DACOM Interface
DACOM is a current loop connection with a source voltage of 24 V. Normally,
DACOM transfers data at 2400 baud, 8 bits, no parity and 1 stop bit.
The Interface Board provides the 10-way header P21 for connection to a DACOM
5000 system parallel to the Channel 3 connector. The DACOM signals are shown
below.

Bally Serial Interface
The Bally serial interface is a current loop interface defined by the Bally Gaming
organisation. The facility normally runs at 9600-baud rate, 1 start bit, 8 data bits, 1
stop bit, and no parity.
Data line input to Bally is an npn transistor collector with 1K pull-up resistor to
5 V. Idle state is transistor on for an output low. The Bally signals are shown below.
Only a Tx line, an Rx line, and a Blackout line are required for the Bally Interface.
