0 40401 Password 0…9999 0 Required to change configuration data. Returns -1
1 40402 Hardware port 0…1 0 Select active port
0 = RS-232 port
1 = Native RS-485 port
2 40403 Protocol 0…3 0 Communication protocol for the native
communication port.
0 = DF1 half-duplex slave
1 = Modbus RTU slave
2 = Auto Sense - Selects the protocol based on the
incoming communication packets
3 = DF1 full-duplex
3 40404 Delay 0…15 2 (10 ms) Specifies the delay before responding to an
external request., useful with slow external
devices (such as RF modems)
4 40405 Baud rate 0… 6 3 0 = 1.2 Kbps
1 = 2.4 Kbps
2 = 4.8 Kbps
3 = 9.6 Kbps
4 = 19.2 Kbps
5 = 38.4 Kbps
6 = 57.6 Kbps
5 40406 RS-232 address 1…247
(1)
Identifies the device on the link. 0 is typically used
by the DF1 master. 255 is the broadcast address
6 40407 Data format 0…2 0 Parity, number of data bits, number of stop bits
0 = No parity, 8 data bits, 1 stop bit
1 = Even parity, 8 data bits, 1 stop bit
2 = Odd parity, 8 data bits, 1 stop bit
7 40408 Flow Control (Handshaking) 0…1 0 Data flow control for RS-232/RS-485 port.
0 = None
1 = Hardware RTS/CTS
8 40409 RTS On Delay 0…9995
ms
0
9 40410
10 40411 Inter-character timeout Specifies the minimum delay between characters
that indicates the end of a message packet. 0 = 3.5
character times.
11 40412 Error checking 0…1 0 0 = CRC
1 = BCC
