RS (RSSI) Command

©2006MaxStream,Inc.ConfidentialandProprietary 34

<Diagnostics> RS Command returns the signal

level of the last packet received. This reading is

useful for determining range characteristics of the

XStream Modems under various conditions of

noise and distance.

Once the command is issued, the modem will

return a value between 0x6 and 0x36 where 0x36 represents a very strong signal level and 0x4

indicates a low signal level.

AT Command: ATRS

Binary Command: 0x1C (28 decimal)

Parameter Range: 0x06 – 0x36 [Read-only]

Number of bytes returned: 1

Minimum Firmware Version Required: 4.22

RT (DI2 Configuration) Command

AT Command: ATRT

Binary Command: 0x16 (22 decimal)

Parameter Range: 0 – 2

Parameter Configuration

0 disabled

1 Enable Binary Programming

2 Enable

Flow Control

Default Parameter Value: 0

Number of bytes returned: 1

<Serial Interfacing> RT command is used to

dictate the behavior of the DI2/

/CMD line. RT

Command must be issued to enable

flow

control or binary programming.

RZ (DI Buffer Size) Command

AT Command: ATRZ

Binary Command: 0x2C (44 decimal)

Parameter Range: Read-only

Number of bytes returned: 2

Minimum Firmware Version Required: 4.30

<Diagnostics> The RZ command is used to read

the size of the DI buffer (UART RX (Receive)).

Note: The DO buffer size can be determined by

multiplying the DI buffer size by 1.5.

SB (Stop Bits) Command

AT Command: ATSB

Binary Command: 0x36 (54 decimal)

Parameter Range: 0 – 1

Parameter Configuration

0 1 stop bits

1 2 stop bits

Default Parameter Value: 0

Number of bytes returned: 1

Minimum Firmware Version Required: 4.2B

<Serial Interfacing> SB Command is used to

set/read the number of stop bits in the data

packets.

SH (Serial Number High) Command

AT Command: ATSH

Binary Command: 0x25 (37 decimal)

Parameter Range: 0 – 0xFFFF [Read-only]

Number of bytes returned: 2

Related Commands: SL (Serial Number Low)

Minimum Firmware Version Required: 4.27C

<Diagnostics> Set/Read the serial number high

word of the modem.
