Series 90 Setup Manual
Series 90L4/Series 90H8 Scanner Control
The Scanner Control Boards in the Series 90L4 and Series 90H8 are designed to communicate
through a serial port (COM) instead of a Cablescan I/O board. Since a PC serial port cannot be
daisy chained, the Series 90L4 and Series 90H8 are limited to one cabinet (512 test points). For
Series 90L4 and Series 90H8, the other external signals, which include the footswitch and wrist
strap connections, and the remote signals, are available on one of the PC’s parallel (LPT) ports,
controlled by Series 90 software. Refer to the section on Remote Signals for pin assignments.
