GLOBAL BROADCAST
Global broadcast is the ability of one ESTeem to transmit it's message to more than one ESTeem at one time. All ESTeems within
radio range will receive the message whether or not they are connected to another ESTeem or in command or converse mode.
You can put your ESTeem in Global by connecting or programming the SETC to address 255. Address 255 is a non-assignable
unit address and is used by the ESTeem CPU to access this special mode. When the ESTeem is in Global, the standard ACK
protocol from the receiving ESTeem is disabled, but the 32 bit CRC error checking on the received ESTeem is still operational.
When you perform CONN 255 <Enter> from the COMMAND MODE the ESTeem will immediately go to the CONVERSE MODE
(* is displayed). All messages sent will be transmitted globally to all ESTeems in radio range.
In the ESTeem you have a GLOBAL (on/off) command. When GLOBAL = On, you can receive Global transmissions. If
GLOBAL = Off you will not display Global transmissions from other ESTeems.
Note: Factory default is ON.
By using the repeater function you can transmit Global messages from another ESTeem using the Digi-repeating feature.
Example:
CONN 10,20,30,255<Enter>
SETC 10,20,30,255<Enter>
By adjusting these commands you can route from unit 10 to 20, 20 to 30, and go Global at unit 30.
You can enable global transmissions in one or more ESTeem’s in your network. This will allow global communications between
all ESTeems within radio range.
AUTO TRANSMIT
The Auto Transmit feature of the ESTeem allows the user to transmit a data packet without filling up the PACKLEN (packet
length) buffer or defining a special control character using the SENDPAC (send packet) variable. The Auto Transmit feature is a
timer that is enabled in the ESTeem that monitors traffic in and out of the RS-232C port. If there are characters in the RS-232C
buffer, the termination control timer starts from the time the last receive or transmitted character is updated in the buffer. If the
termination time expires before another character is received or transmitted, the received characters are transmitted.
To enable this feature perform the following from the COMMAND MODE:
TERMC (on/off) = On. Enable termination control.
TERMT (10-65535) = One unit number equals 1ms.
TERMC is the termination control command. TERMT is the termination time command. Factory default for TERMC = Off and
TERMT = 50.
