SX-200 ICP MX Technician’s Handbook
Preparing to Enter Customer Data
You can use a desktop or laptop computer to program the controller on-site
or from a remote location.
PC requirements
• Windows 98, NT, 2000 Professional, ME or XP
(Windows 98 does not support secure Telnet)
• for serial connections, a VT100™ emulator such as HyperTerminal
• for remote or LAN-based connections, a secure Telnet client that
supports SSL/TLS (Mitel Telnet client version 1.0.0.1 or later
recommended), or a web browser (Internet Explorer 6 or Mozilla
Firefox) to access the SX-200 ICP Web Interface
• a Network Interface Card (NIC)
The PC can connect to the controller via a serial connection to the
Maintenance port or via a secure Telnet connection to port 2000.
Serial Connection to the Controller
1. Connect an RS-232 straight DTE serial cable between the controller's
Maintenance port and the PC's serial port.
2. Program the PC's serial port (from the communication program) with
the following settings:
Baud Rate: 9600 or 19200
Stop Bits: 1
Data Bits: 8
Flow Control: None
Parity: None
3. Verify the connection as follows:
- In the VT100 emulator or other communications program, press
RETURN several times.
While the maintenance session is active, do not disconnect the serial cable
or attempt to open another maintenance session with a Telnet connection.
Doing so will cause an error message stating that CDE is currently in use.
