• Station does not receive or acknowledge the codes sent by the panel – wrongly

selected format, inadequate identifier length (3 characters, while the station requires 4),

inadequate event code length (1 character, while the station requires 2) or low quality of

telephone connection.

Note: For the Ademco Express transmission format, the identifier „0000” is valid (sending

zeroes is possible), however it is not valid with the other formats (sending zeroes is

impossible).

A headset connected to the "telephone line monitoring" jack in the SM-2 synthesizer can be

helpful in analyzing the problems with communication to the monitoring station.

Connection with the station is established in the following way:

• the station answers the call and sends the, so-called, handshake signal (one or a few in

sequence if the station supports several transmission formats),

• the control panel recognizes the station handshake signal and if it matches the

programmed transmission format, the control panel answers by sending identifier and

event code in appropriate tones (once or twice, depending on the selected format) – in the

headset connected to the line monitoring jack, these sounds are much louder than the

monitoring station signals,

• if the station receives information, it will acknowledge it with the same signal as the

handshake,

• the panel disconnects or sends next codes if there still are some other events to be

reported to the station.

The most common monitoring problems result from inaccurate information on the

transmission formats supported by the given station (e.g., ambiguous names of the formats),

errors in the data entered into the control panel, as well as poor quality of the telephone

connections. Often only by “monitoring” process of communication you are able to find the

cause of a problem.

Note: Some stations do not acknowledge reception of the event code if it has another format

(e.g., 4/1 instead of the required 4/2). If this is the case, the control panel will repeat its

attempts to establish communication, while telephones in the facility will be

disconnected – the costs of such connections may be very high. For this reason, it is

recommended that all the programmed codes be very carefully checked. It is possible

to activate the options 7 and 8 in FS47, which makes the panel ignore the codes

unacknowledged in 16 consecutive retries. Problems of this type do not occur in

professional, multi-format monitoring stations (including the Satel STAM-1).

Downloading – communication with computer

Programming the control panel through RS TTL serial port

The programming is possible with the use of a special cable (see: p. 12). To run the

software, select a suitable COM port number in the DLOAD10 program (“Configuration”

window). Then, from the “Communication” menu, select the

→

“Local connection

with...”, and, subsequently, select the control panel type (e.g.

“

CA6v5 - RS-232(TTL)”).

Activate the service function FS112 in the control panel. Consistency is required between

the panel and the computer communication codes (FS2 and FS3) programmed in the

panel and included in the DLOAD10 program data.

Programming with the use of modem

Telephone communication with the computer requires a modem. The modem must meet

two essential conditions:
