Protocols
The DS Series encoder inside the Long-Range Handheld transmitter
supports two protocols. The first protocol is based on the Holtek HT640
encoder and is completely backwards compatible with older generation
transmitters and systems based on the HT658 decoder. The second is a
serial protocol that offers more noise immunity and faster response time
while keeping the simple addressing.
The transmitter can use only one protocol at a time. The protocols do not
Setting the Transmitter Address
The Long-Range Handheld transmitter
allows the selection of one of 1,022
unique addresses. All transmitters are
supplied set to the same address. To
avoid contention with other units or to
create unique relationships, the address
can be changed. This is accomplished
using internal DIP switches as shown. The
work together.
The protocol is selected with a switch next to the battery. Figure 5 shows
this switch.
switches are accessed by removing the
DIP switch access cover on the back of
the transmitter.
If the switch is on, the address line is
connected to ground, otherwise it is pulled
to supply. The receiver’s address must
A0 = 1
A1 = 2
A2 = 3
A3 = 4
A4 = 5
A5 = 6
A6 = 7
A7 = 8
A8 = 9
A9 = 10

match exactly in order for the units to
communicate. Application Note AN-00300
describes in detail how to set the address Figure 6: DIP Switch Assignments
to match any of the receivers offered by Linx. This note can be found in the
Support section of the Linx website, www.linxtechnologies.com.
Note: Setting all of the DIP switches on or all of them off are not valid
addresses. At least one switch must be different from the rest.
Figure 5: Protocol Selection Switch
If the switch is toward the top then the Holtek protocol is selected. If the
switch is toward the bottom then the serial protocol is selected.
