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]
where
b = bit rate (1200, 2400, 4800, 9600, 19200, 38400, 57600,
115200)
p = parity (n = none, e = even, o = odd)
d = data bits (7 or 8)
s = 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.
