ContentHardwareGCA


By Peter Giling

On Paco's website an interface can be found between XpressNet and PC.
I had a request to make this board, so here it is.

The hardware

This board is profesionally made, with sikscreen print and through hole connections.
Very easy to assemble.

Type

  • LI101

Line settings

  • 9600, 8, n, 1

Handshake

Limitations

Because Xpressnet runs with 62500 baud this interface can only be used for small layouts and is not capable of handling data traffic boosts.
The standard Lenz Xpressnet USB Interface uses a baud rate of 57600 which is also not acceptable for handling data traffic boosts.1)


1)
The Ethernet interface should solve this issue.
