PROCEDURE
Connecting a VT100 Terminal to the MX2820 Shelf
1. Set the parameters for the VT100 terminal as follows:
• 9600 baud rate
• 8 data bits
• No parity
•1 stop bit
• No flow control
2. If the terminal has a parallel setting, disable it, and use the serial setting.
3. Plug the male end of the serial data cable into the craft port (DB-9 connector) on the SCU
front panel.
4. Make the data cable connection to the VT100 terminal as appropriate for the equipment.
Connecting a PC emulating a VT100 Terminal to the MX2820 Shelf
Most Personal Computers (PC) or laptops can run communications software that emulates a
VT100 terminal. Windows programs such as Terminal or Hyperterminal, are two examples,
but there are other commercially available software packages which allows a PC or laptop to
emulate a VT100 terminal. There are configuration items that must be set on a PC or laptop
before they can emulate a VT100 terminal for the MX2820 system.
1. Set the parameters of the communications software as follows:
• 9600 baud rate
• 8 data bits
• No parity
•1 stop bit
• No flow control
2. Set the PC for direct connect on the appropriate com port.
3. Plug the male end of the serial data cable into the craft port (DB-9 connector) on the SCU
front panel.
4. Make the data cable connection to the PC or laptop as appropriate for the equipment.
