3.6.3
Wiring the Ethernet interface
1. Connect the RFH630 to the PC via an Ethernet cable.
2. Set up communication via SOPAS configuration software.
Important
The Ethernet interface for the RFH630 has an Auto-MDIX function. This automatically
adjusts the transmission speed as well as any necessary crossover connections.
3.6.4
Wiring serial data interfaces
The maximum data transmission rate for the serial interface depends on the cable length
and on the type of interface. The following recommendations apply:
NOTICE
Damage to the internal interface module
If the serial data interfaces are wired incorrectly, then electronic components of the
RFH630 could get damaged.
Observe the information on wiring.
Carefully check the wiring prior to switching on the RFH630.
The wiring is done using the connection module (see
Chapter 3.7.3 Wiring the RS-232 se-
rial host data interface in the CDB620-001, Page 28
Chapter 3.7.4 Wiring the RS-422
serial host data interface in the CDB620-001, Page 29
Recommendation
Use shielded data cables (twisted pair leads).
To prevent interference factors, do not lay data cables over a longer route in parallel
with power supply cables and motor cables, in cable channels, for example.
Termination of the RS-422 data interface
Termination can be implemented in the CDB620-001 connection module. See "CDB620
connection module" operating instructions (part no. 8012119, Ger./Engl. version).
3.6.5
Wiring the CAN interface
The wiring is done using the connection module (see
Chapter Note on using the RS-422
data interface of the RFH630, Page 29
).
3.6.6
Wiring the switching inputs
The two switching inputs "Sensor 1" and "Sensor 2" of the RFH630 can be used for starting
and/or ending the clock reading pulse or for feeding an incremental signal.
They are available both at the connecting cable with a 15-pin D-Sub HD male connector and
when the cable end is open.
