6.0 Configuration
Values
S141
Repeaters Y/N
0 no repeater
1 1 or more repeaters
This register informs - and applies only to - the
Master as to the presence of any Repeater(s) in the
network.
With one or more Repeaters
in the system, a network’s
throughput is divided in half.
Exercising the option of back-
to-back ‘Repeaters’ - which
requires 2 modems at a
‘Repeater’ site - eliminates
the division of bandwidth.
If there is more than one
Repeater in a network, the
Repeaters
should
be
‘registered’. See Section 6.1
AT&H1 Repeater Registration
for how to accomplish this.
Values
S142
Serial Channel Mode
This register defines the physical serial interface which
will be used for data communications.
Note: When placed into
Command Mode, the module
will communicate via the RS-
232 interface at 9600bps,
8N1.
0 RS-232 interface
1 half-duplex RS-485
2 full-duplex RS-485
3 Full duplex, Tx always
on
Values
S140
Destination Address
1-65535
As the name implies, this register specifies the ultimate destination for a modem’s
data.
Different network topologies dictate the configuration of S140:
PMP
: Master S140=65535, Remote S140=1
PTP
: Master S140=UA of Remote, Remote S140=1
P2P
: Master S140=65535, S140 of each (of 2 / pair) Remote
modem is the UA of the other
E2E
: S140 of all modems=65535 (broadcast)
