Selected output mode will be activated at next reset or power up.

Example:

smode poll

Serial mode : POLL

Set Serial Line Settings

Use the SERI command to set the serial line settings. The new settings

will be taken into use when the transmitter is reset or powered up.

Note that changing the serial line settings will slightly alter how the

transmitter works with the MI70 indicator. If you are not using the

default settings of 19200 N 8 1, you will have to power off the MI70

before it can find the transmitter (you will not be able to connect it on-

the-fly).

When using the Modbus protocol, the baud rate must be 9600 or higher.

SERI [b p d s]
where
b = baud rate (300, 600, 1200, 2400, 4800, 9600, or 19200)

p = parity (n = none, e = even, o = odd)

d = data bits (7 or 8)

s = stop bits (1 or 2)

Example:

seri 9600 e 7 1

Baud P D S : 9600 E 7 1

Set Transmitter Address

To operate in the POLL mode, the transmitter must have an address. If

multiple transmitters share the same serial line, each transmitter must

have a different address.

For a description of the serial interface modes, see section Set Serial Line

Operating Mode on page 47.

ADDR [address]

where
address

= Transmitter address, range 0 ... 255.
