OACSU
It needs to give the radio a respond, then it will send the

13.11
RX TS
The Radiod
d
ity DB25-D and GD-88 are based on TDMA technology and can divide
a 12.5kHz channel into two alternate Time Slots.
When operating a digital repeater or duplex-hotspot with the Radiod
d
ity DB25-D
or GD-88, normally the digital repeater does have a TX-frequency different to its
RX-frequency and uses DMR Tier 2 for transmission. DMR Tier 2 makes uses of the
Time Slot technique, allowing two separate information channels to be
transmitted using the very same physical channel. Normally the Time Slots (TS) for
TX and RX must be set to the very same Time Slot, either 1 or 2.
Whereas, when operating a simplex station (such as a simplex hotspot), normally,
DMR Tier 1 is in place. DMR Tier 1 does not make use of those Time Slots.
Whenever TX and TX-frequency are identical (which is the case in simplex mode),
a third option
‘On’ (for direct simplex mode) becomes
available for such channel.
Options
: Slot 1 Use DMR Tier 2, Time Slot 1 for RX
Slot 2 Use DMR Tier 2, Time Slot 2 for RX
On
Use DMR Tier 1 for RX without any Time Slots
Default: On
Notes:
This parameter is only available in digital mode.
13.12
TX TS
The use of this parameter is identical to
‘
RX T
S’
, except that it refers to transmit
mode of the DB25-D.
Options
: Slot 1 Use DMR Tier 2, Time Slot 1 for TX
Slot 2 Use DMR Tier 2, Time Slot 2 for TX
On
Use DMR Tier 1 for TX without any Time Slots
Default: On
Notes:
This parameter is only available in digital mode.
