RS485 for Xi 80 and Xi 410
The Xi 80 and Xi 410 cameras support a direct RS485 connection. RS485 interface is designed for high-
speed serial data transmission over long distances and as a bidirectional bus system with up to 32
participants. An RS485 bus can be set up as a 2-wire as well as a 4-wire system. For the Xi 80/410 cameras,
it is designed for a 2-wire system. A maximum cable length of 500 meters can be realized. At least a master
and slave is necessary for communication. The master can be a PLC system and the slave is the camera.
RS485 is supported for Xi 80 cameras which have the hardware version 3001, firmware 3023 and at least
the serial number which starts with 1812xxxx. For the Xi 410 it is working for all cameras starting at firmware
version 3815. Here it is important that the communication is just working via Ethernet connection or in
autonomous mode, but not with USB.
The connection for RS485 can be done directly on the terminal block (A and B) which is provided in the
scope of supply of the camera.

The command list and more information can be found on the supplied USB stick under
