Communication

 

Problems

 

Networks

 

separated

 

by

 

physical

 

routers

 

will

 

often

 

block

 

UDP

 

broadcasts

 

preventing

 

WinDiscovery

 

from

 

locating

 

devices

 

on

 

a

 

remote

 

network.

  

Under

 

such

 

circumstances,

 

WinDiscovery

 

must

 

be

 

operated

 

from

 

a

 

computer

 

within

 

the

 

remote

 

network.

 

Or

 

the

 

routers

 

separating

 

the

 

networks

 

must

 

be

 

configured

 

to

 

pass

 

bidirectional

 

UDP

 

traffic

 

(including

 

broadcasts)

 

on

 

port

 

6163

.

  

Consult

 

your

 

network

 

administrator

 

for

 

additional

 

information.

 

Personal

 

or

 

network

 

computer

 

firewall

 

applications,

 

or

 

the

 

Windows

 

OS

 

firewall

 

may

 

also

 

prevent

 

WinDiscovery

 

from

 

operating

 

correctly.

 

Configure

 

the

 

firewall

 

to

 

allow

 

bidirectional

 

UDP

 

traffic

 

on

 

port

 

6163

 

or

 

temporarily

 

disable

 

the

 

firewall

 

while

 

using

 

WinDiscovery.

 

 

Troubleshooting

 

Tips

 

 

All

 

GMR

 

units

 

are

 

fully

 

checked

 

and

 

system

 

tested

 

at

 

the

 

factory

 

for

 

proper

 

operation

 

before

 

shipment.

 

Unless

 

physical

 

damage

 

is

 

found,

 

the

 

unit

 

is

 

probably

 

functional.

 

The

 

following

 

problems

 

can

 

probably

 

be

 

readily

 

solved

 

by

 

the

 

customer/user.

 

Software

 

Tip:

 

WinDiscovery

 

uses

 

bi

‐

directional

 

UDP

 

messaging

 

on

 

port

 

6163

 

for

 

both

 

the

 

discovery

 

process

 

and

 

to

 

communicate

 

configuration.

 

It

 

also

 

sends

 

status

 

packets

 

to

 

and

 

from

 

all

 

Masterclock

 

network

 

devices

 

on

 

this

 

port.

  

Delivery

 

of

 

UDP

 

messages

 

(packets)

 

is

 

NOT

 

guaranteed.

  

Intermittent

 

problems

 

with

 

WinDiscovery?

 

Try

 

closing

 

the

 

current

 

session

 

and

 

restarting

 

the

 

application.

 

If

 

this

 

does

 

not

 

resolve

 

the

 

issue,

 

try

 

some

 

of

 

the

 

trouble

 

shooting

 

tips

 

listed

 

here.

 

If

 

this

 

fails,

 

switch

 

to

 

an

 

alternate

 

method

 

of

 

configuration,

 

such

 

as

 

SSH

 

or

 

Telnet.

 

A

 

”soft”

 

restart

 

may

 

be

 

performed

 

once

 

per

 

hour

 

by

 

the

 

GMR

 

to

 

automatically

 

if

 

the

 

GMR

 

is

 

set

 

to

 

use

 

DHCP

 

and

 

cannot

 

find

 

it.

 

You

 

will

 

recognize

 

a

 

soft

 

restart

 

when

 

the

 

GMR

 

green

 

PWR

 

LED

 

begins

 

to

 

blink

 

twice

 

per

 

second

 

for

 

a

 

short

 

time.

 

You

 

may

 

even

 

hear

 

a

 

quiet

 

relay

 

click.

 

 

PROBLEM:

  

 

Unable

 

to

 

find

 

(discover)

 

the

 

new

 

GMR

 

in

 

WinDiscovery.

 

POSSIBLE

 

REASONS/SOLUTIONS:

 

1.

 

Verify

 

that

 

you

 

have

 

supplied

 

power

 

to

 

the

 

GMR.

 

2.

 

Verify

 

that

 

all

 

the

 

network

 

cables,

 

hubs,

 

etc.

 

are

 

in

 

proper

 

working

 

order.

  

3.

 

Be

 

sure

 

that

 

no

 

Ethernet

 

crossover

 

cables

 

are

 

being

 

used

 

where

 

inappropriate.

 

4.

 

After

 

clicking

 

the

 

Discover

 

button,

 

wait

 

until

 

the

 

status

 

indicates

 

100%

 

completion.

 

5.

 

Verify

 

that

 

the

 

GMR

 

is

 

a

 

Masterclock

 

brand

 

device.

 

WinDiscovery

 

is

 

not

 

designed

 

to

 

work

 

with

 

products

 

from

 

other

 

vendors.

 

6.

 

Verify

 

that

 

the

 

GMR

 

is

 

on

 

the

 

same

 

physical

 

network

 

as

 

the

 

computer

 

from

 

which

 

you

 

are

 

running

 

WinDiscovery.

 

7.

 

If

 

the

 

computer

 

is

 

separated

 

from

 

the

 

GMR

 

by

 

a

 

router

 

(on

 

a

 

remote

 

network)

 

or

 

a

 

firewall

 

it

 

is

 

likely

 

that

 

the

 

router/firewall

 

is

 

blocking

 

communication

 

with

 

the

 

device.

 

Run

 

WinDiscovery

 

from

 

a

 

computer

 

within

 

the

 

remote

 

network,

 

or

 

ask

 

a

 

network

 

system

 

administrator

 

to

 

configure

 

the

 

router/firewall

 

in

 

question

 

to

 

pass

 

through

 

(in

 

both

 

directions)

 

UDP

 

broadcasts

 

on

 

port

 

6163.

 

If

 

this

 

does

 

not

 

resolve

 

the

 

detection

 

problems

 

you

 

may

 

additionally

 

configure

 

to

 

pass

 

through

 

both

 

directions

 

UDP

 

broadcasts

 

on

 

ports

 

6165

,

 

6166
