Industrial 4100-6038 Dual RS232 Interface Card

The Simplex 4100-6038 Dual RS-232 Interface Card provides two RS-232 serial ports for Simplex 4100‑series fire alarm panels, enabling direct serial communication with printers, CRT displays, modems, or third‑party equipment. It ships as a daughter card in the 4100 family and uses a bank of eight DIP switches (SW1) to set the internal baud rate and the card address for the panel. Jumpers on the card govern how Port A and Port B connect to attached devices, allowing you to tailor each port’s function to your application. This dual‑port RS‑232 module is the standard RS‑232 option for the 4100 line, ensuring reliable serial data exchange within Simplex networks.
