3.4 Remote Control Using Terminal Mode
This mode allows the MA4040D to be controlled using a standard terminal (or terminal emulation) program. In
order to use this mode, the following information is required:
•
Terminal mode must be selected from the front panel on the power supply. 1) Press the Module Select button until Module
K is selected. 2) Press the Mode button until the Remote Interface type is selected (RS-232, RS-485). 3) Press Up or
Down until Terminl Selected is displayed on the screen.
•
The MA4011D does not provide a prompt and will only send a response when a command has been received.
•
Local Echo should be enabled for the terminal (the Communications/Control Module will not echo the characters). (NOTE:
If Windows 98 is being used, the local echo feature in Hyperterminal may not work. This issue is documented in the
Microsoft Knowledgebase. For more information send an e-mail to [e-mail] with Q192456 in the subject
line).
•
The terminal type can be TTY or VT100 or similar.
•
CR -> CR/LF mapping should be disabled for both inbound and outbound traffic
•
The only special characters that are implemented are carriage return (0x0D, ^M), linefeed (0x0A, ^J), and destructive
backspace (0x08, ^H). All other characters are processed as part of the message.
The command syntax is as shown in Section 7.0,Remote Control (pp 27 to 34) with the following modifications:
•
Commands should not have an initial asterisk
•
The CRC ignored
•
The maximum message length is 49 characters
•
All commands are parsed from left to right. Only the first command on a line is processed, any additional characters are
ignored
3.5 Remote Control Using Terminal Mode over a standard phone modem
It is possible to use the terminal mode to remote control the MA4000 system over a modem connection. The
information in Section 3.4, Remote Control Using Terminal Mode (p 17) still applies to this configuration; however,
there are two additional requirements:
1) The modem that is connected to the MA4002D chassis MUST be configured so that it's serial port (DTE) is
locked at 9600 baud. Additional settings are hardware flow control (RTS/CTS), 8N1 data, auto-answer, no dial-
out.
2) There are no special requirements for the modem that is connected to the PC used for remote control.
Note: This was tested with a US Robotics Sportster 33.6 external fax modem. Other modems in the US Robotics
Courier or Sportster lines will also work. A set of general configuration instructions for a US Robotics Courier or
Sportster modem can be found at:http://www.usr.com/modem/documents/10563.htm
Modems other than the specific ones mentioned may not support this configuration. If in doubt, consult with your
modem vendor.
