Buffered Radio Frequency Modem Interface

Automatic Handshake Control for RF Modems with RS-422/485 Conversion

Many low cost or older radio data links require that RTS be raised from the serial device to enable the radio's transmitter. This can be a problem for RS-232 devices with no handshake control or RS-422/485 systems where no handshake lines are typically present. The Model BAMHC solves this problem by providing hardware handshake control for radio frequency and other modems requiring the RTS line to control the transmitter. The BAMHC allows the use of legacy or low cost systems without the expense of updating to modems with buffering or built-in RS-485 interfaces.
