This section describes how to remotely control the Showman 1000 over an RS232
connection using the Command-Line Interface (CLI).
The CLI may be used for configuration, monitoring and control. It also facilitates scripting as
an entry point for integration into existing software systems. The CLI may be accessed with
a standard terminal emulation program such as HyperTerminal running on a PC.
The RS232 connector is a 9-pin sub miniature D-type with female contacts.
Note:
See the
Installation
chapter for
connector information and pin-out
.
Connecting or disconnecting cables whilst the unit is powered on can result in damage to
interface circuits.
