Hello,

Has anyone had any experience of hooking up an LA4800/3200 to a PC running
it's LATALK Dos software?

The RS423 interface is described as RS232 compatiable but if you plug in a
straight RS232 cable from PC to LA then the PC doesn't see the LA.

I've looked into this further and RS423 is almost a completely different
standard and levels to RS232. So a bit confused as to how the interface is
described as RS232 compatiable.

Thurlby have been brilliant in that they supplied the LATALK software a few
weeks back but with the LA4800 being discontinued and unsupported the
information I need isn't readily at hand.

Any ideas?

Thanks kindly,

Alison

423 and 232 are to all intents the same for the majority of applications - 232 just swings further.

bear in mind that this instrument dates back to when computers other than PCs were not uncommon ,
and so the D9 pinout may not be expecting to be plugged directly into a PC without some
pin-juggling. You may also need to do things like loop back handshake pins.

Start by confirming the TX/RX direction - at the connector, 0V will be in input (receive) and more
than a volt negative will be an output (transmit)
