2. USE OF THE SERIAL ‐ BASED REMOTE PRODUCT MANAGEMENT INTERFACE IS RECOMMENDED ONLY FOR ADVANCED
USERS. ALL OTHER USERS ARE STRONGLY ENCOURAGED TO USE THE CDM ‐ 800 WEB SERVER INTERFACE FOR MONITOR
AND CONTROL (M&C) OF THE CDM ‐ 800. SEE CHAPTER 5. ETHERNET ‐ BASED REMOTE PRODUCT MANAGEMENT.
Figure 5-1. CDM-800 Serial Interface Example
CDM ‐ 800 Serial Remote Product Management is available through the EIA ‐ 232 operational interface, where the ‘Controller’ device (the
user PC or an ASCII dumb terminal) is connected directly to the ‘Target’ device (the CDM ‐ 800 Gateway Router, via its DB ‐ 9M ‘CONSOLE’
port). This connection makes possible serial remote monitor and control (M&C) of the CDM ‐ 800 through its Serial Command Line
Interface (CLI).
Through this EIA ‐ 232 connection (for the control of a single device), data is transmitted in asynchronous serial form, using ASCII characters.
Control and status information is transmitted in packets of variable length in accordance with the structure and protocol defined later in
this chapter.
Access to the CLI is accomplished with a user ‐ supplied terminal emulator program such as Tera Term or HyperTerminal. Use this utility
program to first configure serial port communication and terminal display operation:
•
38400 bps (Baud Rate)
•
8 Data Bits
•
1 Stop Bit
•
Parity = NO
•
Port Flow Control = NONE
•
