COM1000 Setup and Configuration using AT Commands
To make setup and configuration easy, the COM1000 provides a common AT Command interface. This
means the device is easily configured using any Telnet or Terminal application, such as HyperTerminal, Tera
Term, or similar communications programs. This interface is also available via Telnet on TCP port 6123.
Connection Steps
Step 1: Connect your PC to the COM1000
Terminal Port
using a standard RS232
serial cable. The COM1000 Terminal Port
is a DCE port, so there is no need for a
null adapter or crossover cable. A
standard serial cable should work fine.
Step 2: Open a connection using any Terminal
program, such as HyperTerminal or Tera
Term. The default setup for the Terminal
Port is 115200, 8, None, and 1.
NOTE: You may find it necessary to configure the Terminal Port of the COM1000 to meet certain
parameters of your PC, such as a lower baud rate, or different parity, etc. If so, please refer to
the RS232/Terminal Port section of the attached Command Appendix. You must also press the
RESET button on the COM1000 in order for any serial port changes to take effect.
Step 3: Once connected, hit the ENTER key. You should see the COM1000 respond with a
command prompt that looks like the one shown here. If the COM1000 does not respond with
a command prompt, it is likely in Protected Mode, which means you will need a password to
gain access. (Refer to SECURITY section for more details)
Step 4: Once you have successfully gained access to the command prompt, you can view or edit any
of the COM1000 application registers. To view ALL the current register settings, use the AT
command AT&V. To see just a portion of the registers, type AT&V followed by the number of
the portion you wish to view. Example: to view the GENERAL section, type AT&V 1.
The AT Command for each parameter is described in detail in a later section.
