Quick start outputs
1.
Install SERA2 software. For more information look at
SERA2 Uploading/Downloading Software
2.
Connect the module to the computer via mini USB cable. Device> GTCOM2
3.
Go to Outputs (PGM) window in the SERA2 software
4.
Parameters of the selected output should be set:
output operation description (OUT definition): disable, bell, buzzer, flash, system state, ready, automation/ CTRL, AC OK, battery OK, ARM/ DISARM,
alarm indication, lost primary channel, lost secondary channel, fire sensor, RH sensor trouble.
5.
State type: flash, timer, steady mode.
6.
If necessary output operation might be inverted.
7.
Write configuration by pressing write icon
Outputs can be controlled in “Automation & Access control”, “Access Gained” modes.
8.
If you need to control outputs by short call or SMS, go to Sera2> Users/ Access control window and enter phone numbers of users, who will be
able to control selected outputs via free short call.
9.
Write configuration by pressing write icon
In order to control big power alternating current equipment, it is comfortable to use solid state relays.

Inputs
The module GTM1 has:
2 analog inputs (In1, .In2 (0-30V)) for analog sensors connection. Or can be used as security syst
em‘s zones with selectable type:
NC/NO/EOL/EOL+TAMPER.
2 programmable analog inputs (I/O1, I/O2(0-
30V) for analog sensors control or using as security system‘s zone with selectable type:
NC/NO/EOL/EOL+TAMPER
Wiegand interface, RFID reader, Keyboard.
1 programmable digital inputs (D1(Max voltage 3.3V)) used for:
o
Dallas 1-Wire Bus. To connect temperature sensors DS18b20 or iButton key DS1990A,
o
Aosong 1-Wire bus Humidity Sensor AM2302, DHT22, AM2305, AM2306,
3.5.1
Humidity sensors AM2302/DHT22/AM2305/AM2306/AM2320/AM2321
Module should work with following sensors: Aosong 1-Wire bus Humidity Sensor AM2302, DHT22, AM2305, AM2306. Also a new smaller sensor
exists AM2320 & AM2321.

The table lists values taken from datasheets. The Aosong data sheets do not specify maximum tolerances for most parameters, just 'typical' values. It
would therefore seem that any particular device is not guaranteed to meet these specifications. For all the other devices the numbers above are the
maximum tolerances and most also offer better 'typical' specifications.
