Extended Configuration Diagram
Plug the terminal block back into channel A on the front panel of the 
AxisLink option.
If you are using the standard or extended length AxisLink 
configurations, select the desired AxisLink address (0 - 7) for this 
motion controller using the Address selector switch on the front panel. 
Only positions 0 - 7 on this switch may be used as AxisLink addresses–
do not select positions 8 or 9. 
Connecting DH-485 (Optional)
If serial port B has been configured for DH-485 communications (see 
Configure the Serial Ports earlier in this section), plug a 1747-Cxx 
DH-485 cable into either of the DH-485 connectors (RJ-45) on the 
IMC-S/23x front panel. The two DH-485 connectors are internally 
wired in parallel, so either one may be used. The second connector is 
provided to permit easy "daisy-chaining" of multiple devices on the 
DH-485 network. Connect the other end of the 1747-Cxx DH-485 cable 
into a PanelView 550 operator terminal or 1747-AIC DH-485 link 
coupler for connection to a DH-485 network.
The IMC S Class does not provide 24V DC power on the DH-485 
connectors for powering external equipment. Refer to the 
Allen-Bradley publication "Data Highway/Data Highway 
Plus/DH-485 Cable Installation Manual" (1770-6.2.2) for more 
information on DH-485 cabling and the user manuals for other DH-485 
devices for information on powering them.
