Re: HP-HIL and USB

Paul Berger

When I search ebay for HP 46021A I see 5 of them right now and at least 2 of them come with a cable.  The 46201A is probably the most common HP-HIL keyboard you will find.  If you are hoping for a 98203C they are indeed very rare.  You are right that the cables are less common but they do come up some times usually in lots with other HP-HIL devices, however as you point out the connectors are available so if need be you should be able to make your own.

On the whole I would prefer a PS/2 to HP-HIL convertor since most USB keyboards I have seen are poor quality.

Hi Chris


The requirement is to use USB keyboards  for items that require a HP-HIL keyboard


You say there’s plenty of HIL hardware in existence  


OK  find me 2  QWERTY key borders and 4 interconnecting cables   they are not that easy to find 


The problem is when the equipment is moved  people throw away the HP-HIL keyboard assuming a new keyboard will do the job


Regarding the sockets are these required as the equipment has the sockets

The item that is urgently required is a standard keyboard interface to HP-HIL

Ie   USB to HP-HIL


I’m not sure whether you’re saying you urgently want to use a HIL keyboard with a USB system, or whether you want to use a USB keyboard with a HIL system. Either way I don’t understand the urgency, there’s plenty of HIL hardware in existence.


The approach I outlined in my previous message should work regardless of which you want, however. The only difference will be in the USB stack & interface on the Cortex M series, whether it acts as a USB device or host. (Though acting as a USB host is going to be more difficult—though just working with average USB HID hardware shouldn’t be too hard.)



Regarding the HP-HIL mail connectors not a problem there are 2 types 


1 Dot   Type   A   part number  1-1761184-1-ND  this goes into the keyboard

2 Dot   Type   E   part number  5-1761184-1-ND  this goes into the equipment


Last time I looked  digeky  had over 200 of each


That’s good, what about the sockets?
