Code [None, 1; Cts [0-255] - Microwave Data Systems MDS TransNET 900 Installation & Operation Manual

If data buffering is , the radio will operate in a seamless mode. That is, data
ON
bytes will be sent over the air as quickly as possible, but the receiver will
buffer the data until the entire packet has been collected. The delay introduced
by data buffering is variable and depends on message size and the number of
retransmissions required, but the radio will not create any gaps in the output
data stream. This mode of operation is required for protocols such as
MODBUS™ that do not allow gaps in their data transmission.
Seamless mode ( ) is intended only for applications where the
BUFF ON
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 setting may only be made at the master radio. This is
BUFF
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
synchronization with the master, but it may not be changed.

CODE [NONE, 1...255]

The command is used to select or display the security/encryption
CODE
setting in the radio.
The default is . Setting to a value other than
CODE NONE CODE NONE
provides an extra level security beyond that provided by the Network Address
( ). The disadvantage is increased complexity in managing the network.
ADDR
The command takes an argument or " ". Entering
CODE 1...255, NONE CODE
without an argument will display either " " or " ".
NONE ACTIVE ACTIVE
means that security/encryption has been enabled, but the radio will not
display the security argument.
When a value is active, all radios in the system must use the same code
CODE
value. If the code value is not properly programmed, a remote radio will not
synchronize with the master.
CAUTION: Record the value and store it in a safe place. If the code is
CODE
later forgotten, and a unit is to be added to the system, all radios in the
network must be set to and then reprogrammed to a new value.
NONE
CTS [0–255]
The (clear-to-send) command sets or displays the timer value associated
CTS
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.
For CTS Key operation (see the command), the timer specifies how
DEVICE
long to wait after asserting the CTS line before sending data out the
DATA
port. A timer value of zero means that data will be sent out the data port
without imposing a key-up delay. (Other delays may be in effect from other
radio operating parameters.)
