Summary

The AV 610 CaptionPort is a captioning hardware unit supporting serial (RS-232/RS-422) and TCP/IP (Ethernet) control. All commands use a CTRL+A prefix with carriage-return termination. Telnet is configurable via the web interface. No authentication is required for any control channel.

Notes

Serial port 1 supports RS-232, RS-422, RS-422 Sony; port 2 supports RS-232 only. Both use DB-9 connectors. Default serial: 1200 baud, odd parity, 7 data bits, 1 stop bit. Settings sticky across power cycles, configurable via web UI or front panel LCD (System Setup > P1 Mode). Startup Settings editor runs sticky commands on every boot — CTRL+A prefix implied, not entered manually. Web Terminal emulates serial port via web UI.
