COM port protocol
In this chapter you can read about:
RS485 setting values.......................................................................................................................232
ASCII - record ..................................................................................................................................233
Binary record ...................................................................................................................................234
You can communicate with Compax3 in order to read or write objects via plug X10
( or X3 on the mains module of Compax3M) on the front via a COM port (max. 32
nodes).
As a rule 2 records are possible:
ASCII record simple communication with Compax3
Binary record: fast and secure communication with Compax3 by the aid of block
securing.
Switching between the ASCII and the binary record via automatic record
detection.

RS232:
SSK1
(see page 289)
RS485: like
SSK27
(see page 290) / RS485 is activated by +5V on X10/1.
USB: SSK33/03 (only for Compax3M)
5.1.1.
RS485 setting values
If ”Master=Pop” was selected, only the settings compatible with the Pops (Parker
Operator Panels) made by Parker are possible.
Please note that the connected Pop has the same RS485 setting values.
You can test this with the "PopDesigner" software.
"Master=General" makes all Compax3 settings possible.
You can use this address to allow the master to access multiple devices
simultaneously.
The device address of the connected Compax3 can be set here.
Adjust the transfer speed (baud rate) to the master.
Please choose between
two-wire and four-wire RS485
(see page 53).
Adjust the protocol settings to the settings of your master.
