The Command-Line Interface
The Command-Line Interface (CLI) may be used for configuration, monitoring and control. It is
provided to facilitate scripting and as an entry point for integration into existing software
systems. It offers full access to all MERlin features using a standard terminal emulator.
The PE terminal emulator available from
http://www.hilgraeve.com/htpe/order.html
is
recommended as an alternative to HyperTerminal as it is generally more reliable.
The command line protocol is available via the RS232 serial connection for local control and
monitoring using a PC. See the Installation chapter for connector information and pin-out.
Before initiating remote control set the PC serial port as follows:
Speed:
115200 baud
Decoder protocol:
1 start bit, 8 data bits, no parity, 1 stop bit
Interface:
RS232
Handshaking:
RTS/CTS
