 on the PC and serial port 1 on the DVR. I have rebooted the DVR so it is "Halted in bootloader". Hyper terminal setting are: 19200 baud Data bits 8 Parity none Stop bits 1 Flow control none I have tried entering "esc" three times and then enter but get no response. Also have tried entering +++ and the enter with no response. Have tried this on three machines of the same type with no luck. Can someone tell me what I am missing? I have verified that the PC's serial port is working. Thanks, tetek Share this post Link to post Share on other sites

Thanks, tetek Its been a while since I have dealt with a DM and Hyper terminal but from what I remember the data pair for the com connection needs to be reversed. sounds like your doing everything else right let me know how you get on Share this post Link to post Share on other sites
tetek 0 Posted July 10, 2011 Thanks for the reply. Are you saying that a "null modem serial cable" is needed? I have a few of these DS2A's and do not want to see them go to waste over bad hard drives. As we all know DM charges way to much for a repair. tetek Share this post Link to post Share on other sites
tetek 0 Posted July 10, 2011 With your help I am now able to use Hyperterminal with the DM units. I was using a pin for pin serial cable. Found a null modem type in my parts and it worked! Some additional info for anyone doing this....I have had no luck using Western Digital hard drives. For some reason the DM unit does not like them. Unfortunately, it's difficult to find anyone other than Western Digital making PATA hard drives. I plan to try and use an IDE to Sata converter. A lot of my customers have these DS2A's and want them rebuilt. Again .....thanks for your help! tetek Share this post Link to post Share on other sites

Again .....thanks for your help! tetek Glad you got it working I now know what a null modem cable is, I have opended plenty of DS2's and found WD drives in them although I do know that DM's can be fussy with there drives. Are you formatting them as FAT32 before installing them? Share this post Link to post Share on other sites
tetek 0 Posted July 11, 2011 I've been using Fat32format on a Windows XP machine. This Western Digital drive is a brand new 160GB. Every time I try it the DS2a stalls and won't boot. This even happens if I have a Maxtor as the master and the WD as a slave. I could of sworn that I used Western Digital in the past on a DM unit and it worked. Back then I used to boot up a PC with a windows 98 floppy boot disk and use FDISK to make the primary partition on the drive. This takes a long time though. It is bugging me that it doesn't work so when I have a chance I will try doing the FDISK that way to see if it works. Thanks, tetek Share this post Link to post Share on other sites

Hi tetek. many people have tried. they just dont see sata drives. if your cusomers are just looking for more storage just add extra PATA (but dont remove the master) if you have just been changing hard drives then you will get errors. the DS operating files are on the firsts partition of the master drive. so that needs to stay in.
