MoTeC SDL - Manual (Page 59)

MoTeC Appendices 57
Appendix J: USB Wiring
The USB connection should be made by wiring a USB cable to the SDL main
connector as shown below:
The USB cable should have a type B socket so that a standard USB A to B
cable can be used to connect between it and the PC. MoTeC can provide a
suitable cable (these are not commonly available).
Note that the maximum length from ADL to the PC is 5m (16ft) when using a
normal USB cable. This can be extended in steps of 5m (16ft) up to a
maximum of 25m (80ft) by using Active USB extender cables or hubs.

It is recommended that the USB

Tefzel to avoid wire breakage
Maximum length 5m (16ft) including the cable to the PC
Note: When inserting the pins into the Autosport connector check that all the
pins are latched correctly by pulling on each wire – it is very easy for a pin not
to latch correctly which will give an intermittent connection.
