OVERVIEW
The DV-HSW-21CEC is a2x1 HDMI switcher supporting up to 4K x 2K @
30Hz. The DV-MFSW-21CEC is a unique switcher and a must have for
installations spanning new and legacy technology.This switcher has1 HDMI
input supporting resolutions up to 4K x 2K @ 30Hzand 1 VGA (HD-15) input
supporting resolutions up to 1920 x 1200 @ 60Hz. The HD-15 input ispaired
with a stereo audio input on a 3.5mm mini stereo connector. When selected,
the analog video is converted to HDMI and the audio isembedded greatly
simplifying connections and operations downstream. Both of the 2x1 switcher
models feature 4-way control via simple front panelpush buttons, screw
terminal contact closures with LED feed-back, RS-232 serial control, and auto
sense switching technology.Inautosense mode, the switcher will switch when
the current video source being displayed is turned off either via keyboard
function buttons or from signal loss. These options help in making these a
perfect solution for any system.

CEC SUPPORT
The DV-HSW-21CEC and DV-MFSW-21CEC can automatically power-up
displays that have CEC capability when a source isconnected. They can also
power the display offafter the input signal is removed for 2 minutes. Most
brands of displays need to have the CEC control enabled in the menu to
allow this function to work, and of course not all displays support CEC.
Using this new CEC feature along with the auto-sense feature allows users to
simply connect an input cable to a laptop or other source, and the unit will then
switch to that input and turn the display on. Disconnecting the input will turn off
the display after a 2-minute delay.

RS-232 SERIAL PROTOCOL
The DV-MFSW-21CEC and the DV-HSW-21CEC switcher may be configured or
queried via the RS-232 serial connection.
Request/Response Format
All requests and responses will be entirely in ASCII. The requests can be in either
upper or lower case.
All requests will have three characters command field followed by the data
required for that specific request. All requests are terminated with a carriage
return (0Dh), which will be referred to in this document as <cr>. All responses are
terminated with a carriage return <cr> and a line feed (0Ah) which will be referred
as <lf>.

13
Field Separators
Fields are separated by white space, that is any number of spaces or tabs as long
as the entire command is less than 80 characters. A <cr> terminates the
command. Below is an example describing a command.
CON num <cr>
So the actual message would look like this:
CON 2<cr>
Command Request Syntax:
This document uses the following notation when describing the syntax of a
command request:
BOLD – identifies the command
lower case – identifies data to be entered which is described in the text following
the syntax description
" " - entry defined within double quotes is to be entered exactly as shown
< > - entry defined within these brackets is required
[ ] - entry defined within these brackets is optional
{ } - entry defined within curly brackets must be entered at least once
| - a vertical bar denotes a logical choice of entry
* - an asterisk following either [ ] brackets or curly brackets { } above denotes
that data within either brackets or curly brackets may be entered multiple times.
Acknowledging Receipt of Commands
Each request sent to the switcher will have by default two possible responses, an
acknowledgement of a correct request or an error response. The acknowledge
response will be:
Ok<cr><lf>

14
Error Response
It is inevitable that errors occur in the requests sent to the switcher. If an invalid
command is sent to the switcher, the switcher will respond with the message
"ERR: unknown command". If an invalid parameter is sent to the switcher, the
switcher will respond with the message "ERR:" followed by the valid syntax for the
errored entry.
Example:
A connect request with an incorrect input number:
CON 3<cr>
The error response would be:
ERR: CON 3<cr>

Connection Request
The connection request is used to connect one of the two available inputs to the
output.
A connection may be disconnected by using the DIS command (see later in
document).
CON input |"?" <cr>
Syntax: CON <input | "?"><cr>
Where:
CON Connection request header
input Input number in the range 1-2
"?" Request to return the currently selected input
(the front panel LEDs reflect the currently selected input)
(Note: A CON input command will override the disconnected output, ie via
the DIS command. See below for description of DIS command.)
Examples:
To connect input 2 to output, the connection request would look like this:
CON 2<cr>
To request the currently connected input, the connection request would look like
this:
CON ?<cr>
The response from the switcher would be:
CON 2<cr><lf>
If a previously connected input were subsequently disconnected via the DIS
command, then the CON ? command will return the currently selected input.

16
Disconnect Request
The disconnect request is used to disconnect (disable) the output of the switcher.
DIS <cr>
Syntax: DIS<cr>
Where:
DIS Disconnect request header
Example:
To disconnect (disable) the output of the switcher, the user would send the
following message:

The STA request returns the presence of signal on the respective inputs, 1 =
signal present, 0 = no signal present.
STA <cr>
Syntax: STA<cr>
Where:
STA Status request header
Example:
To query for the presence of signal on inputs 1 and 2, the user would send the
following message:
STA<cr>

19
If signal were present on input 1 but not on input 2, the response from the switcher
would be:
STA 10<cr><lf>
If signal were not present on input 1 and present on input 2, the response from the
switcher would be:
STA 01<cr><lf>
Version Request
In order to be able to identify the current firmware version populated in the unit,
the user may request using the VER request. The format for the request will be as
follows:
VER <cr>
Syntax: VER<cr>
Where:
