7. Communications
Infrared (IR)
All products in the range can communicate via an infrared link between adjacent controllers.
It enables the parameters of this product (OEM) to be passed to a product fitted with RS485
(USER).
USER products are fitted with a graphics display and OEM products either have LED’s, or
three digit displays.
This unit is always an IR slave – no set-up or adjustment is needed.
For further information on Infrared and RS485 communication, see User Installation and
Maintenance Instructions.
Important: Do not cover or obstruct the infrared beam between products.
See appendix for further details.
