CHAPTER 3
PROGRAMMING ESTEEM FEATURES
Revised: 27 March 01
3-3
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 more than one
ESTeem 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.
AUTO CONNECT
The Auto Connect feature allows the user to program the
ESTeem to perform a CONNECT to another ESTeem
when data is sent to the RS-232C communications port.
To enable this feature perform the following from the
COMMAND MODE:
SETCON (1-255) = Address of destination ESTeem.
Remember, you can use the Repeater routing
(r1,r2,r3,da) or put the ESTeem in Global (address 255).
SETCON is the set connect command.
SA SAVE command. This will save the SETC
variable to the non volatile memory so that it
will not be lost when the ESTeem is RESET.
Bit 2 (on/off) = On. Bit 2 is located on the RS-232C
SETUP SWITCH on the front of the
ESTeem. The ESTeem must be
RESET after the Bit has been changed
to be read by the ESTeem CPU.
RESET ESTeem RESET is located on the front panel
OFF/ON switch. The T/E light on the
front panel of the ESTeem should now
flash at a two times per second rate.
MULTI-CONNECT
The actual polling of the ESTeem must originate from
the host device connected to the ESTeem using the
CONNECT command to originate the initial connect and
the COMMAND character to return from the
CONVERSE mode to the COMMAND mode. The first
time around the pole a CONNECT data packet (rf
transmission) will be initiated. When a link is
established, it is held internally in the ESTeem connect
table. The next time around the pole to the same address,
the link status will be checked in the ESTeem table. If
the address indicates a link has already been established,
then only data and its corresponding ACK will be
transmitted to that node. This greatly increases polling
time by eliminating the usual
CONNECT/DISCONNECT sequence each time except
when communication is first established.
The MULTID command allows the user to send data to a
specific ESTeem address from the CONVERSE Mode by
specifying the ESTeem address routing before the data
packet. This feature will also display the address of the
sending ESTeem on any received data.
