PRT2 can also be used as a DF1 port if the DF1 driver is enabled (using CALL
108). Refer to Using DF1 Protocol Communications for more information on
using the DF1 protocol.
Changing the Port Communication Parameters
The port communication parameters can be changed using the MODE
command:
The MVI56-BAS ports PRT1 (COM2) and PRT2 (COM3) have the following
default communication parameters:
Description Value
Baud Rate 19200
Parity N
Number of Data Bits 8
Number of Stop Bits 1
Handshaking N
In order to change a port communication parameter, you should use the MODE
function.
MODE Syntax for PRT1 (COM2) and PRT2 (COM3)
MODE(port,baud rate, parity, data bits, stop bits, handshake, storage type)
Where:
Port: PRT1, PRT2
Communication rate: 300, 600, 1200, 2400, 4800, 9600, 19200.
Parity: N (none), E (even), O (odd).
Number of data bits: 7 or 8 .
Number of Stop Bits: 1 or 2 .
Handshaking: N (no handshaking), S (software handshaking),
H (hardware handshaking), B (hardware and software handshaking)
Storage type: E (store information in user ROM and RAM) ,
R (store information in battery backed RAM)
For example, in order to change the PRT 1 communication baud rate to 9600,
the user would enter:
Ready
>MODE(PRT1,9600,N,8,1,N,R)
MODE Syntax for DH-485 (COM1) port
MODE(port, baud rate, host node address, module node address, maximum
node address, , storage type)
Where:
Port: DH485
Communication rate: 300, 600, 1200, 2400, 4800, 9600, 19200.
Host Node Address: 0 to 31
