9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04]
CS (DO2 Configuration) Command
CT (Time before Exit AT Command Mode) Parameter
DB (Receive Signal Strength) Command
DT (Destination Address) Command
<AT Command: Serial Interfacing> CS Command
is used to modify the behavior of the CTS signal
such that it either provides RS-232 flow control,
enables RS-485 transmission / reception or deter-
mines RS-422 transmit enable. By default, CTS
provides RS-232 flow control. CS Parameter must
be adjusted for the modem to operate in RS-485/
422 environments.
<Non-AT Settable Parameter: AT Command Options> AT Command Mode can be exited manually
using CN (Exit AT Command Mode) Command or, after a given time of inactivity, the modem exits
AT Command Mode on its own and return to Idle Mode. CT Command sets the amount of time
before AT Command Mode is exited automatically. If no characters are received before this time
elapses, the modem will return to Idle Mode.
Parameter Range: 0x02 - 0xFFFF [x 100 ms]
# of bytes returned: 2
Default Parameter Value: 0xC8 (200d (20 decimal seconds))
<AT Command: Diagnostic> DB Parameter returns the receive signal strength (in decibels) of the
last received packet. This Parameter is useful in determining range characteristics of the XCite
Modules under various conditions.
AT Command: DB
Parameter Range: 0x25 - 0x6A [Read-only]
# of bytes returned: 1
<AT Command: Networking> DT Command is used to set the address of the XCite Radio Modem.
XCite Radio Modems use three network layers - the Vendor Identification Number (ATID), Chan-
nels (ATHP) and Destination Addresses (ATDT).
DT Command assigns an address to a radio modem that enables it to communicate only with radio
modems that have matching addresses. This is similar to interconnecting several PCs under a
common hub. All radio modems that share the same destination address can communicate freely
with each other. Radio 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: DT
Parameter Range: 0 - 0xFFFF
