Structure & Composition
- Core Processing Unit: LAN Control Processor (LCP), responsible for protocol stack parsing and command forwarding.
- Memory: Dual-port RAM (high-speed cache) + two EPROM cards (program storage).
- Connectors: Five dedicated connectors (2PL, 3PL, 10PL, ARCPL, KPPL) to realize the access of power, signals and keyboard.
- Bracket & Interface: It needs to be inserted into the SDCC bracket during installation, and connected to the programmer module through KPPL.

Installation & Maintenance Guidelines
Installation
- Confirm insertion into the bracket (support) on the SDCC board.
- Properly connect interfaces such as 2PL (power), 3PL (input) and 10PL (LAN I/O).
- Use KPPL to connect the programmer keyboard for parameter setting.
Maintenance
- Jumper Settings: The board may be equipped with hardware jumpers (Berg type or WJ/JP type) for setting isolated and non-isolated circuits, which must be configured in accordance with the manual (GEI-100162).
- Program Update: If the control program needs to be replaced, replace the EPROM card or use a programmer to download a new program through the KPPL interface.
- Environment Inspection: Regularly check the contact status of the connectors, ensure that the operating temperature (-40℃ to +70℃) does not exceed the range, so as to prevent communication failures caused by overheating or overcooling of the environment.
