Notes:

• For Model 1700/2700, Model 2400S, and LF-Series field-mount transmitters, the service port is available at any

time.

• For Model 1500/2500, Series 3000, and LF-Series DIN rail transmitters, the service port is available during a

10-second interval after power-up. If a service port connection is made during this time, the ports will remain in

service port mode.

• Ensure that no other Modbus master devices are currently active on the network.

• All service ports are accessed using the default address of 111. If you are connecting over a multidrop network

with multiple service ports, it is not possible to specify which device to connect to.
