DA_Out
GND
This probe point provides a location for measuring the DA_Out pin (pin 19).
This probe point provides a GND reference location.
When this Switch is moved to the Program Mode position, the RTS pin from the
DB9/USB connector is connected to the Command/Data pin (AC4490,
AC4486, AC4424, AC4790, AC4868), the TE pin (AC3124, AC1524) and the
Pktmode pin (AC5124) of the transceiver. RTS of the transceiver is also
connected to GND. This allows the SDK software to control these pins with
RTS always enabled.
When the Switch is moved to the Normal position, RTS at the DB9/USB
connector is connected to RTS pin of the transceiver and Command/Data is left
disconnected.
The AC4424, AC4490, AC4790, AC4486 and AC4868 families all support AT
Commands for making changes to the EEPROM settings. If the “Read/Write
with AT Commands” checkbox is enabled on the PC Settings page of the
configuration software, then the Program/Normal switch can always be set to
Normal. The AC5124 family also supports AT Commands when that function is
enabled in the transceiver EEPROM.
When this pushbutton is pressed, the transceiver hardware performs a soft
reset.
When this pushbutton is pressed, it will take the Write Enable pin (AC4424,
AC5124, AC3124, AC1524) or GI1 pin (AC4490, AC4486, AC4790, AC4868)
Low. This button must be pressed and held during the write process for
AC5124, AC3124, AC1524, and AC4424 product families.
If using a transceiver module fitted with a RS-485 interface chip, RS485 Radio
should be selected. This converts the transceiver’s RS-485 interface to serial,
which is then converted to the interface selected by the COMM SELECT
jumper.
If not using a transceiver module fitted with a RS-485 interface chip, TTL Radio
should be selected.
When this jumper is moved to the RS232 Enable position, RS-232
communication is enabled through the DB9 connector (J2).
When this jumper is moved to the RS485 Enable position, RS-485
communication is enabled through the RS-485 header pins.
When this jumper is moved to the Loopback Mode position, the transceiver
TxD pin is tied to the transceiver RxD pin. This is only valid for AC5124,
AC4424 and AC4486, AC4490, AC4790, AC4868 products. RTS mode must
be disabled on the transceiver when Loopback Mode is enabled. This mode is
not compatible with RS485 Radio selection.
