10.1 Introduction
The GLK19264-7T-1Usupports up to a 7 Key, matrix style, embedded keypad and may be configured
to allow key presses to be automatically transmitted via RS-232 or polled through I 2 C. The GLK19264-7T-
1U also allows for auto-repeating key presses. The keypad is scanned whenever a key is pressed;there is
no continuous key scan. This means that key presses are dealt with immediately without any appreciable
latency. This also prevents electrical noise which is often caused by continuous key scans.
The keypad is tactile with seven keys. The value of each key is listed in the table below.
