General
Remember the following when installing your Impro EC
Communications Distance
RS485 1 (Controller Port) and RS485 2 (Terminal Port)
The RS485 communications distance between the Impro EC
Impro Unit in a cable run, MUST NOT exceed 1 km (1 090 yd). Achieve this by using
good quality screened twisted pair Mylar cable, EARTHED on one side.
Ethernet Port
The Ethernet Controller plugs into an Ethernet Switch or Hub (or other network device),
cable runs for this must conform to Ethernet cabling specifications.
Termination Resistors for RS485 Bus Communications
Long transmission lines or multiple "star" connections, may cause communication
problems. Placing the Terminating Resistor Jumper Link in the LAST UNIT AT THE
END OF THE CABLE RUN should solve the problem (depending on the bus). Refer to
Figure 1 on page 8.
EARTH Connection
In conditions where excessive noise is present connect the Impro EC
good EARTH point. Using either of the RS485 Ports, connect the EARTH Lead to the
"SHD" Terminal. Mains EARTH can be used, but electrical noise may persist. The
