The 1769-ASCII has Two (2) individually isolated ASCII ports. Each port may function simultaneous at different configuration and communicate to different set of devices. The ASCII ports are capable of being configured as alternating mode or dual simultaneous mode and can be used as RS233 / RS422 (Port1) and RS485 (Port 2) independently.

The 1769-ASCII has a power supply distance rating of 4 modules. This means that the module must be installed not more that Four (4) modules away from the 1769 CompactLogix Power Supply. It is backplane powered and may connect to any adjacent module including the 1769 CompactLogix Controller. In a MicroLogix system, the module is installed beside the base unit or to an adjacent 1769 Compact module. In both instances, the module does not require an external power supply.
