Setting Up DCS for Serial Communications

Scroll Prev Top Next More

There are a few steps you must take to ensure that DCS’ remote control feature is enabled. See the hardware requirements section of this application for further information on what's needed on the PC from which you will be running this application. These instructions presume a working knowledge of DCS and configuring DCS. If you are unsure of what to do, consult your DCS documentation or contact your DCS support staff.

Once all hardware requirements are met, including proper serial port cable connections, ensure that the DCS unit is set up in the following way:

1.The host DCS must be running in Control Room mode (CR). DCS allows serial communications and control in CR mode only.

2.Use CMCF (DCS' configuration editor) to open and potentially edit your CR.CFG configuration file to ensure DCS' remote control functionality is enabled.
 
In the DCS Equipment section of the configuration file, select the menu item Remote Control and make sure that the serial control protocol version is set to v1.4 and that the Control Channel Initial State for Serial Channel is "Enabled". Be sure to save your changes, if any, before exiting CMCF.

3.You must tell DCS which serial port you are going to use for remote control communications. This is accomplished by setting a file name in the root directory of the DCS unit boot drive (C:\).
 
You should find a file named _REMOT_1.OFF or _REMOT_2.OFF in the boot directory. One of these files needs to be renamed to _REMOT_x.ON, where the "x" value represents the COM port number to use. Typically, you'd use COM2: for serial control, as COM1: is normally used for an audio switcher, if present. DCS reacts to the presence of this file at start-up and enables the COM port hardware on the DCS unit. The file has no contents, it is the file name that causes DCS to take action.

Only one COM port can be enabled on DCS for remote control. If both _REMOT_1.ON and _REMOT_2.ON exist, DCS will end up using the COM port for the file name last detected. Be sure that if both files exist, one is named .OFF to avoid unintended results.

Once all of these settings are confirmed, you would launch DCS as normal, ensuring you use the command-line: DCSCR.
