Introducing the bit "Teleporter"

[Russ White]

From the draft version of the manual, which should be up shortly:

The Teleporter is pretty simple to configure. There is one dip switch that determines if a channel is a LVDS receiver or a transmitter. The 4 switch positions are numbered 0 – 3.
When a switch position is open (off) the corresponding channel is a transmitter. A channel that is a transmitter will receive 3V LVCMOS signals on the SE header position marked with that channel and will output that signal as LVDS on the same channel at the diff/RJ45 connector.
When a switch position is closed (on) the corresponding channel is a receiver. A channel that is a receiver will receive LVDS on the same channel at the diff/RJ45 connector, and output 3V LVCMOS signals on the SE header position marked with that channel.
The PCB marks the polarity of the differential LVDS signals. The PCB also marks the SE channels on the header.

Just a small question, what is the consumption of the board? Thx

It will vary but it should be less than 150ma.

My pair of Teleporters are on their way from the USA. I'm now wondering how best to use them and my final objective (if there's any such thing in DIY Hi-Fi...) is to get my grubby hands on the anticipated TP USB module, have this close to my computer and use the Teleporter betwixt this and my Buffalo II.

Meanwhile, I was intending to utilise the Teralink USB/SPDIF convertor I currently use which has an I2S output via a CAT-type socket but I was wondering if there's a simpler, more effective way of going USB - Transporters -DAC?

Received today the Teleporters, as I understood:

150mA
+5-7,5V

PCM
0 - bit clock
1 - word clock
2 - data
3 - optional master clock (typically not used)

DSD
0 - bit clock
1 - data left
2 - data right
3 - (unused for asynchronous stereo - but coul dpossibly be master clock)

Attached pic, Left teleporter "off" is transmiter right Teleporter "on" is receiver? I have to connect 4 I2S wires and I have 8 holes, wich one have I to use (where is writed SE near the numbers: 0, 1, 2 & 3)?

If you look closely, the holes further from the board edge are connected to the ground plane. Therefore, you want to use the four holes closest to the edge.

[Russ White]

Are those jumpers on the LVDS header on the module on the left? If so remove them, you would never want to do that.

Thanks Brian

How can configure for receiver & transmiter?

[Russ White]

That's what the switch is for - on the left of the board in your pictures.

The LVDS header is there to allow people to use their own RJ45 connector(wired) or direct wire the LVDS signal between two modules.

This also shows the importance of having a manual for the Teleporter.
