CUE relayCUE-8 - Manual (Page 10)

3.3...............................................RS-232 port connection
The controller ports capable only of RS-232 operation (like S1-S2 on ipCUE-alpha) can also be used,
but RS-232/RS-485 converter like unit PEC25 must be used there. For simple connection to PEC25,
the PEbus cable adapter (GP0045) is enclosed in the packing. Power for RS-232/RS-485 converter
PEC25 is on pin 5 of serial connector of relayCUE-8. Other “Power Express” (PEX) units can also be
connected to this bus (see Important Note below).
Note:
Max. 127 units (relayCUE-8 or any PEX unit) can be connected to PEbus port on PEC25.
Important Note:
If relayCUE-8 and PEX units are to be combined on the same bus, the PEX units must be
installed and programmed using their serial drivers on serial port like any other serial
controlled equipments (similar way like the relayCUE-8) and not by using “Insert Local Panels
and Interfaces” wizard!
