# Single (B2 and Coolguard)

To set the CG1018 to operate with B2 or Coolguard (RQS) server in SINGLE mode define:

**URL\_MAC=0** and **URL\_DUAL=0**

The settings shown below set **SINGLE** mode and define server at IP address equal to **81.91.10.237**. 

The alarms signaled by the unit are selected basing on the ID at the end of SERVICE\_URL line which is ICU\_MANKAN\_INTERNAL\_TEST\_CGNS\_GW in the example. 

{% code overflow="wrap" %}

```sh
# B2 or RQS (only reads temperature-alarms of two URL's)
#URL_DUAL=0 -> Uses the SERVICE_URL to get status from server (older behaviour of Blixtljus where a single URL controls both relays)
#URL_DUAL=1 -> Uses the two URL's SERVICE_URL_CH1 and SERVICE_URL_CH2 to control the two relay outputs individually, only temperature-alarms (ie. 1x) from URL will control the outputs (server's communication alarm status is ignored).
URL_DUAL=0
SERVICE_URL_CH1="http://81.91.10.237/strobelight.aspx?User=HUS_CH1"
SERVICE_URL_CH2="http://81.91.10.237/strobelight.aspx?User=HUS_CH2"


# B2 or RQS (old standard URL)
#Use either URL_MAC or URL_DUAL solution (above), OR, SERVICE_URL (don't try to use both)
#SERVICE_URL="http://81.91.10.237/strobelight.aspx?User=HUS_CH1"
#SERVICE_URL="http://192.168.61.156/rasp.html"
SERVICE_URL="http://www.rqs.se/bl/?id=ICU_MANKAN_INTERNAL_TEST_CGNS_GW"
```

{% endcode %}

Sensor alarms control CH1, and communication alarms control CH2.

The URL for Coolguard (RQS) in the example looks like this:

```sh
SERVICE_URL="http://www.rqs.se/bl/?id=ICU_MANKAN_INTERNAL_TEST_CGNS_GW"
```
