Description

This is a universal Band Data BCD splitter board. This powerful board splits one 4-bit BCD input into two outputs. Thanks to the optocouplers, the split is separate and protects the source (TRX) from the peripherals (PA, BPF filter switch, band decoder, BCD-to-16 etc). The input is designed for a wide input voltage range. The board also includes Hot Switch protection - when a PTT signal is connected, the output state is latched and even if the input BCD data is changed, the output remains set until the PTT is interrupted (from TX to RX).

All three ports contain Pull-Up resistors. These can be connected using the Jumper. These resistors are important if the source of the BCD data is a device with an "Open Collector" - see more in the Manual. Likewise, the outputs can be Open Collector only, but can also output HIGH values with a 12V level across the resistor.

The board contains LED indication for input and output 4-bits of BCD data and PTT LED. The output "open collector" outputs are with power FET transistors and can switch higher current compared to BCD outputs on TRX, PA, Microham, etc.

Manual

If you want to know more please check our wiki with BCD splitter manual.

ATTENTION! The input and output Pull-Up resistors are connected from the board supply voltage. Therefore, if the board is powered at 13.8V, this voltage is applied across the resistors (2k2) to the appropriate pin. If the BCD output were connected to a device with 5V TTL logic, the connected device could be damaged!
