Wire Replacement I/O (900 MHz): User Manual and Reference Guide
DTR Connect
Setting
Description
Options:
l
(0) Off - When set to off in the Slave, the radio transmits when the data is
received.
l
(1) DTR Sensing - Forms a Point-to-Point link with the I/O Master when
the DTR line is high to send data.
l
(2) Burst Mode - The radio transmits data in bursts.
Terminal Menu:
(5) MultiPoint parameters > (4) DTR Connect
Description:
l
Determines how the radio sends its data.
l
This mode is valuable when a network has many low data rate devices
and you want to increase overall network capacity.
l
If
DTR Connect
is set to
1
and the
RTS to CTS
function is enabled on
the radio, then
RTS to CTS
takes precedence over
DTR Connect
.
l
If
DTR Connect
is set to
2
and
RTS to CTS
is enabled, then
RTS to
CTS
is ignored.
l
The radio has two separate transmit and receive user data buffers.
l
These buffers are 2 Kbytes each. In case of a buffer overflow, the radio
outputs unpredictable data.

Terminal Menu:
(5) Edit MultiPoint Parameters > (2) Max Slave Retry
Description:
l
Defines how many times the I/O Slave attempts to retransmit a packet to
