Baud Rate: 2400, 4800, 9600, 19200, 38400, 57600, or 115200 selectable
Data Format:: IEEE floating point and 32-bit integer. Word swap configurable.
Length of Link:
2000 ft (600 m) max. with Belden 9271 Twinax Cable and 120 ohm termination resistors
4000 ft (1200 m) max. with Belden 8227 Twinax Cable and 100 ohm termination resistors
Link Characteristics: Two-wire (half-duplex), multi-drop Modbus RTU protocol, 15 drops maximum or
up to 31 drops for shorter link length.
Modbus RTU slave: Provides monitoring of inputs outputs, statuses, alarms, and variables. Provides
writing of variables for remotely modifying parameter settings.
Type: 10 or 100 BaseT; auto-speed and auto-polarity sensing
Length of Link: 330 ft. (100 m) maximum. Use Shielded twisted-pair, Category 5 (STP CAT5) Ethernet
cable.
Link Characteristics: Four-wire plus shield, single drop, five hops maximum
IP Address: IP Address is 192.168.1.254 as shipped from the factory
Recommended network configuration: Use Switch rather than Hub in order to maximize UDA Ethernet
performance
Configuration: Ethernet parameters are configured via the front-panel or web pages.
Modbus TCP/IP: Five simultaneous socket connections provide monitoring of inputs outputs, statuses,
alarms, and variables. Provides writing of variables for remotely modifying parameter settings.
Modbus TCP/IP Data Format: IEEE floating point and 32-bit integer. Word swap configurable.
Web server: multiple client support
Web pages: monitoring inputs, outputs, statuses, alarms, and events
Multi-language Email: Alarm notification to eight email addresses. These must be configured using
web pages signed in as the administrator.
DHCP: ( Dynamic Host Configuration Protocol) selectable via web page or front-panel
