GE 90-30 serial port

[control_dog]

I am working on a 90-30 system with a full rack and no CMM module. The serial port is connected to an HMI. The customer wants to integrate to a PC as well. Is there a product to "split" the serial port allowing communication with both devices without changing hardware?

NO, your best options are either:1. Replace the CPU with one that has extra serial ports (IC693CPU363) or an Ethernet port (IC693CPU374) 2. Replace 2 16pt. input or output modules with a 32pt module. 3. Add a second rack.
