Programmable Serial Controllers
This category includes the following devices: DS1100, DS1101, DS1102, DS1202,
DS1206.
All programmable serial controllers have a standard DB9M serial port. Use Tibbo's
WAS-P0005(B) 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 (EM1001, EM2001) and modules (EM500,
EM510, EM1000, EM1202, EM1206, EM2000).
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 Status Green (SG), and Status
Red (SR) LEDs onboard. For other devices you can connect the LEDs externally.
