Configuring the RF Communications
Section 5
In order for the Base Radio and the Field Unit to communicate they must
be on the same RF Channel, and must be transmitting at the same Baud
Rate. While all Field Units and Base Radios are set to default configura-
tions at the factory, if any configuration differences are present the Base
Radio will not be able to communicate to the Field Units. The subsections
are as follows:
5.1: RF Channel Selection
5.2: RF Baud Rate Selection
5.1: RF Channel Selection
All Base Radios and Field Units can be set to one of 16 different commu-
nication channels. The only Field Units recognized by a particular Base
Radio are the units that share the same RF Channel as that Base Radio.
This allows the user to decide which Field Units communicate with each
Base Radio.
Each Base Radio comes from the factory set to the RF OFF channel. This
means the Base Radio will not communicate with any Field Units. To set
the Base Radio for communication first determine the channel that you
wish to use, then follow the Base Radio menu map shown below in Figure
5.1 to configure the RF Channel.
Figure 5.1: Menu Map to RF Channel Setting
5.2: Baud Rate Selection
The RF Baud Rate refers to the speed at which the Base Radio and Field
Units communicate. There are three selectable settings with approximate
update times and ranges listed below:
•
4.8K- Baud rate of 4.8 Kbaud (Update every 20 seconds)
- Range of 3000ft (Line of Sight)
•
19.2K- Baud rate of 19.2 Kbaud (Update every 5 seconds)
- Range of 2000ft to 2500ft (Line of Sight)
•
76.8K- Baud rate of 76.8 Kbaud (Update every 1 second)
- Range of 500ft to 750ft (Line of Sight)
A faster RF Baud Rate will allow you to transmit more information in a
certain period of time, but it will also limit your range. If you need more
distance out of your Field Units or are encountering difficulties by fre-
quently losing communications, then select a slower baud rate.
Follow the Base Radio menu map shown in Figure 5.2 to configure the RF
Baud Rate. The factory default is the 19.2K Baud Rate.
Once you are in the RF Channel menu, you can increment it by pressing
the NEXT button. When selecting this value, do not choose an RF Chan-
nel that is currently being used by other Accutech Wireless Systems as this
can cause communication problems.

NOTE
If you change the baud rate of the Base Radio, you
must also change the baud rate of all other Field
Units that are communicating with that Base Ra-
dio to match.
Caution
If the Base Radio is not energized for more than
30 minutes, the Field Units should also be turned
off to preserve battery life. Leaving the Field
Units on when the Base Radio is not energized or
out of range will cause the Field Units to transmit
very frequently and drastically reduces their bat-
tery life.
