Note: NOTES: 1. Shielded twisted pair cable should be used for connection. 2. The maximum distance of the whole interconnection is 50m, i.e. the connection distance count from the first antenna to the last antenna should be less than 50m. 3. Each set of antennae can have only one Master and the other Slaves. One Master antenna can link with a maximum of 30 Slave antennae. 4. Distance of each synchronization cable should not be more than 30cm from main cable.

J104 J101 Software Tuning In normal circumstances, there is no need for software adjustments as at factory setting, the electronics are set to the optimal level. However, should the environmental condition differ significantly or there are strong interference, changing the system settings via software may enhance system operation. a, Prior to using the software: J102 in PCB should be short circulated by placing plastic cap. Once adjustment is made, the plastic cap in J102 should be disconnected.

SAVE and LOAD LOAD: will transmit the latest setting to the PCB but it will not SAVE. It is used to check performance based on changes but when machine is turned off, the latest setting will not be saved. SAVE: after LOAD then press SAVE and the latest setting will be saved and operate when machine restarts. Under [Set‐up], there are seven settings:‐ 1, Transmission Setting Center frequency: 8.2 factory setting, others 8.6, 9.0, 9.5 Frequency range: 7.6~8.7 factory setting, range from 7.4~10 Mode: n.a.

Under [Data]:‐ The software can show signal strength of antenna from 16 different points. This will allow technicians to identify and reduce, eliminate area with interference. 1, 2, 3, 4, 5, 6, [Antenna configuration]: can only one configuration at a time [Type]: ?? [Range]: to adjust size of display V0 ~ V3 V0 : [Gate A] V1: [Gate B] Adjust whichever Gate has a higher reading. Objective: Adjust so that V3 is greater than V2 by 1.5 times.
