Communications; Setting The Ip Address; Ethernet Communications; Serial Communications - Halcro MC30 Owner's Manual

Communications

The Halcro MC series have can be controlled
and monitored via a personal computer (PC).
A serial and an Ethernet port are available for
this purpose.
Each port has two modes of operation: plain
ASCII and pseudo-binary. In ASCII mode
commands and messages are sent as plain
text. In pseudo-binary mode commands and
messages are encoded.

Setting the IP address

The IP address can be manually setup or
automatically assigned by a DHCP server on
the network, depending on the DHCP state of
the amplifier.
If DCHP is set to 'never' an IP address and
netmask must be assigned via the serial port.
If DHCP is set to 'auto' and an IP address has
been assigned manually; you must reset the
IP address to 0.0.0.0 then the DHCP sever will
assign a new address at next start up.
If DHCP is set to 'always' a new IP address will
be obtained at start up.
If an IP address is set by DHCP the easiest
way to determine the number is to use the
Halcro HRAS software. This will communicate
with any Halcro equipment on the network via
UDP and report the IP addresses found. For
more information on HRAS software please
see page 31.

Ethernet communications

The multi-channel
connected to an Ethernet network. There are
three modes of communication
operate on different ports:
•
port 60001 is Pseudo-binary on TCP/IP
•
port 60002 is ASCII on TCP/IP
•
port 60003 is UDP/IP
HyperTerminal can be used to communicate
with a multi-channel power amplifier.
The commands are the same as for the serial
communications.

Serial communications

Almost any terminal program can be used on
a PC to communicate with a multi-channel
power amplifier. Windows provides a tool
called HyperTerminal, which can be used for
this purpose.
The settings for serial communications are:
Speed: 38400 bps
Data bits: 8
Parity: None
Stop bits: 1
Flow control: Hardware
When first connected to the amplifier via the
serial port, communications are in pseudo-
binary mode.
