RS‐232/485 RF Modem Product Manual – MAN0782‐02 
CS (GP01 Configuration) Command
DB (Received Signal Strength) Command
DT (Destination Address) Command
E0 (Echo Off) Command
 
<Serial Interfacing> CS Command is used to
select the behavior of the GP01 pin. This output
can provide RS-232 flow control, control the TX
enable signal (for RS-485 or RS-422 operations),
or set the default level for the I/O line passing
function.
By default, GP01 provides RS-232
Send) flow control.
<Diagnostics> DB Command is used to read the
receive signal strength (in decibels relative to
milliWatts) of the last received packet. This
parameter is useful in determining range
characteristics of RS-232/485 Modems under
various conditions.
In default mode, this command shows the power
level in signed decimal format, with the units
(dBm). If CF is set to 1, the magnitude of the value is presented in unsigned hex. If CF is set to
2, the value is presented in decimal, but without the units.
Sample Output:
<Networking & Security> DT Command is used
to set/read the networking address of the RS-
232/485 Modem. RS-232/485 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.
<Command Mode Options> E0 Command turns
off character echo in AT Command Mode. By
default, echo is off.
