Altinex MX2414RM - Manual (Page 10)

SWITCHERS
9
[OUTmm]
This command sets the switcher to respond to
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 MX2416RM
to program each input 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 MX2416RM
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.

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

Master-Slave Analog Switch Voltage Connection
With this configuration the Master unit has ultimate
control over slave unit.
7.4 CONTACT CLOSURE (ONE WIRE ANALOG)
CONTROL
The one wire control is an alternative to a multi-
wire contact closure control. This control pin allows
you to select different channels based on the DC
voltage level on the pin 7 of the 9 pin D connector.
Internally pin 7 is pooled up to 5 volts by 10k
resistor. Thus, by selecting proper resistor values
connected to ground any channel can be selected.
Although the channel selection by the relay contact
is latching and will maintain the last relay selected
channel, it is recommended that momentary
contact closures are not used. A typical resistor
values and wires connections are shown below.
In some cases it may be preferable to use a seven
conductor wire to control the switcher with contact
closures. The RC5204CC adapter is available to
