Introduction
Interface Board - The interface board converts TTL level SSI signals to proper RS-232
levels for connection to any RS-232 compliant host. It also contains a red/green LED for
visual feedback, and provides for an external trigger and external beeper.
DB9 - The DB9 connector provides various interface signals used between a MiniScan
scanner and the host. It also maintains pin compatibility with the previous generation LS
1220 host cables.
Scanning Pattern
The MS-804FZY and MS-904HS scanners emit a single scan line to quickly decode 1D bar
codes.
