Data rates and sensitivity
The following table lists XLR PRO available data rates along with the corresponding receiver sensitivity.
Power supply
The XLR PRO must be powered by a UL-listed power supply rated between 9 and 26V DC. Refer to the following table
for the required input current settings.
Operational modes
XLR PRO offers three operational modes:
•
Serial (RS-232/RS-485):
In serial mode, the front panel serial port provides connectivity to the XLR PRO via RS-
232 or RS-485/422.
•
Ethernet (IP socket):
In IP socket mode, an XLR PRO can transmit and receive serial data via a TCP or UDP
connection from either of the front panel Ethernet ports.
•
Ethernet RF Bridging:
In Ethernet RF bridging mode, an XLR PRO functions as an Ethernet cable replacement,
supporting point-to-multi-point transmission for a maximum of 16 XLR PRO RF modems. By default, bridging
mode is disabled. Serial data from serial or IP socket mode operates concurrently with Ethernet RF Bridging. If
serial and Ethernet traffic are sent at the same time, there will be some latency.
