Internet Explorer working fine but Google Chrome is not?

When you use a network addressing, you should always use the same routing.
Example: 192.168.1.100 Computer
192.168.1.200 Till
The only routing prefix that should change are the last 3 digits marked as XXX, Example 192.168.1.XXX
Try to keep them in the same routing prefix, never on different prefix.
Using the last 3 prefix makes the device PART of that NETWORK, when you change it, You're telling it to look for .2 prefix, Which BECOMES another NETWORK.
When you use a different prefix like you're doing, the system is trying to look up something on a different network, which it won't allow, not unless you change your ip address on the router, or modem.
Always keep the prefix the same such as above, when you changed the 1 for a 2 on the Till, you are creating conflicts on the network.
Change the settings of your Till software to 192.168.1.200, and then change it on the device itself if the software doesn't do it to the hardware, if the hardware needs it changed for the software to reach it you may need to look at the settings from the user's manual.
