Register-Based Programming 53
Appendix B
Remote Module ID
Registers
Reading these registers determines the number and location of E1473A
and E1475A Expander modules connected to E1472A and E1474A RF
Multiplexers.
Module 00 Status:
The base +06
h
register returns module 00 status (RF
Multiplexer relays connected to the RMD0/1 connector). Returns FF11
h
if
the relays are connected, and FFFF
h
if the relays are not connected.
Returns FF00
h
if E1472A/E1473A modules are connected. If you are using
the E1474A to control additional E1473A or E1475A modules, use this
register to verify the relay type.
Module 01 Status:
The base +08
h
register returns module 01 status
(Expander module connected to the RMD2/3 connector). Returns FF11
h
if a module is connected, and FFFF
h
if a module is not connected. Returns
FF00
h
if E1472A/E1473A modules are connected. If you are using the
E1474A to control additional E1473A or E1475A modules, use this register
to verify the relay type.
Module 02 Status:
The base +0A
h
register returns module 02 status
(Expander module connected to the RMD4/5 connector). Returns FF11
h
if a module is connected, and FFFF
h
if a module is not connected. Returns
FF00
h
if E1472A/E1473A modules are connected. If you are using the
E1474A to control additional E1473A or E1475A modules, use this register
to verify the relay type.
Channel Enable
Registers
A read of the Channel Enable register (base +10
h
to 1A
h
) always returns
FFFF
h
, regardless of the channel states.
Writing to the Registers
You can write the following RF Multiplexer registers:
•
Status/Control register (base +04
h
)
•
Module 00 Bank 0-2 Channel Enable register (base +10
h
)
•
Module 00 Bank 3-5 Channel Enable register (base +12
h
)
•
Module 01 Bank 0-2 Channel Enable register (base +14
h
)
•
Module 01 Bank 3-5 Channel Enable register (base +16
h
)
•
Module 02 Bank 0-2 Channel Enable register (base +18
h
)
•
Module 02 Bank 3-5 Channel Enable register (base +1A
h
)
Status/Control
Register
Writes to the Status/Control Register (base +04
h
) enables you to reset the
RF Multiplexer to turn-on conditions (channel 0 to COM 0 on all banks), and
disable/enable the interrupt generated when channels are closed. To reset
the RF Multiplexer, write a “1” to bit 0 of the Status/Control Register (base
+04
h
).
