16 ADAM-4000 PROTOCOL SUPPORT
The EtherMeter is available with ADAM-4000 protocol support (Optional. ADAM-Version Only).
This portion of the manual assumes that the user is well-versed in the ADAM-4000 Protocol. In
order to learn more about the ADAM-4000 protocol, visit www.advantech.com
.
The following subset of the ADAM-4000 protocol is supported by the EtherMeter:
#AAn - Read Analog Inputs (32 bit signed hexadecimal format)
$AA6 - Read Discrete Inputs
#AA100d - Write Discrete Outputs
$AAM - Read Device ID
The checksum option is available, but turned OFF by default. Checksum may be enabled via the
Setup Menu.
To test and/or verify ADAM-4000 communications with the EtherMeter, a terminal program (such
as HyperTerminal) may be used.
The ADAM-4080D 2-Channel Pulse Counter Input Module is often used to interface to
pulse-output meter registers. As an improvement, the EtherMeter may be used as an
ADAM-compatible replacement for interfacing to encoder-output meter registers.
