Seamless mode (BUFF ON) is intended only for applications where the
message size is 256 characters or less. Enforcement of this rule is left up to
the user. If more than 256 characters are transmitted data delivery will not be
seamless and data may be lost.
Changes to the BUFF setting may only be made at the Master radio. This is
because the Master radio broadcasts the buffer setting for the entire network.
At Remote radios, the buffer setting may be read when the radio is in synchro-
nization with the Master, but it cannot be changed.
CODE [NONE, 1…255]
Security Code
The CODE command is used to select or display the security/encryption
setting in the radio.
The default is CODE NONE. Setting CODE to a value other than NONE
provides an extra level of security beyond that provided by the Network
Address (ADDR). The disadvantage is increased complexity in managing the
network.
The CODE command takes an argument 1…255, or NONE. Entering CODE
without an argument will display either NONE or ACTIVE. ACTIVE means
that security/encryption has been enabled, but the radio will not display the
security argument.
When a CODE value is active, all radios in the system must use the same code
value. If the code value is not properly programmed, a Remote radio will not
synchronize with the Master.
CAUTION: Record the CODE value and store it in a safe place. If the code is
later forgotten, and a unit is to be added to the system, all radios in the
network must be set to NONE and then reprogrammed to a new value.
CSADDR [1–65000, NONE]
Clock-Synchronizing Master Address
Used to specify the network address of a “Clock-Sync” Master station to
which this station will be synchronized. Also see “ADDR [1–65000]” on
Page 29 and “Co-Located and Close-Proximity Masters” on Page 63 for
further details.
CTS [0–255]
Clear-to-Send Delay
The CTS (clear-to-send) command sets or displays the timer value associated
with the CTS line response. The command parameter ranges from 0 to 255
milliseconds.
For DCE operation, the timer specifies how long to wait after the RTS line
goes high before asserting the CTS line. A timer value of zero means that the
CTS line will be asserted immediately following the assertion of RTS.
