SWITCHERS
8
The MX2216RM Switcher is also designed to send
feedback commands from the switcher to the
control system when the buttons on the front panel
of the switcher are pressed.
The Feedback codes are as follows:
Key
pressed
Description Feedback
Code
1 Input Select [INP1]
2 Input Select [INP2]
3 Input Select [INP3]
4 Input Select [INP4]
5 Input Select [INP5]
6 Input Select [INP6]
STAND BY All Outputs OFF [INP0]
RESET Reset [RSET][INPx]
The following commands are added to the
standard set of commands in order to facilitate
control of multiple units using a single RS-232
control port. These commands are available on the
switcher that has firmware revision number: 2.0.
Use [VERN] commands to determine the firmware
revision. These commands add additional flexibility
to the switcher.
[InnOmm]
nn - Input Number 00 to 99
mm - Output Number 01-99
This command connects any input to any output.
The switching occurs as soon as the command is
completed. The input 00 is used to disconnect a
particular output from any input. For example,
command [I00O01] will disconnect output 1 from
any input.
[OUTmm]
This command sets the MX2216RM Switcher to
respond to any specific output only. The default
setting is output 1.
[SETxnnmm]
x - select input number
nn - Minimum input number
mm - Maximum input number
This command is designed to allow the MX2216RM
Switcher to program each of the inputs to respond
to a selected range of input commands.
For example, if command [SET10104] is issued,
then the following commands will select only Input
1: [I01O01], [I02O01], [I03O01], and [I04O01]. In
other words a range of I/O commands can address
the same input. The default settings for each of the
inputs are as follows: Input 10101, Input 20202,
Input 30303, Input 40404, Input 50505, and Input
60606.
7.3 MASTER-SLAVE CONFIGURATION
These feedback codes allow multiple MX2216RM
Switchers to be connected in a Master-Slave
configuration, if desired.
When the control ports of two units are connected
as shown below, the slave unit duplicates the
actions of the master unit. The same unit can still
be controlled from its front panel or through
another RS-232 control.

A Master-Slave configuration can be achieved also
by Analog Switch Voltage using pin#9 and pin#7.
