FS (Forced Synch Time) Command

<RF Interfacing> FS Command only applies to

streaming data. Normally, only the first packet of

a continuous stream has the full RF initializer. The

modems then remain synchronized for subsequent

packets of the stream. This parameter can be

used to periodically force an RF initializer during

such streaming. Any break in UART character reception long enough to drain the DI Buffer (UART

receive buffer) and cause a pause in RF data transmission will also cause an RF initializer to be

inserted on the next transmission.

AT Command: ATFS

Binary Command: 0x3E (62 decimal)

Parameter Range: 0 – 0xFFFF

[x 10 milliseconds]

Default Parameter Value: 0

Number of bytes returned: 2

FT (Flow Control Threshold) Command

AT Command: ATFT

Binary Command: 0x24 (36 decimal)

Parameter Range: 0 – (Receive buffer size

minus 0x11 bytes)

Default Parameter Value: DO Buffer size

minus 0x11 (decimal 17)

Number of bytes returned: 2

<Serial Interfacing> Set/Read the flow control

threshold. When FT bytes have accumulated in

the DI buffer,

is de-asserted or the XOFF

software flow control character is transmitted.

GD (Receive Good Count) Command

<Diagnostics> Set/Read the count of good

received RF packets. Parameter value is reset to 0

after every reset and is not non-volatile (Value

does not persist in the modem’s memory after a

power-up sequence). Once the “Receive Good

Count” reaches its maximum value (up to

0xFFFF), it remains at its maximum count value

until the maximum count value is manually changed or the modem is reset.

AT Command: ATGD

Binary Command: 0x10 (16 decimal)

Parameter Range: 0 – 0xFFFF

Default Parameter Value: 0

Number of bytes returned: 2

Related Commands: ER (Receive Error Count)

The GD parameter is not reset by pin, serial port or cyclic sleep modes.

HP (Hopping Channel) Command

<Networking & Security> HP Command is used to

set/read the modem’s hopping channel number. A

channel is one of three layers of addressing

available to the XTend Modem.

In order for modems to communicate with each

other, the modems must have the same channel

number since each channel uses a different

hopping sequence. Different channels can be used to prevent modems in one network from

listening to transmissions of another.

AT Command: ATHP

Binary Command: 0x11 (17 decimal)

Parameter Range: 0 – 9

Default Parameter Value: 0

Number of bytes returned: 1

Related Commands: ID (Modem VID), DT

(Destination Address), MK (Address Mask)
