Operating the User Port (RS-485)

The RS-485 interface enables communication between RS-485 network

and HMT130 transmitter. The RS-485 interface is not isolated.

Networking Commands

Set the RS-485 interface by using the following commands. The other

serial line commands are presented in section List of Serial Commands

on page 30.

SERI

Use the SERI command to input RS-485 bus settings. This command

affects the serial port where the settings are given (service port or user

port).

SERI [b p d s]<cr>

where

= bit rate (1200, 2400, 4800, 9600, 19200, 38400, 57600,

115200)

= parity (n = none, e = even, o = odd)

= data bits (7 or 8)

= stop bits (1 or 2)

SERI2

The SERI2 command is equivalent to the SERI command, but it affects

only the user port settings. The main purpose of the command is to

change the user port settings via the service port.

SERI2 [b p d s]<cr>

1 2 ... 47 48 49 50 51 52 53 54 55 56 57 ... 95 96
