It handles asynchronous serial frames with data bit set to 7 or 8, stop bit 1 or 2, start bit 1, and parity selectable as 1 (vertical) or none — covering common formats like 8N1, 7E1, or 7O1. Its nonprocedural protocol and bidirectional protocol support both polled and unsolicited sends, making it suitable for connecting to barcode scanners, printers, or drives that send data without a request.","metaTitle":"QJ71C24N-R4 Serial Link Module, RS-232","metaDescription":"Mitsubishi QJ71C24N-R4 Link Module for Q-series PLC.
