6. Double left click on the Model Folder (i.e. FireBall) to expand the Command List.
7. Scroll down the Command List to find the desired command (i.e. Play) designated as a RS232 Command with a
“1010” icon.
8. Left click the key on the EZ-Pad to be programmed (i.e. AUX).
9. Double left click the desired command. It will appear in the Button Properties Command List for the AUX Key. Refer to
Figure 115.
With the AUX Key programmed as such, when pressed, the MZC-88 will switch Zone 1 to the Source 8 (Escient FireBall)
audio and video feeds, un-mute the zone pre-amp and issue a RS232 Play command to the FireBall via the RS232 I/O Port on
the MZC-88 Rear Panel.
Repeat Steps 7 through 9 to add RS232 commands to individual keys on FKP-1.0’s and NKP-1.0’s if used.
RS232 Commands can be used in programming Events for various System or Zone ON/OFF sequences as well.

Adding a RS232 Command to a Sequence
ADDING NEW RS232 COMMANDS TO THE COMMAND LIBRARY
New RS232 Commands can be added to the CMD Library. ASCII text strings of up to 100 characters can be added with either
ASCII or HEX code. Additionally, Baud Rate, Data Bits, Stop Bits, Character Delay, Response Length and Response Timeout
can be set to assure proper performance of these control commands. ASCII, HEX and other code parameters can typically be
found in product manuals or manufacturers web sites. It may be necessary on occasion to contact a particular manufacturer’s
tech support to get this information.
In some cases, the EZ-Tools CMD Library will already have IR codes or possibly some RS232 Commands for a particular Brand,
Component and Model, and all that need be done is to add a couple of RS232 commands. In other cases, the Brand, Com-
ponent and Model for which RS232 commands is required may not be in the CMD Library. Start with the appropriate step for
the specific command(s) being added.
1. With EZ-Tools running, open the project for which the new RS232 Commands are required. (If not ready to program a
specific project, open any EZ-Tools project.)
2. Left click the CMD Library Tab.
