Die serielle Platine stellt über eine serielle Schnittstelle die Verbindung zur Aussenwelt her. Diese Schnittstelle wird über die Busplatine an deren Anschluß J1 zur Verfügung gestellt. Dort kann man dann ein seriell zu USB Wandlerkabel anschließen und mit einem Computer als Terminal Ersatz verbinden. Hierbei ist auf die Pinbelegung zu achten, da diese nicht wirklich genormt ist.
