V100-17-RS4X-1 Isolated RS232/RS485 Port for VISION130 and VISION350 Unitronic

V100-17-RS4 (not isolated) V100-17-RS4X (isolated) Serial Modules

• Use these modules to add an additional serial communication port to the controller. 
• Use RS232 to download programs from a PC, and to communicate with serial devices and applications, such as SCADA. 
• Use RS485 to create a multi-drop network containing up to 32 devices. The modules are identical except for isolation.

Module ports are type RJ-11 and may be set to either RS232 or RS485 via wiring and DIP switch settings, in accordance with the table on page 2.

To connect a PC to a port that is set to RS485, remove the RS485 connector, and connect the PC to the PLC via the programming cable. Note that this is possible only if flow control signals are not used (which is the standard case).
