Introduction
Data-Linc Group (DLG) has prepared this user guide for use by customers as a guide to the proper installation, operation,
and maintenance of a Wireless I/O Extender system. This includes the following DLG products:
DDAA1000 - Discrete and Analog Wireless I/O Extender (1 Watt, 900 MHz FHSS)
DD1000 - Discrete Wireless I/O Extender (1 Watt, 900 MHz FHSS)
DDAA1000/2.4 - Discrete and Analog Wireless I/O Extender (500mW, 2.4 GHz FHSS)
DD1000/2.4 - Discrete Wireless I/O Extender (500mW, 2.4 GHz FHSS)
PLR580DA - Discrete and Analog Wireless I/O Extender (200mW, 900 MHz FHSS)
PLR580D - Discrete Wireless I/O Extender (200mW, 900 MHz FHSS)
The Discrete Wireless I/O Extender is a discrete signal multiplexer and the Discrete and Analog Wireless I/O Extender is
a discrete and analog signal multiplexer. They are designed to provide wireless communication where wire lengths are
too long, too costly or not possible. In general, these units behave as if they replace a set of wires between the two or
more locations. These units are normally factory congured and eliminate the necessity of having to congure the units
in the eld. The units are ready for installation into the system upon receipt. If the system changes, these units do have
the capability to be eld recongured and to have access to the radio setup parameters using dipswitch settings and a 9
pin din serial cable to a PC. The units are congured using windows software or a terminal emulation program such as
Hyperterminal©.
The analog models have both analog and discrete inputs and outputs. The unit has 8 analog input channels, 8 analog
output channels, 8 discrete inputs, and 8 discrete outputs. The analog channels are 4-20 mA inputs and outputs with 8 bit
resolution, and the discrete inputs are a contact closure with relay drive outputs.
The discrete models have only discrete inputs and outputs. The unit has 8 discrete contact closure inputs and 8 relay
drive outputs. When designing a system that uses these units, keep in mind that if using more than one remote (8 pos-
sible) that the master unit can never have more that 8 digital-in, 8 digital-out, 8 analog-in, and 8 analog-out.
The Wireless I/O Extender takes an input at one end and reproduces it at the other end as an output. The units with I/O
Congure V2.0 are Master or Remote selectable. Older versions are master and remote specic. Each system must have
one master and at least one remote, but can have up to 8 Remotes.
Communication is accomplished using radio transceivers. A six-inch unity gain whip antenna is supplied with each unit for
test purposes.
Note: These transceivers are “line of sight” transceivers, so line of sight is required for communications. In some
instances, depending on distance and obstruction, line of sight may not be necessary, but high latency or poor
communications could result. If line of sight does not exist or the units are to be mounted into grounded metal
enclosures, an external antenna may be needed. If external antennas were not purchased with this equipment,
contact Data-Linc Group for information.
