4800 Baud Rate - Unlike other games, which use a 9600 baud rate, Time Traveler requires the Sony laserdisc player to be set at 4800 baud, with the DIP switches (or rotary switch) on the back of the player set as follows:
Sony LDP-1450 - 1-down 2-down 3-up 4-down *
Sony LDP-1550 - 1-down 2-down 3-up 4-down
Sony LDP-2000 - 1-up 2-down 3-up 4-down
Sony LDP-3600D - Turn the rotary switch to the 4800 baud position.
* The Sony LDP-1450 has an additional bank of six switches that must all be set in the down position.
