46 Chapter 10 Configuring the Digi Device for IA (Industrial Automation)
• If you configure a port for a master and the slaves are located on the
network, TCP sockets, UDP sockets, and Modbus/TCP are all sup-
ported. Use the protocol required by the master.
Configuring the User-Defined Protocol
Digi One\PortServer TS 2/4 MEI devices support what Digi calls the “user-
defined” protocol, which is any IA serial-port protocol with the following
attributes:
• All message packets are bounded by fixed header and trailer
strings.
• Each protocol request is followed by a single response.
Procedure
1. Access the web interface.
2. Sign in as root. The default password is dbps.
3. Choose Setup Wizard > Industrial Protocols.
4. Use the wizard to complete configuration tasks. Here are a few tips:
• Configure the serial port for serial communication parameters (baud
rate, data bits, parity and stop bits) required by the connected IA
device.
• Choose User-defined as the serial-port protocol.
• If you configure the port for a slave, you do not have to configure a
network-based master. Communication with the master just works.
(If the master is connected to a serial port, it must be configured,
however.)
• If you configure a port for a master and the slaves are located on the
network, TCP sockets and UDP sockets are supported options.
