RSA-1.0 FEATURES
1. RS232 DATA I/O -
DB9M terminal connects to the de-
vice being controlled via RS232 using a DB9 cable.
2. ADDRESS
SWITCH
-
16 position rotary switch, sets de-
vice address allowing up to 16 RSA’s to be used in a single
system.
3. 12VDC POWER JACK -
2.1mm coaxial jack connects to
a SpeakerCraft PS-1.0 Power Supply for power.
4. PROGRAMMING
SWITCH
-
Two-position switch gets set
to ON position for updating the fi rmware from EZ-Tools.
5. IR HI/LO SWITCH -
Two-position switch sets the IR
IN level. Set to HI when connected to a high IR output
device, (12V; P-P) set to LO when connected to a low
output device, (5V; P-P).
6. POWER
LED
-
Red LED illuminates when RSA has DC
power and completes its internal initialization.
7. CONTROL
PORT
-
4-circuit, 3.5mm mini-jack connects to
PC running EZ-Tools for RSA programming and fi rmware
updates.
8. EXPANSION LOOP -
RJ45 jack primarily used to connect to the
Expansion Port
on additional RSA-1.0(s) when mul-
tiple RSA-1.0’s are used to control multiple RS232 devices in a single system. The
Expansion Loop
and
Expansion Port
jacks are parallel. Up to 16 RSA-1.0’s can be used in a single system.
9. EXPANSION PORT -
RJ45 jack primarily used to connect to the
Expansion Port
or
Loop
on a SpeakerCraft MZC-66
or MZC-88. This connection receives control data from the MZC via RS485. RS232 commands are confi gured in the MZC
using EZ-Tools.
10. IR IN -
3.5mm mini jack receives SpeakerCraft EZ-Code IR commands from an IR control system. These commands are
converted to RS232 commands as associated in EZ-Tools. This jack only functions when the special IR to RS232 Control
Interfacing Firmware has been programmed into the RSA.
11. ACTIVITY INDICATOR -
Green LED fl ashes to indicate activation of internal command data.

RSA-1.0 Features
INTRODUCTION
The SpeakerCraft RSA-1.0 Remote Serial Adaptor provides control of RS232 compatible devices from SpeakerCraft MZC-66 and
MZC-88 A/V Amplifi er/Controllers. It connects to an MZC rear panel Expansion Terminal and is triggered by EZ-Pad Button
presses or remote EZ-Code IR commands (when used to control an MZC-66 or 88). The RS232 Commands are programmed
into MZC Projects using EZ-Tools Programming Software. RS232 commands are stored in the EZ-Tools Command Library and
programmed to keypad buttons using a similar procedure to programming IR commands. New RS232 commands, of up to
100 characters each, can be added to the Library in EZ-Tools via ASCII or HEX data entry.
Up to 16 RSA-1.0s can be used in a single system by setting each RSA to a unique device Address. A data buss can be created
to ‘daisy chain’ the RSAs for ease of installation and connection.
