Shipment:
- Long range data transceiver for industrial use, the distance can up to more than 10km
- TTL, RS232 (or 485), customized
- Product model: SG-F408
- Generally, there are three important points must be emphasized
- Communication interfaces are the same standard RS485/RS232 interface
- Same baud rate at 2400bps
- Terminal access method and the commonly used method of cable access must be in the same parity bit
- Transfer rate: 2400bps, compatible voice or data signal transmission
- Can be set 256 Spots, the channel spacing is 25KHZ (standard)
- Integration of transceiver, both digital and analog signals can be send and switch quickly
- Either co-frequency or unco-frequency in air transmission
- Double loop and VCO structure, high stability
- Use 30W imported power amplifier module
- Use standard TTL, RS232 (or 485) level, convenient to connect to the control keyboard or personal computer directly
- SMT design, stainless steel outshell, miniature size and easy to install, can stick heat sinks
- Testing methods is in accordance with Mobile Communications “90” standard
- Please make sure that the current is switched off before you install the antennas
- And there is more than 10 meters between the two to avoid signals jam because of too strong signals
- Influence the second sale of products do not belong to the category of return within 30 days you get this product
- Such as appearance injury, high-voltage fuse, damp, broken seals, soaking, and more
- Transportation costs of replacement, repair and more
- Paid by the buyer
- One year free warranty, 3 months for spare parts
- We only charge for replacement parts cost when exceed one year
- Items are only shipped after all payments are received by DHL, UPS, FedEx and more, within 1-7 working days
