Using ‘AT’ Commands
The PRC1000 AT Commands are a format similar to traditional Hayes-Compatible AT Commands, but
because the device is not a modem, the similarities are modest. In order to configure the device using AT
Commands, follow these directions:
Step 1: Connect your PC to the PRC1000 RS232 interface
using a standard RS232 cable. The PRC1000
interface is a DCE port, so a standard serial cable
is all you need..
Step 2: Open a connection using any Terminal program,
such as HyperTerminal or TeraTerm. The default
setup for the port is 9600, 8, None, and 1.
Step 3: Once connected, your should hit the RETURN or
ENTER key. That will bring up the device command prompt.
Step 4: Once you have successfully gained access to the command prompt, you can view or edit any
of the PRC1000 application registers. To view ALL the current register settings, use the AT
command AT&V.
