Service port:
• Can be used for temporary connection only
• Uses RS-485 Modbus signal, 38.4 kilobaud, one stop bit, no parity
✓ ✓ ✓ ✓ ✓
HART/RS-485, Modbus/RS-485:
• One RS-485 output can be used for direct connection to a HART or Modbus
host system; accepts data rates between 1200 baud and 38.4 kilobaud
• HART revision 5 as default, selectable to HART revision 7
✓
HART/Bell 202:
• HART Bell 202 signal is superimposed on the primary milliamp output, and
is available for host system interface. Frequency 1.2 and 2.2 kHz, Ampli-
tude: to 1.0 mA, 1200 baud, Requires 250 to 600 ohms load resistance
• HART revision 5 as default, selectable to HART revision 7

(4) When output option B is ordered, the channels are configured at the factory for two mA and one frequency
output; When output option C is selected, the channels are custom configured at the factory.
(5) For custody transfer using double-pulse frequency output, the transmitter can be configured for two
frequency outputs. The second output can be phase shifted –90, 0, 90, or 180 degrees from the first output,
or the dual-pulse output can be set to quadrature mode
(6) If communicating with HART a minimum of 250 ohms and 17.75 V supply is needed.
(7) Absolute minimum = 100 ohms for V
supply
< 25.6 volts.
