Handshake enable:
- Enable CTS and/or RTS in configuration memory as described in module datasheet
- Ensure that R49 and R50 (0 ohm 0603 size) are mounted on IESM board. One or
both are by intention not soldered in production to avoid unintentional sleep mode
(see module datasheet)
- Ensure that R51 is not mounted, or de-solder if mounted. R51 is by intention soldered
(pulling CTS high) on some modules to avoid unintentional sleep mode (see module
datasheet)
MBUS protocol modules
See the related document MBUS-CCT or MBUS-DEMO User Manual for a detailed
description on how to use the PC Tools from Radiocrafts for configuration and communication
with the module with the embedded Wireless M-Bus protocol. Follow 1-5 on previous page,
then;
- Start the CCT program
- Connect to the correct COM-port where the Sierra Wireless modem is connected
(write manually 115200 as baud rate if this is not an option in the CCT-menu)
- Wireless communication to another module (or module on a Demo Board) can
directly be done by entering text strings in the Terminal Line. Remember that first
byte in transmission has to be string length byte (including length byte itself, for
instance the text: '0x02' A). Ensure that the module has not entered configuration
mode during toggling by sending “X” (exit from configuration mode) before starting
the communication. Also ensure that there is ticked for “NONE” (no CR or LF) in the
CR/LF selection field
- Enter configuration mode by preparing ‘0x00” (equals length zero) in the terminal
window. Then press the button for configuration mode, send the terminal line when
CCT displays “waiting for a prompt sign (..)”. Read back the module settings via left
arrow
- Change parameters as described in the CCT User Manual
- The CCT-program handles all UART instructions required to enter configuration data
and leave configuration mode and entering terminal mode
