Typical RSA-1.0 Application
INSTALLATION
When all system components are installed in a central equipment rack or closet, the RSA-1.0(s) should be mounted in a place
that provides easy access should reprogramming or service be necessary. The plastic fl ange extensions and mounting holes
allow vertical installation on a cabinet side or equipment room wall.
The CAT-5 connections between an MZC-66/88 and a RSA-1.0 are RS485 protocol, so the runs can be fairly long. Typical
RS-485 TX/RX, (transmit/receive) allows up to 1000 feet between devices. When using multiple RSA’s, the TOTAL cable length
from the MZC to the LAST RSA should not exceed this specifi cation.
The DB9 connections between the RSA-1.0(s) and the device(s) being controlled are RS232 protocol which has a limitation of
about 50 feet between devices. For best performance try to install the RSA-1.0(s) as close to the device(s) being controlled as
possible.
When using multiple RSA’s, it is recommended that each be labeled with the device brand, type (DVD player, Server, etc) and
model number to assist in servicing and troubleshooting the system when necessary.
CONNECTIONS
NOTE:
The RSA-1.0 has a
DTE
pinout. If the device being controlled has a
DCE
pinout, a pass-through cable, (pin to
pin), should be used. If the device being controlled also has a
DTE
pinout, then a Null Modem Cable should be used.
1. Using a properly terminated CAT-5 cable (pass-through, pin to pin confi guration) connect the
Expansion Loop
on a
SpeakerCraft MZC-66/88 to the
Expansion Port
on a RSA-1.0.
(Refer to Figure 2)
2. Using a properly confi gured DB9 cable to connect the
RS 232 DATA I/O Port
on the RSA-1.0 to an appropriate RS 232
Data I/O Port on the device being controlled.
(Refer to Figure 2)
3. If using multiple RSA-1.0’s using a properly terminated CAT-5 cable (pass-through, pin to pin confi guration) connect the
Expansion Loop
on a RSA-1.0 to the Expansion Port on the next RSA-1.0.
(Refer to Figure 2)
4. Using properly confi gured DB9 cables (pass-through, pin to pin confi guration) connect the
RS 232 DATA I/O Ports
on
the RSA-1.0’s to the appropriate RS 232 Data I/O Ports on the devices being controlled.
(Refer to Figure 2)
5. When all other connections have been made and the system is ready for programming/operation, connect a
SpeakerCraft
PSA-1.0 12VDC 200mA Power Supply
to the
12VDC Power Jack
on each RSA-1.0.
(Refer to Figure
