Pro II: Extension and Interface Modules
Pro II-RSxxx Rev. E
ADwin
5.8.6 Pro II-RSxxx Rev. E
The Pro II-RSxxx module has 2 or 4 interfaces of the type RS-232 or RS-485.
The type of interface is selected with the instruction
P2_RS485_Send
.
The names for the module versions are:
– Pro II-RSx-2 Rev. E: 2 interfaces RS232/485
– Pro II-RSx-4 Rev. E: 4 interfaces RS232/485
All modules of the RSxxx-y modules are equipped with the "Quad Universal
Asynchronous Receiver/Transmitter" (UART) controller, type TL16C754 from
Texas Intruments
®
. Functionality and programming of the interfaces are based
on this controller.
Each module is equipped with a freely programmable
TiCo
processor, which
has full access to the RSxxx interfaces. Find more information about use and
programming of the
TiCo
processor in the
TiCoBasic
manual.
If you store a
TiCoBasic
program in the
TiCo
bootloader, the program is auto-
matically loaded into the
TiCo
processor and started on power-up. Thus, the
module can run on its own and independently from the CPU module of the
ADwin-Pro II
system.
The physical difference between the interface versions is their signal level,
which is provided by appropriate drivers on the bus.
