Field Definitions
MDC System Use the UP/DOWN arrow keys to change the MDC system or directly
enter the system number.
Primary ID Enter the four-digit hexadecimal for primary unit ID or use the UP/
DOWN arrow keys to select a primary identification code from 1 to
DEEE. The digit F is not allowed in the ID. The primary identification
code (PID) is in Binary Coded Decimal (BCD) format and indicates
which unit on the network sent the message. All out-bound messages
will be sent with this identification code.
Secondary ID Enter a hexadecimal value or use the UP/DOWN arrow keys to select a
secondary identification code from 0 (zero) to 0EEE EEEE for the
terminal. The digit F is not allowed in the ID. This is the secondary ID
assigned to the radio unit by the host. The secondary ID is related to
the position of the unit.
Variable ID Enter the ID directly. The Variable Unit ID is a three-digit hexadecimal
number ranging from 0 (zero) to EEE. The digit F is not allowed in the ID.
The Variable Unit ID is used to group radios so that several radios will
decode the same Selective Call or Call Alert.
Leading PTT-ID Use the UP/DOWN arrow keys to enable/disable the unit identification
data packet transmission at the beginning of each transmission (BOT).
If this feature is enabled, the radio will automatically send the radio’s
unit identification code to the dispatcher each time the microphone
PTT is pressed. If PTT-ID Sidetone is enabled, the user must wait until
the tone stops before he or she begins talking.
PTT-ID Sidetone This field will be visible only if the Leading PTT-ID field on this screen is set
to Enabled. Use the UP/DOWN arrow keys to enable/disable PTT-ID
Sidetones. During transmission of data packets, the microphone and
all voice transmission is automatically disabled. PTT-ID Sidetones are
used to indicate the end of transmission so that the user may begin to
talk.
If PTT-ID Sidetones are enabled, a continuous alert tone will sound as
soon as the PTT is pressed and will continue until the data packet(s)
has been sent. The user must wait until the tone stops before he or she
begins talking.
Trailing PTT-ID Use the UP/DOWN arrow keys to enable/disable the MDC unit
identification data packet transmission at the end of each transmission
(EOT). If the trailing PTT-ID feature is enabled and the microphone
PTT is released, the radio will automatically send the radio’s unit
identification code to the dispatcher.The PTT-ID Sidetone will NOT
sound for trailing PTT-IDs.
Radio Check Use the UP/DOWN arrow keys to enable/disable this feature. Enabling
this option allows the dispatcher to check the state of the radio (that
is, turned on or off), as long as the radio is within range of the system
(Clear mode).
