PTB150-MAN-V14.0
PTB 150-157 Instruction Manual
10.3 - Communication Protocol Rs232/C
General characteristics:
Baud Rate:
9600
Parity:
No
N. Bit:
8
Bit of stop:
1
The communication runs in half duplex way which means that is transmission and reception could not be
contemporaneously present.
The regulator replies only after receiving command; it never replies itself.
The command and reply are ASCII character string, as detailed forward. The communication program will be
able to convert ASCII to decimal to extract numeric values. The default address is 1.
Baud rate: 2400, 4800, 9600 e 19200 baud, the Default value is 9600; the other parameters are standard.
