Wireless E84 Digital Communication Device (WDCD-3310)
User Manual
Introduction
WDCD-3310 is a device that enables E84 interlock communication via wireless communication during FOUP transfer between the OHT (Overhead Hoist Transfer) and semiconductor manufacturing equipment. The WDCD-3310 is equipped on the semiconductor manufacturing equipment.
Device Overview
Device Layout
The WDCD-3310 features a compact design with various connectors and status indicators. The top panel displays:
- LED Indicators: POWER LED, STATUS LED, and W-E84 LED, which provide visual feedback on the device's operational state (e.g., Power On, Program Changing, Hardware Error, Communication Status).
- Connectors: Antenna connector for wireless connectivity, a Micro USB port for debugging, a DIP Switch for configuration, a Push Switch for initialization, and a 10-pin connector for interfacing with semiconductor manufacturing equipment.
The bottom panel includes additional connectors essential for system integration:
- 5-pin Connector: Used for internal ROM writing (factory use).
- 3-pin Connector: Serves as a debug port.
- 12-pin Connector: Connects to semiconductor manufacturing equipment.

FCC Compliance Statement
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference undesired operation.
FCC CAUTION
Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
Note:
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.
Compliance with FCC requirement 15.407©
Data transmission is always initiated by software, which is passed down through the MAC, through the digital and analog baseband, and finally to the RF chip. Several special packets are initiated by the MAC. These are the only ways the digital baseband portion will turn on the RF transmitter, which it then turns off at the end of the transmission. The transmitter will be on only while one of the aforementioned packets is being transmitted. In other words, this device automatically discontinues transmission in case of either absence of information to transmit or operational failure.
Frequency Tolerance: ±60 ppm
This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines as this equipment has very low levels of RF energy.
