Verify that the Protocol Converter is powered up and

running. You will see lights on the RJ45 (Ethernet) port

illuminated and flashing. If no lights are illuminated on

the unit, check for power to the unit. If lights are

illuminated and flashing, go to step

Connect a serial cable up to the Protocol Converter

console port. Once connect and your terminal emulation

program is running, type ip and then press enter, this will

display the current IP address set to the unit. Verify it is

the correct address. The same can be done for viewing

the Net Mask number by entering nm and then press

enter. For viewing the Default Gateway type dg and then

press enter. Correct any information that is wrong. If the

information is correct, go to step

With the serial cable connected and your terminal

emulation program open, you can enter an address to

have the Protocol Converter ping to. Get a known good

address and the type ping ip address and

then press enter. Example: ping 192.168.1.1, if a ping

response is not established, get with the IT department

and make sure the patch cord being used is good, and

then have the network switch port checked to make sure

it is activated. If a ping response is established, call your

local sales representative or RLE Technologies

technical support department.

Slave units are showing loss

of communication.

Check the Device Configuration in the Protocol

Converter and make sure the proper addressing is

assigned.

Modbus-RTU/485: The device address is set to the

proper RTU address and the 485 communications

line is wired properly.

Modbus TCP/IP: The Proper device address and IP

address has been assigned. Modbus TCP/IP

communications requires port 502 of that IP address

to be enabled/open. Check with IT to make sure there

is not a firewall or port blocking on port 502.

SNMP: Check the IP address and community that

was configured on the Protocol Converter for

communication. Port 161 of the IP address is used for

SNMP get data. Check to make sure this port is open.

BACnet: Check the IP address and device number

configured on the Protocol Converter. The default port

used for BACnet data is port 47808. Check with IT to

make sure this port is open for communication on the

network.
