Programmable Serial Controllers
This category includes the following devices:
,
,
.
All programmable serial controllers have a standard DB9M serial port. Use Tibbo's
green
serial cable to interconnect the RS232 port of your controller
and the COM port of your PC (or your USB-to-serial adapter).
Shown below is our DS1100 (or DS1101, or DS1102) device. DS1202 and DS1106 are
similar.
Programmable Boards and Modules
Included here are programmable boards (
) and modules (
,
,
).
Updating these devices via a serial port is a bit tricky, as they don't have a proper
RS232 port. There is an easy way out for Tibbo modules that are not embedded into
a host device: Such modules can be upgraded using evaluation (EV) boards. We
offer EV boards for every model of our programmable modules. Unfortunately, there
are no EV boards for our programmable boards. :)
Here is how to wire a board or a module for a serial upgrade:
Only two lines are required — TX and RX. Tibbo boards and modules have
TTL-/CMOS-level UARTS, and so an RS232 transceiver (MAX232 or a similar device)
is necessary to connect the device's TX and RX lines to a COM port of your PC (or
your USB-to-serial adapter). To boot into the update mode of the M/L, you will need
to power the board (module) up while pulling the MD line LOW. For example, you can
connect a push-button between the MD line and the ground. You will also need a
power source that outputs a regulated 3.3V power.
EM1001, EM2000, and EM2001 devices already carry
onboard. For other devices you can connect the LEDs externally.
