GX GSM
DRAFT: function & product not released yet.
1. Introduction
The GX GSM is an accessory for Venus-devices. It is a cellular modem; providing a mobile internet connection for the system.
It requires a SIM card; and connects to the Venus-device with a (supplied) ??m USB cable.
A small indoor GSM antenna is included. As an option we also sell an outdoor GSM antenna. (Add partnumber; and somewhere there must be a picture of it and specs, GX GSM datasheet!?)
GPS
Besides internet, the GX GSM also has a GPS receiver. To use that, buy the optional active GSM antenna. (Add part number)
Compatibility
- Color Control GX
- Venus GX
- Octo GX
The GX GSM requires Venus OS v2.20 or newer to be installed on the Venus-device.
When to use a mobile router instead
The GX GSM only provides an internet connection for the Venus-device: there is no option to share the internet to laptops, phones, or other devices.
For installations where more devices need internet, such as a yacht or RV, consider installing a mobile router instead. More information here (link to proper chapter in Ccgx manual).
2. Installation
Mount the device an connect the antenna. Consider using the outdoor antenna when installing the GX GSM in a closed metal enclosure.
Insert the SIM card.
Connect the GX GSM to the Venus device with the supplied USB cable. Use a USB hub in case all USB sockets are already in use.
Connect DC power supply (8 to 70 VDC).
3. Configuration
When using a SIM card with its SIM-pin security disabled, the system will work without further configuration. Verify operation by .. ? (Check VRM Last log data?)
Setting a SIM pin helps reducing the risk of the SIM card being stolen and used. Use a mobile phone to set the SIM pin, and there after configure it on the Venus device.
Settings → GSM modem → PIN code
Some mobile networks require manual configuration of an APN specially when roaming. Contact your operator.
APN name can be configured in Settings → GSM Modem → APN.
