7.3 MASTER-SLAVE CONFIGURATION

These feedback codes allow multiple MX2214RM 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

The following commands are added to the standard set of commands in order to facilitate the control of multiple units using single RS-232 control ports. These commands are available on the switcher that has the 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, the command [I00O01] will disconnect output 1 from any input.

[OUTmm]

This command sets the switcher to respond to a 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 MX2214RM 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], [I04O01]. In other words a range of I/O commands can address the same input. Default settings for each input is as

7.4CONTACT 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 pin 7 of the 9 pin D connector. Internally, pin 7 is pooled up to 5 volts by 10k resistor. Thus, by selecting the proper resistor
