An RJ45 Ethernet connector allows the transmitter to be connected directly to a computer, router,
switch or hub via an Ethernet cable. An isolated analog output and dual relays are also standard.
Jumpers on the main board allow selection of the following:
• Analog output (current or voltage).
• Power over Ethernet (PoE). Only available for main boards with the 10-48 Vdc power option.
Jumpers are preset if PoE is specified at the time of purchase.
• Excitation output. Note that attempting to draw more than the rated transducer excitation
output current will shut down the output.
Jumpers on analog signal conditioner boards are described in later manual sections.
To reset the transmitter (same as power-up), press the Reset button.
To reset communications to 9600 baud, command mode, Custom ASCII protocol, and Address 1,
place a jumper at E1 and power up the transmitter.
