DR (DI3 Configuration) Command

AT Command: ATDR

Binary Command: 0x2D (45 decimal)

Parameter Range: 0 – 4

Parameter Configuration

0 Disabled

1 DI3 I/O passing enabled

2 Connect on low

3 Disconnect on high

4 Connect and Disconnect

Default Parameter Value: 0

Number of bytes returned: 1

Related Commands: CD (DO3 Configuration),

CO (DO3 Timeout), MD (RF Mode)

Minimum Firmware Version Required: 4.30

<Serial Interfacing> The DR Command is used to

configure the DI3 (Data Input 3 / SLEEP) line for

I/O line passing (use with CD = 1 or 2 and CO)

or controlling connection status (use with MD = 1

or 2).

DT (Destination Address) Command

<Networking> DT Command is used to set the

networking address of an XStream Modem.

XStream Modems uses three network layers –

Vendor Identification Number (ATID), Channels

(ATHP), and Destination Addresses (ATDT). DT

Command assigns an address to a modem that

enables it to communicate only with other

modems having the same addresses. All modems

that share the same Destination Address can

communicate freely with each other. Modems in the same network with a different Destination

Address (than that of the transmitter) will listen to all transmissions to stay synchronized, but will

not send any of the data out their serial ports.

AT Command: ATDT

Binary Command: 0x00

Parameter Range: 0 – 0xFFFF

Default Parameter Value: 0

Number of bytes returned: 2

Related Commands: HP (Hopping Channel), ID

(Modem VID), MK (Address Mask)

E0 (Echo Off) Command

AT Command: ATE0

Binary Command: 0x0A (10 decimal)

<Command Mode Options> E0 Command turns

off character echo in AT Command Mode. By

default, echo is off.

E1 (Echo On) Command

AT Command: ATE1

Binary Command: 0x0B (11 decimal)

<Command Mode Options> E1 Command turns

on the echo in AT Command Mode. Each typed

character will be echoed back to the terminal

when ATE1 is active. E0 is the default.

ER (Receive Error Count) Command

<Diagnostics> Set/Read the receive-error. The

error-count records the number of packets

partially received then aborted on a reception

error. This value returns to 0 after a reset and is

not non-volatile (Value does not persist in the

modem’s memory after a power-up sequence).

Once the “Receive Error Count” reaches its

maximum value (up to 0xFFFF), it remains at its

maximum count value until the maximum count value is explicitly changed or the modem is

reset.

AT Command: ATER

Binary Command: 0x0F (15 decimal)

Parameter Range: 0 – 0xFFFF

Default Parameter Value: 0

Number of bytes returned: 2

Related Commands: GD (Receive Good Count)
