! 8 Bit Word Specifications

DATA 1 and DATA 0 signals are open collector outputs with 2.2K

pull-ups to the internal +5V. The data is sent at 1 msec per bit with

a pulse duration of 50 usec. An annunciator beeps with each key

press. An output is generated with each key press which can be

used to drive a CCTV or Security Light. Located through the BLUE

wire (see Connector Wiring), this is an open collector output

capable of sinking 1/4 A with a 30 second on time.

Each key press generates an 8-Bit sequence in the following

output format:
