Dual RS232 Option Module
Figure 1:
RS-232 Option module
Product Description
The RS232 is a single port, electrically isolated adapter with DB9 male connector for the EC-BOS-8 and EC-BOS-9. An onboard UART supports baud
rates up to 115200. LEDs verify power from the controller and indicate RS232 message traffic.
Module Combinations
A maximum of four RS232 modules are supported. The controller supports a maximum total of four option modules across all option types. If two Dual
RS485 modules are used, only one additional non-RS485 module may be added for a maximum total of three modules.
COM Port Assignments
The EC-BOS has two onboard RS485 ports that always operate as COM1 and COM2. Installed serial option modules continue COM port numbering
based on proximity to the controller, where the option module closest to the controller base operates as the next available serial COM port(s). For exam-
ple, if attached directly to the controller, this RS232 option module operates as COM3.
