This manual covers installation and reference infor-
mation (or Monitor equi meat, and will answer
most questions regarding t the of Monitor equip-
ment. The introduction contains descriptions and
important general information. This installation
section tells how to set up a basic system. The
remaining sections contain detailed reference infor-
mation for operation and application options. See
the “Systems a Accessories“ section for help in
selectingst components.
OVERVIEW
Monitor radio modems provide IRS-232 ASCII
portable data communication over a single narrow-
band UHF radio channel to eliminate data cables for
up to several miles. Monicor systems consist of
many diﬁ'erent radio modem nets for different
apphcalious. All of these use the same principles of
operation which are covered in this manual. Each
radio modem has a Headee communications port
that ran be conﬁrmed for any type of equipment.
Two types of radio operation are available:
1. LinkOperation
2. Multidrop Operation
Most installations use link" operation, which is the
default.
Link Operation
Link Operation transfers information over the radio
via variable length synchronous packets of data.
with full error deteuion and correction. Information
is buffered at each full duplex communication t.
Flow control (either C'I‘S/D’I‘R or XON/XOFngn
be selected.
The minimum system (one network controller unit
and one portable unit) acts like a wire linlt. Data
input at one end is strut out the other. This means
that a radio link can be installed into it system with
N0 ADDED SOFTWARE.
The network controller handles data transfer for one
or more able radios, A simple “ti-wit switch“
com-nan issued the host switches the current
circuit of the centre e: interface. Each circuit (data
path between a terminal and the host) is fully buff-
ered so that the radios can transfer data automatical-
ty while the host swim the controller port to one
mcuil at a time. It simply sends and receives data
to m the bullets of the current circuit.
madman ileum Mutual, tmazwm
A} many as 99 remote radios may operate with a
single network controller on a sing|e radio ﬂannel.
The host can check the status of a circuit to sense if
there is any activity by any portable tenninal. Only
one network controller may operate at any one time
on a single radio fresuency. Multiple network
controllers may he use at any given time. providing
that theyare all on separate frequena‘es or have an
adequate separation distance.
Each radio modem is conﬁgured independently.
Conﬁguration parameters include Baud late swings,
interface proﬁle (edit. standard or transparent), the
orlablc Link Number and the controller Link
5mm, the ﬂow control, etc.
Most installations use ‘ljnlt" operation. which is the
default. However. most installations require the
'tnnsparent' proﬁle, and this must be selected and
‘written' into each radio alongwith the link number

In the data transfer mode, data transmitted from a
terminal or hon to the radio and is forwarded
to the oorretpo in; remote terminal (or host)
In the command mode, terminal output is interoept~
ed and interzreted as commands by the attached
radio . and t e terminal receives radio generated
responses (TAD Service Signals") instead of
remote transmitted data The terminal controls the
relive mode by sending certain commands.
Data Transfer Mode
In the data trtnsfer mode, terminal output is collect-
ed in an edit buﬁer and mmblml into asked; when
a forwarding condition is met. The pa ctr are then
sent to the remote terminal. Inoornmg paeltets from
remote terminals are disasemtded into the original
characters and transferred to the terminal as re;
ceived data.
An edit bum: is a reserved space for each circuit
where trunrmit dataisheltl until a forwarding oondi~
tion occurs (see figure 1).
A wtd tire is a reserved space for each circuit
that can Id up to two packets for radio transmis.
sion. Aﬁer a forwarding condition occurs. the send
queue will grab data from the edit buffer as soon as
there is an empty packet slot (less than two packets).
mmMmMaMlmml
The amount grabbed will be as much as can be
forwarded (for which one or more forwarding condi-
tions apply). but no more than the nrnzr'mimr pocket
size, which depends on the Link Size parameter.
(The edit bullet is always larger thin the maximum
parlor aim.)
This creates a new packet, which contains one or
more char-ardent of user data. and increases the free
space in the edit buffer.
Packets received from another radio are pinned in
the rueive queue. This is an area of memory re~
served for each circuit and holds up to two packets
pending delivery to the local terminal.
“terminal may force the radio modern to switch
from the data transfer mode to the PAD command
mode (crane from data transfer). The options for
escape from the data transfer mode depend on
several PAD parameters. One 0 ‘on allows ‘l’ to
be used as an escape command armor. Another
option alltwvs use of the following sequence:
+++.
with the Al’ option, if two “I”: are transmitted to
the radio modem. the second brings the PAD inter-
face right back to the data transfer mode and is put
into the edit buffer.
Etenpe from data transfer is a forwarding condition
for the contents of the Edit Buffer of the current
eirtuit. The circuit switch oommund also constitutes
a forwarding condition.
when a radio modem escapes from the data transfer
mode tothe PAD command mode, the o ‘to end
of the eireuit does not receive explicit indication.
But sister; the command mode prevents mived darn
delivery, the other end might see data backup aﬁcr
enough putltets are sent. until delivery is rmmcd.

PAD Command Mode
In the PAD command made. all data from the
terminal is interpreted by the load modem as PAD
commands. and all data from the modem to the
terminal are local modem-generated responses
(service signals). No data is exchanged with the
circuit queues. although the queues can still ex-
change packets across the link Service signals are
generated in all rol'tles while in the PAD command
mode. Dcpen mg on the proﬁle, service signals
may also be generated in the data transfer mode in
response to modem or remotely generated events or
in response to terminal issued status subcommands
on circuit tern (see ﬁgure 2).
The '+' character (deﬁned by the I’L’Irr parameter)

All unused control characters are echoed as BEL

when a command or parameter is not acceptable,
only the first unacceptable character is echoedr
Each unacceptable character is echoed as the BEL

'ERR' is returned, sometimes followed by addition-
al information about the problem.

In the command mode, limited eomniandiline edit-

fer mode only if ”EDil' is enabled.
For sumt: ol'thc following details, note that the radio
distinguishes certain characters delivered to the
terminal as printing characters, and keeps track of

inlg there is one) according to the delitery se ncnec

except for 127 (DEL). The ES (8) decrelscs the
column by t. and the CR (13) resets the column
count to were (the lelt). The radio also counts LFs
delivered (tor pagtng purposes).

a character from the buffer when an errur has been
detected will also cause any other characters {allow

that the ee oed output will encounter the 255 charac-

Flow Control
Flow control is usedlyyeach device on the RS-m
link to regulate the data being sent from the device
at the other side of the IRS-m link. The terminal
may exercise ﬂow control 0! received data at any
time as desired. Flow control is exerted by the
modem according to the following two conditions.
in the PAD command mode, transmitted data itshut
all only when more than 191 characters are re-
ceived, but not yet procesed.
The radio continuously processes (removes) data
[mm the input buffer. but sometimes the processing
is slower than the maximum its-232 transmit rate,
especially at the higher baud rates.
Transmitted data is shut 0“ in the data transfer
mode when either the edit bullet for the circuit is
nearly lull (about 20 characters belore overﬂow,
depending on Facilities Protocol Pull), the circuit is

these data transfer eases, the terminal may (and
should) ignore the OFF condition tosendcornmands
(circuit switch and PAD escape). although a 255
character limit a lies in all cases ol unprocessed

Two primary methods of ﬂow control with the radio
modems are software and hardware ﬂow control.
With soltwttre ﬂow control, the churatters XON and
XOFF (“O and ”S) are inserted in the outgoing data
stream to indicate control ofthe incoming data
stream. The modern interprets these characters to
Matt or atop the now 0! received data to the terminal

Multl-Clrcnlt Flow Control
The terminals must manage ﬂow control in an elli-
eient manner to amid losing data. This applies [or
either hardware or software ﬂow control options.
For any two devices exchaag'ng data through a RS-
232 connection, flow control allows each device to
control its reception of darn by causin the other
device to stop or continue sendtn the ata. In the
System 200, flow control must e implemented
between the host and network controller and also
brawn the terminal and the remote radio modem.
Flow control prevents any loss at data under eondh
tints; which would otherwise require inﬁnitely large
buffers. Some of these conditions are:
A terminal has limited receiving capacity, sue]:
as a ' with a timed capacity. or a computer
having to wait for disk access. or a person
wanting to freeze a display until ﬁnished with
ll.
A terminal’s capability to transmit data extents
the radio link capacity, such as when transmie
ting much dataat a high bnud rate, when a radio
is temporarily out of range. or when many
cit-wits are active at the same time, diluting the
radio transfer of data (or the circuit of interest.
The radio-modem is temporarily busy and
cannot transfer data. such as white resetting a
circuit. or while a Ion uenoe oi commands
are being sent taster t an t ey can be executed.
A circuit is ‘down‘ and the network cannot
transfer data through it, such as when one of the
radius or terminals is off or disconnected.
A terminal stops received data. that data bein

or the echo soon prevents further processing ol

modern.
Certain commands are recognized in the data-trans-
fer mode. Sinoe these commands do not constitute
data. they may be sent even when flow control of
transmitted data (ND) is off. The terminal should
be programmed to ignore th'u llmrl control condition

When a terminal intends to send data toa circuit and
switches to that circuit, it should wall [or the edioed
circuit switch characters and determine the subse-
quent flow control indication helore ' to send
any data. Flam control will lie dctermin for that
circuit one: the switch characters are echoed. This
guarantees that the ﬂow control now applies to the

When software flow control is chosen, the signal to
turn off data in one direction is the transfer of the
XOFPdtnraetedDmmr’S) intheoppoaitediree

continue data. When hardware ﬂow control is

Data Transfer Timing
This section applies to LINK OPERATION, with
dynamic mode disabled.
The forwardinﬁ and reception offer-hatter] messages
over the radio ink is virtually transparent. As data
is input to a remote radio or networkcontlollcr from
the terminal, the tn are formatted internally
into individual punts. e packets are transmitted
under the control of the network controller, along
with routing intonation.
All units can hear from any other. Hem
er, only the destination unit stores and towards
each packet. Received pukets are then flanked for
errors. When an error is detected, the packet is
repeated as necessary.
Information packets may be of vaﬁablekmh, up to
a maximum of 128 bytes of data. ll a packet con-
tains only a low bytes. it will take a shorter time to
send the packet.
The network controller communicate: to each
remote radio circuit in the network sequentially. It
will normally be by the user to sequen-
tial access the maximum number of remote radios
on system (Link Quota).
The network controller continuously interrogates
each remote radio to determine its network autos;
i.e., whether it has been reset. is ready to transmit
data. or is ready to accept data. Packets are ex~
changed between each remote radio nndthe network
controller as the network controller messes eaeh
remote radio.
Packets originatingrom a remote radio will be
transmitted alter t t radio has been speciﬁcally
accessed. The packet will be transferred to the
aerialponal‘terthehmthnenmedtheeircuitto
the speciﬁc remote radio.
If the remote radio is taken out of range. and a
packet is then queued for sending in the remote
radio. the remote radio will accumulate messages in
its buffer until it is nearly full. At that point. the
remote radio will issue a ﬂow control signal at the
RS»232 port, inhibiting additional information until
it has more space in its buffer. When the remote
radio has re»estahlishcd oontart with the network
controller, packet llnwwill continue, and there will

The network controller can sequentially access

Programming Hints To
Speed Host Response Time
A general technique used for detenniningitreceiml
data is wni ‘ in the network controller [of circuit
access by the not from is to rule the status subcom-
rnand. by accessing circuit zero.
Aha switchin to circuit zero (using 0000, the ‘i‘
command. to lowed by a carriage return
will return the number ofcach circuit with received
messages. If a dash *.- is returned. no o'mtits have
emitted messages.
Once the host has switched to circuit mro, the status
subcommand i (mothers) mnysimplybe issued with
an i sequence [or as many tunes as neces-
sary. while still on circuit zero When it is desired
to change circuits the appropriate 0-digil-digit-0
command is issued and the network controller will
reply with the appropriate #-digit—digit—i response.
Sletus checks can be made as often as desired,
without slowing the speed of the message transfer
over the RF network.
Alter determining that there is received data on one
or more cimrits, the host can switch directly to each
circuit and avoid switching to idle circuits to in-
crease efﬁciency. especially for a large circuit
quote.
For some arrplleations, it maybe desirable to remain
with one circuit for a while, until data is transferred,
helm switching to another circuit. If it is desitotl
to m other circuits more or less equal priority. the
fol ‘ng method might be considered.
ll the status subcommand response to the Input
command indicates mes cs on multiple circuits,
such as 2,3,4, the host can t! issue the immediate
sequence without waiting [or a rcsporuo:
$02fmmmli< CR>
The response will be:
imﬁmcssagcfrommmﬂmﬂmessagefromm
here)#04#(memuge from 04 hereltllli < CRLF>i
2,3.4
SNote: the iwill not he echoed in the Transparent
rcﬁle)
This queues the switch commands to the network
controller replies with one packet from each of the
three circuits. The network controller will begin
delivering the data received from the ﬁrst circuit,
prundedhythecircuitswitchccho(' ). lfllae
network controller gets the comman to switch to
another circuit (as would happen with the above
sequence), it will switch circuits at the nest packet
boundary of data from that circuit.
The controller will indicate the switch to the host by
echoing the command sequence #-digit-digit-# to
allow the host to route data to the appropriate ﬁle or
task. The eitcuihswitch response rs not optional,
anti is not related to data-echo options.
For mph, ii the terminals each sent an 80 chatv
enter line of data. the command
imm#m#ﬂﬂii
would be used three times. After the ﬁrst and
second time, the status subcommand ‘i' would
indicate that there is still tlata in cimtits 2.3.4. Alter
the third time, il no additional data were recci'wd,
the ‘i' command would indicate "«'.
Note that it‘ outgoing data is to be inserted into the
above sequence, tlm host would need to wait follow-
inseuhclrcuit switchaﬁerwhich data istobescnt,
until the echo 0! the switch is received. At the point
tho switch echo is race-ind (the lost ‘l‘m the current
"or: status for transmitted data will pumped reﬂect
the destination circuit’s status and whet er the
outgoing data can be sent.
Thk is not necessary though. if the ‘o' or "95“ sub-
onmmuntl is used to determine which circuits are
flushed of outgoing data. The 'o' subcomntand
returns those circuit numbers with outgoing data still
present. The '%“ subcommantl returns complete
circuit status in one character for each circuit.
A ﬂushed circuit can accept two plus 2h
characters (send queue and edit ﬁcr. N = Link
Site) without loss. The host may send this much if
the outgoing circuit is ﬂushed without waiting at the
switch to ﬁnd out the flow control status.
If this method of circuit ﬂow control is used, you
will probably want to 'disaasociate' ﬂow control
from the current circuit so that several circuits of
outlput can he concatenated and ordinary flow con-
tro can be handled at the operating system level.

Communicate
The Communicate command places the modern in

Commands to enter the data transfer mode are:
‘C '
Data transfer begins for the currenl circuit (the
current circuit number is displayed).
"Cnn ‘
Data transfer beg'ns for the speciﬁed circuit (on),
which becomes the new current drcuit (no number
is displayed).
At power'on, the current circuit is 01. When C
is entered, data transfer begins for link
number one (01). The network controller can
communicate on any circuit by entering a C, the
circuit number (no), followed by a . For
example. communicate with circuit 04 bycntering;
CkClb.
A portable radio only has one circuit (01), which
goes to the network controller. If a remote is set to

In contrast to switching to any other circuit. a

when switching to circuit zero (0000 ).
i.e., the four character command 5700! has a six
character response instead of the normal four for
any other circuit.
By using a status suboonamand to see which circuits
have data waiting, thc host can switch directly to
any of these active circuits without having to step
through inactive ones.
Escape Communlettte
Several options are available in return to the
command mode. depending on the parameter set-
tings. See the Gard, I’Chr, and Pro parameters [or
the '+ r +' PAD escape option. See the Brit and
Pad parameters [or other escape options.
Primer-Up Mode
A radio will power-up irt either the command mode.
or the communicate mode. depending on the Mode
parameter. The odiitrilnlg to tlc sets the power-up
mode to command, transparent proﬁle sets
the power-up mode to communicate.
Default
This command sets all parameters to the factory
default values for the installed ﬁrmware version.
This is the same result as using a default conﬁgura-
tion plug at power-up.
This does not affect the power-u values. If the

Facilities Llnlt Dynumlc Drop
The controller drops a circuit [run the poll eyslc
alter the circuit is inactive for the speciﬁed control-
lcr drop interval. In addition. the portnble will
volunteer to the controller to be dropped after being
idle tor the speciﬁed portable drop interval. The
controller drop time should normnll be set much
longer then the porteblc drop time, owevcr some
systems may have a need to set some rtnble drop
times longer than others. The ports It: drop time
setting can dillcr between rubles if needed. The
controller factor default is eight seconds and the
portable futo eiault is one second. (See the log-
tirne section ow to ﬁnd the parameter value for u
desired time interval).
Fmilities Link Dynamic latency
The ﬁrst packet a portable uploads (after being
dropped) will encounter an extra delay, which is
alfectcd by the controller latency value. The ems
delay moi actually be more or less than the latency
value. T e delay is [or the unable to signal the
controller to add illothe poll cycle.
Page 24
The latency value inﬂuences the rate that signaling
by inactive radios is allowed. So a shorter latency
setting doweates the extra delayto start transfer. but
also causes more overhead (and less throughput) in
the network,
The latency value 3 ‘ res a time with 10 millisee

Facilities Llnk Dynamic Retry
Data packets are usually retransmitted it needed
until the other end of the link acknowledges error-
free reception. But dynamic polling will only re-
transmit duta packets a limited number of times
before sending a special request, which must be
acknowledged beiorc the data packet can be re-
transmitted This parameter limits the number oi
times the packet is first sent. it also affects the
controller drop-timer start. The retries are not
counted past seven.
Facilities Link Dynamic Skip
Skip allows the controller to skip polls every so
alien once the retry new is exceeded. A II will
then only occur on the 2 poll cycle, where is the
retry number minus the retry parameter. limited to a
maximum ofthe skip rumeter. (However, it is
also limited by the ra in not counting retrics past
sewn). For example, the factory do ault value of
two provides a minimum of one poll every four poll
cycles (until the circuit is dropped from the oil
cyde). So a portable might have to wait it to our
I cycles to get an upload started, even ough it
asn’t been dropped.
Facilities Unit Dynamic Test
The portable initiates a link test periodically while it
is dropped irom polling. Thls puts the link back
into the oil cycle if it was dropped while out of
range a data needs tobe transferred. The control-
ler does not initiate a test. The test result does not

MUL'I'I'DROP OPERATION

ordered ."’i’ the ‘a‘ ﬁrmware version option. A
radio using multtdrop operation broadcasts data
immediat y as a terminal begins to send it. All
terminals can receive all data. It is leﬁ up to the
terminals to coordinate transmission timrn and
error correction. Th‘u capability is typical ordi-
nary twisted pair mullldrop systems.
The concept of circuits, flow control, PAD inter-
