1. Product Introduction

2. Electrical Specifications

• Communication: Dual auto-adaptive SUNMD + SUNID dual serial protocol (RS232 customized SUN bus), automatically identify WEStation mainboard interface signal, fully backward compatible with H01 SUNMD port and H02 SUNID port, no manual hardware jumper setup needed.

• Power Input: Rated DC5V directly powered from console internal power supply, typical power consumption ＜0.9W, lower power loss than H01/H02 versions.

• Internal Circuit: Built-in integrated PCB with enhanced ESD & surge suppression components, anti-EMI interference against cabinet relay, power module and field signal noise; pre-assembled left + right physical push buttons integrated into trackball assembly.

3. Mechanical & Environmental Parameters

• Housing: Standard black high-strength industrial ABS plastic casing, identical panel cutout dimension with H01/H02 for universal flush embedded installation on DCS control desk.

• Dustproof Design: Thickened surrounding rubber dust-proof gasket to block control room fine dust entering internal roller mechanical structure for long-term continuous 24h operation.

• Operating Ambient: Working temperature 0℃ ~ +55℃; storage temperature -40℃ ~ +85℃; relative humidity 5%~95% non-condensing, compliant with CE industrial component safety standard.

Core Differentiation vs H01 & H02

1. H01: White shell, fixed single SUNMD protocol only

2. H02: Black shell, fixed single SUNID protocol only

3. H06: Black shell, dual SUNMD/SUNID auto-switch protocol, universal interchange for all WEStation SPARC & UltraSPARC host boards

4. Main Functions

1. DCS console main cursor control device to select pump, valve, equipment icons on WDPF real-time monitoring graphic screens instead of regular computer mouse.

2. Cooperate with cabinet membrane keyboard to finish parameter setpoint adjustment, alarm confirmation, screen page switching, control logic parameter download and daily system operation.

3. Preferred replacement spare part for mixed-version WEStation upgrading & retrofit projects in coal-fired power, combined-cycle and nuclear power central control room.
