There is no software or hardware flow control implemented. The RS-232 input has a 6-character buffer and will not execute additional commands until the previous command is fully processed.

7.2 RS-232 PROTOCOL

It is generally recommended to select a single method of control for each application, as the activation of several different controls simultaneously may cause unpredictable results.

The majority of control systems and computers used in presentation system applications use the RS-232 communications standard.

To connect the MX2216RM Switcher to a control system or computer for RS-232 Control, only three pins are required on each port: Transmit (TX), Receive (RX), and Ground (GND). The Transmit pin from the control system or computer must be connected to the Receive pin out of the switcher’s Control Port; do not connect Transmit to Transmit or Receive to Receive.

Commands must be issued as shown, in ALL CAPS and with the brackets [ ] included in the command string. After processing a valid command, an [OK] string will be returned.

The [VERN] command will return the corresponding software version being used by the switcher, such as an error string, [ERR] will be returned.

If the control system being used is not setup to wait for the [OK] string, it is important to include a 100 millisecond delay between each command.
