INT-485 – RS232 to RS485 Conversion Kit
What is it?
A kit to convert the standard 9-pin RS232 serial connection from a
COM port on a PC into a balanced 2-wire + shield connection on
male XLR.
What is included?
1 x KK Systems “K2” RS232-RS485 converter;
1 x 9 pin D-type male to 3 pin XLR male adapter;
1 x 3 pin female XLR to RJ45 adapter cable.
When should I use this?
If the first unit in the system cannot be placed closer than 25 feet from the PC/Laptop, it becomes necessary to use an
RS485 serial connection. As this is a balanced system and uses higher voltages for signalling, it is more robust and can
travel distances up to 1000 metres down simple balanced mic cables , or a multicore channel.
What else should I know?
The standard “K2” converter has a set of DIP switches to adapt the system for various uses. These
are set correctly by XTA when leaving the factory and should not be adjusted. If for any reason
they are different, the correct settings are shown in the diagram to the left.
The wiring for the 9 pin D-type to 3 pin XLR is as follows:
D-type XLR
1 1
3 2
8 3
The wiring for the 3 pin XLR to RJ45 is as follows:
RJ45 XLR
1 1
2 2
3 3
The converter requires no external power and no drivers need to be installed.
Where do I get one?
This kit can be purchased from your local XTA supplier or directly from XTA by credit card. See the end of this document
for details.
XTA Part Number: INT-485
