BCD to 16 converter

BCD to 16 converter

Simply but powerful converter/decoder from BCD data input to 16 outputs, compatible with Yaesu BCD. You can use it everywhere you have less wires than you need and also with BCD (TTL) output devices (like Microham).

Using

Universal converter/decoder BCD to 16
Compatible with YAESU BCD output
Antenna band decoder
When you miss wires to your tower :)
Remote control expander

Main functions

BCD to 16 matrix table
YAESU BCD to 16 outputs
YAESU BDC BAND DECODER
Outputs 0 to 15
LED indications
Universal OUTPUT: + or GND
BCD input HIGH with 2.6 to 15V - UNIVERSAL: TTL and up to 15V
PTT hot switch protection
RF and high voltage protections
TBD and ULN drivers (2 pairs) are included
RF and high voltage protections
ASSEMBLED and TESTED VERSION

Parameters

Matrix table for inputs and outputs

Connection of control cables and power supply

- power supply input
- BCD input voltage 2.6 to 15 V DC

PTT hot switch protection

- you can use this PTT input as Hot Switch protection
- active when LOW

Output voltage

- output voltage for TBD driver
- +12 means supply voltage of BCD board
- EXT is external voltage - for relays with different voltage than 12 V (could be 5 or 24 V DC)

Output driver

- universal outputs - switching to GND or + voltage
- easy to set by jumper
- easy to replace driver ULN (- out) / TBD (+ out)

Example with 6-to-1

- need four (five) wires between controller and BCD to 16 converter
- GND, (+12V) and three control wires
- output must be with TBD drivers (+ out)

Example with PA BCD output

- compatible with OM-power amplifier Manual page 51 (ANT/BPF DB15)
- need four (three) wires between controller and BCD to 16 converter
- GND, (+12V) and three control wires
- output must be with TBD driver (+ out)

Example with 6-to-2 and microHAM devices

- need four (three) wires between controller and BCD to 16 converter
- GND, (+12V) and three control wires
- output must be with TBD driver (+ out)

HV8DC board

This is a specially designed board to protect up to 8 DC control wires. The connection between the control box and the equipment outside (on the mast) can be dangerous - due to storms a potential difference can easily occur or voltage can be induced on the control wires. This phenomenon is dangerous and it is necessary to safely discharge this voltage to a common earth potential.
