Are the connections to the Network sockets correct?

I checked them when I built the interface, but I will check again. I will order a few BAT43.

Hi, Additional information: The following program: 10 open#5, neto_0 20 for i=1 to 1000 30 print#5,"Broadcast to another computer" 40 end for i 50 close#5 Will run for 9 iterations (until buffer is full) and will hang on the Q68 with the yellow light ON when my interface is not installed. ...

Your VCC, GND and QLNET pins on the connector are correct. Sorry if I ask something too obvious, but are you aware the Q68 network driver is not part of SMSQ/E and needs to be loaded separately? http://www.dilwyn.me.uk/q68/ndq68_v305.zip I agree this is the first thing to check! Yes the driver was ...

Hi, If you want post photographs of thd Network adapter, maybe we can sort out your problem. Here it is. https://lh3.googleusercontent.com/pw/ACtC-3fHDNjEioM5c4N_RZuSumSSrCksLuPTKj1NYqmkodtIW49wgcMQMqNLjm6_C37VWtrjMFlW0nWDdIyaQ_BI3NqQUYISvXrXjQ7LAMFkOz5rrqkITbCp15ncKTJGF3OPYgAMWF7SjkISBBesCGximfV9=...

I have built the adaptor using the 1N5819 and it does not work

Q68 did not explode and is still working great.

Will need to investigate.

However although I ask specifically for a BAT43 diode, I just realize the clerk gave me 1N5819 diodes instead. Equivalent parts ? My problem with the 1N5819 is that I find no specification for the speed yet. The BAT43 is a relatively fast (5 ns) small signal schottky diode, whereas the 1N5819 is a ...

99.9% sure! Ok good enough for me

Hi, I have built many Q68 QLNET adapters, using the BAT43 diodes, which the QLNET connection worked first time. I can only suggest either replace the 1N5819 with the correct BAT43 diode or try the 1N5819 diode, it may work, but no guarantees. Not working is one thing, but damaging the Q68 is anothe...

Today I decided to built the hardware needed to equip my Q68 with QL network ports. I had procured the parts many weeks ago from a local shop. However although I ask specifically for a BAT43 diode, I just realize the clerk gave me 1N5819 diodes instead. Equivalent parts ? When I look at the specs, t...

Hi Francois, If you fit a switch, what are you wanting to do? I fitted a reset switch on the first 9 production Q68 PCBs, but the fitting of a reset switch will not reset the Q68. So removed the switch from the parts list. Well I installed the switch and it indeed reset the Q68 when I press it. Sam...
