Giddings & Lewis 810-21721-00 SCSI D Interface Assembly

Technical SpecificationsModel：810-21721-00 Brand：Giddings & Lewis Product Type: PiC900 rack mount SCSI D peripheral interface assembly for CNC storage communication

Module Feature:Function: SCSI D bus interface adapter for PiC900 CNC system, establishes data link between PiC900 main CPU and SCSI storage peripherals, used for part program storage, CNC parameter saving and data exchange on heavy horizontal boring mills and machining centers. Bus standard: SCSI D interface Data transmission: High-speed parallel SCSI data transfer between controller and SCSI hard disk / storage module Onboard bus transceiver and signal conditioning circuit LED indicators: OK, ACT, FAULT diagnostic lights Hardware self-diagnosis:SCSI bus integrity detection, peripheral device recognition check, communication timeout alarm Programming software:PiCPro for storage device identification and data backup/restore operation

Electrical ParametersBackplane supply:+5V from PiC900 rack Peripheral power: SCSI connector power supply Power consumption:Max 3.3W

Mechanical & Structure:Mounting:Plug into PiC900 rack single slot Weight:0.22kg Protection class:IP20

Environmental:Operating temperature:0℃ ~ +60℃ Ambient humidity:5~85% non-condensing Certification:CE Status:Manufacturer discontinued legacy PiC900 SCSI interface module

System compatibility810-21721-00 belongs to Giddings & Lewis PiC900 control platform. Compatible with PiC900 backplane, CPU processor boards and SCSI storage drives. Widely fitted on G&L 70A horizontal boring mills and PMC CNC boring machines.

Function810-21721-00 is PiC900 SCSI D interface assembly manufactured by Giddings & Lewis. It acts as the communication bridge between PiC900 main processor and external SCSI storage hardware. It supports reading and writing CNC part programs, machine parameters and offset data to SCSI storage disk. It converts rack backplane signals to SCSI bus protocol, enabling reliable data storage and backup for heavy machine CNC control.

InstallationFollow lockout/tagout safety procedure before installation. Cut off rack backplane power. Insert 810-21721-00 module into PiC900 backplane slot and lock retainer. Connect SCSI cable to storage peripheral, set SCSI ID and termination correctly. Configure storage device parameters in PiCPro software. Power rack on, verify device recognition and file read/write function.
