Setup for devices with RS232 serial interface
(option I1)
P60
Display address [11, 99]
Enter here the serial address of the readout when
using the serial interface option RS232. Don't use
addresses 20, 30, 40,….., 90.
Default value:
11
P61
Baud rate [0, 4]
0 = 2400
1 = 4800
2
= 9600
3 = 19200
4 = 38400
P62
RS232 mode [0, 3]
0
= RS232 protocol according to DIN66019
1 = Printer mode. To transmit actual value
periodically to a printer at a time interval set in
parameter
P63
.
2 = Printer mode. To transmit actual value to a
printer when pushing
E
button (attention to
P07
: do not use 1, 4 and 16 functions).
3 = Printer mode. To transmit actual value to a
printer when activating Input CON3/ pin 5
(attention: set
P12
= 0).
P63
Transmission time interval [0.01, 650.00]
Enter the time interval for periodic actual value
transmission in sec. (
P62
must be =1).
Default value:
1.00
P99
Actual value for RS232 [-99999, 999999]
This parameter shows the actual value for serial
transmission via RS232 Interface if parameter
P62
=0.
NOTE:
In order to activate modified parameters, switch off
and on the device.

8.3 Communication protocol
The RS232 protocol is according to DIN 66019, ISO
1765, ANSI X3.28.
The PC is the master and the MC150 is the slave
with individual serial address to be entered in
Parameter
