g307K2
The G307K2 has three serial ports, as well as an Ethernet port. The serial
ports are exposed via one DB9 male connector, and one DB9 female connector.
You may assign one unique protocol to each of the ports for a total of three
different serial protocols.
Note: If you assign a protocol to the Programming Port, you will no longer
be able to download. You should create a means to call the StopSystem()
function from the HMI touchscreen, such that the Programming Port activity
can be halted on command. Alternatively, the HMI's memory can be cleared to
restore download functionality.
The Ethernet port can be programmed to communicate via four protocols
simultaneously. For more information on protocol support, please refer to the
Crimson 3 programming software.

CONNECTING POWER
The G307K2 requires a 24 VDC ±20% power supply. Please take care to
observe the following points:
- The wire used to connect the operator interface’s power supply should
be at least 22-gage wire. If a longer cable run is used, a heavier gage
wire should be used. The routing of the cable should be kept away from
large contactors, inverters, and other devices which may generate
significant electrical noise.
- A power supply with a Class 2 or SELV rating is to be used. A Class 2 or
SELV power supply provides isolation to accessible circuits from
hazardous voltage levels generated by a mains power supply due to
single faults. SELV is an acronym for “safety extra-low voltage.”
Safety extra-low voltage circuits shall exhibit voltages safe to touch
both under normal operating conditions and after a single fault, such as
a breakdown of a layer of basic insulation or after the failure of a single
component has occurred.
