Wire Replacement I/O (900 MHz): User Manual and Reference Guide
Use Break to Access Setup
Setting
Description
l
(1) - Enabled - The Setup menu is set at 19200 bps.
l
(2) - Enabled - The Setup menu is set at the radio's current baud rate.
l
This setting is only available through the terminal interface.
Terminal Menu:
(2) Set Baud Rate > (G) Use break to access setup
Description:
l
Enables a break command to put the radio into Setup mode over the data
port.
l
To send a break character the end device must hold the Tx data line in the
space voltage level for longer than 1 character time.
Example
: If a character is defined as having 1 start bit, 8 data bits, and
1 stop bit, the character time is 10 bits, thus the Tx data line must be
held in the space voltage level for a period of time longer than 10 bits.
2.5 Establishing Communication with I/O Slaves
For the I/O Master to communicate with the I/O Slaves, it needs to know what other devices are
available for it to communicate with.
Important!
: On an I/O Master, set both the
Call Book
and
the
Network ID
to establish
communication with the I/O Slaves.
Setting both the
Call Book
and the
Network ID
is unique to wire replacement I/O and MUST be done
for both integrated and standalone applications.
l
In the I/O Master's
Call Book
tab, enter the serial number for each I/O Slave in the
network, up to a maximum of four radios.
l
The
Repeater
columns must be left blank because Repeaters are not used in a wire
replacement I/O network.
l
In the
I/O Master's MultiPoint Parameters
tab, enter an ID in the
Network ID
field that
meets these guidelines.
l
The value can be any value between 0 and 4095, except 255.
l
Avoid using numbers that coincide with nearby landmarks or highways.
FreeWave Recommends
: Use an ID of four characters.
Example
: Use the last four digits of the I/O Master's serial number. This ensures the number is
unique and does not overlap with other nearby FreeWave networks.
