Emerson 2400S User Manual

38

Service port

One service port for temporary connections (requires removing transmitter 
housing cover)

Uses RS-485 Modbus signal, 38.4 kBaud, one stop bit, no parity

Address: 111 (not configurable)

Wireless

If transmitter has display, service port can be accessed with IrDA device (for 
example, a PDA running Pocket ProLink) without removing transmitter housing 
cover. If transmitter has no display, access to service port requires removing 
transmitter housing cover.

HART/Bell 202

HART signal is superimposed on the primary milliamp output (Channel A), and is 
available for host system interface:

• Frequency: 1.2 and 2.2 kHz

• Amplitude: to 1.0 mA

• 1200 baud, one stop bit, odd parity

• Address: 0 (default), configurable

• Requires 250 to 600

Ω resistance

PROFIBUS-DP

Digital 2-way communication protocol

• Automatically recognizes network baud rate

• Address selectable by 3 rotary switches, or software selectable

DeviceNet

Digital 2-way communication protocol

• Address and baud rate selectable by 3 rotary switches (2 to select address, 1 to 

select baud rate), or software selectable
