1. Key Rollover. This parameter controls how many keys may be pressed at the
same time and be accepted by the keypad. Because the Bump Bar version
uses double wide key caps, 2-key rollover is recommended.
o
1 Key: When one key is held down, the keypad will recognize no other
key(s).
o
2 Key: Two keys pressed and held at the same time will be recognized by
the keypad. Additional keys will be ignored. Two key rollover is required
when using a shift level access key or double size keys.
2. Inter-character Pacing. This parameter inserts a short pause between all
bytes sent to the PC. The range for this parameter is 2ms to 20ms. It has the
effect of slowing down the typing slightly in case you are working with a slow
PC.
3. LED Function. You may select one of 4 modes for the LED on your keypad.
The default is for the LED to perform no function (Off/Not Used). You may
assign the LED to illuminate when the keypad’s 2
nd
level is active (Level
Indicator). You may control the LED from the Host PC. You may set the LED
to be a power indicator/keypress indicator. In this final mode, the LED is
always on except when a key is down.
4. Download Delay. You may include short pauses in the download process to
give the host PC and keypad time to synchronize during the download
