| 1) Serial attachment | 2) IP-based via serial splitter | Data from transaction system 3) ASCII via TCP/IP 4) XML via TCP/IP |
| How? | Serial cable from device to PC/Server. | Using a serial splitter, the data is converted to IP using a serial IP converter. Data is then captured via IP directly onto the server. | A software plug-in (custom provider) is made to capture the data from the transaction system. |
| Suitable for | Very small installations | Small to medium installations | Large installations |
| Advantage | Inexpensive. Only cabling required. | Uses existing IP networks. Unlimited number of devices per server. Not limited by distance. | No cabling of extra hardware needed. No limitations in number of devices. |
| Disadvantage | Extra cabling required. Limited in distance. Limited by available COM ports on server. | Extra hardware needed (serial splitter and IP converter) | Programming required (typically done by Milestone consultants) |
