Gemini GV6K and Gemini GT6K Programmer's Guide

Programmable I/O Bit Patterns
The Gem6K has programmable inputs and outputs. The total number of onboard inputs and outputs (analog inputs, digital
inputs, and digital outputs) is fixed. The total number of expansion inputs and outputs (analog inputs, analog outputs,
digital inputs and digital outputs) depends on your configuration of expansion I/O bricks.
These programmable I/O are represented by binary bit patterns, and it is the bit pattern that you reference when
programming and checking the status of specific inputs and outputs. The bit pattern is referenced 1 to n, from left to right.
• Onboard I/O. For example, the status command to check all onboard digital inputs is TIN.
An example response is: *TIN0100_0.
• Expansion I/O. For example, the status command to check all digital inputs on I/O brick 2 is 2TIN.
An example response is: *2TIN0010_0110_1100_0000_XXXX_XXXX_XXXX_XXXX.
