CAUTION
Electric shock
Minor or moderate personal injury
- Connect CIM 500 only to SELV or SELV-E circuits.
7.1 Connecting the ethernet cable
Use RJ45 plugs and ethernet cable. Connect the cable shield to
protective earth at both ends.
It is important to connect cable shield to earth
through earth clamp or to connect cable shield to
earth in the connector.

CIM 500 is designed for flexible network installation; the built-in
two port switch makes it possible to daisy chain from product to
product without the need of additional ethernet switches. The last
product in the chain is only connected to one of the ethernet
ports. Each ethernet port has its own MAC address.

for 20 seconds to Reset to factory default. During this
period, LED1 flashes red and green at the same time to
indicate that a reset will occur.
Every change of the rotary switch setting, when the
module is powered on, will cause the module to
restart.
