In normal operation this is used to show the current interface status of the SPT.  Which interface is currently being displayed depends on the position of the DIP switch 4.  In the switch 4 off state, the unit shows the status of the GSM interface.  When switch 4 is on it shows the status of the ‘other’ interface (IP or PSTN).

For GSM Display (dip switch 4 – off)

Display off

Normal state when the tamper connection is closed

0-9 or A

Signal strength where 0=no signal, A=highest possible strength

0-9 or A + flashing ‘.’

Shows signal strength while GPRS is on line. The GPRS connection should only remain on while messages are being sent (either alarms, polls or upload/download), and should be cleared 30 seconds after a message has been sent providing no more messages are in the queue to be sent.

0-9 or A + ‘no gsm’

Shows signal strength but there is no GSM registration

0-9 or A + ‘no GPRS’

Shows signal strength, GSM is registered but there is no GPRS coverage

‘no module’

Module is missing and has never been seen

‘no SIM’

Module cannot detect a SIM

‘no signal’

There is no signal detected

‘phone fault’

There is an undiagnosed problem with the GSM module hardware itself

‘SIM  error’

There is a problem with the SIM used

‘no PIN’

SIM requires a PIN and there is no PIN specified in configuration

‘PIN error’

The wrong PIN has been sent to unlock the SIM

‘PUK error’

The wrong PIN has been sent to unlock the SIM too many times and the SIM is now locked; requiring a PUK (unlock) code

‘not ready’

Module is being initialised

‘unknown error’

Shown only if the module produces an error not specified in its manual. In practice the manual covers all the standard CME error messages and so this should not be seen.  But you never know.

For IP Display (IP units with switch 4 – on)

‘no eth.’

When the Ethernet connection to the local hub/switch is missing


Ethernet lower IP layers are still in negotiation

‘no router’

The default gateway ping feature has been enabled (value of ROUTER_PING is non-zero) and the ping is failing


10-base T connection – half duplex

‘t’ with ‘.’

10-base T connection – full duplex


100-base T connection – half duplex

‘h’ with ‘.’

100-base T connection – full duplex

The Bi-Colour LED Displays

SMG – Gateway configuration & commission status:

Flashing Orange – Initialising – system not ready yet
Red / Green Alternate – No valid configuration
Flashing Green – Commissioned
Flashing Green with brief Orange flash after each Green – Commissioned with incomplete (but usable) configuration
Flashing Red – Not Commissioned

MSG – Message status

– Messages are queued and have not been sent
Green – Messages have been sent but not acknowledged
Off – No messages waiting to be sent or sent but not acknowledged

ATS – Path and Interface Status – one flash for each path followed by a gap.  Each flash means:

Green – Good path on good interface
Orange – Good path but interface unusable
Red – Bad interface (path may or may not be OK but is unusable while interface is dead)

EXT – External port – Shows the data flow for the optional serial alarm panel interface

Red for data from the external device to the WebWay 
Green for data from the WebWay  processor to the external device
PNL - Panel indicator – Shows the data flow for the serial alarm panel interface

Red for data from the alarm panel to the WebWay 
Green for data from the WebWay to the alarm panel
