SnapCap is an accessory which converts RS-232 port on a 9-pin sub-D connector into an isolated half or full duplex (user-selectable via switch) RS-485 port on a 5-pin, 3,5mm pich, COMBICON connector.

You can follow this diagram to connect the RS-485 cable to the SnapCap:

          Where:

• B = Data-

• A = Data+

• G = GND

Firstly, connect the RS-485 in the SnapCap as shown in General Setup and connect the SnapCap to the RS-232 input in the M110 device. Finally, you are able to communicate via RS-485 with the device.

Firstly, download the file snapcap.sh and copy it in /etc/init.d/ (view Copy files with SCP)

snapcap.sh

snapcap.sh
Version: 1 – File size: 1 KB

Then, enter via SSH to the router (view SSH access)  and execute the following code:

chmod u+x /etc/init.d/snapcap.sh /etc/init.d/snapcap.sh enable

Reboot the device, connect the RS-485 in the SnapCap as shown in General Setup and connect the SnapCap to the RS-232 input in the E210 device. Then, go to Services>Serial and configure the Data Send Configuration as shown in the image bellow.
