• Manufacturer Part Number: dpc-64-rs232
• Description: Dpc-64-rs232 Transceiver Module
• Manufacturer: ABACOM Technologies, Inc

A four wire interface is used by implementing TxD, RxD, GND and CTS. The CTS flow control
line is available for users who wish to transmit more than 64 bytes. Under this condition, when the
DPC has received 64 bytes, the DPC will signal the host to pause sending data allowing it to
transmit the 64 bytes of data to the receiving DPC. Once the DPC has transmitted the data, the
CTS flow control line will toggle, allowing the DPC to receive the next 64 bytes of data from the
host.
The host terminal should be set to 9600 , 8, N, 1 and flow control should be set to ON
( substitute for other data rates)
The flow control line can be ignored if the total data to be transmitted is less than 64 bytes.
No flow control is used when uploading the received data from the DPC to the receiving host. The
relevant flow control lines have been looped back on the DPC.
Test Mode
The DPC features a test mode which is very useful to quickly test the integrity of the RF link.
When the test button is pressed, the DPC will transmit an internally generated test message to
the receiving DPC. The received test message will be displayed on the receiving host terminal
screen when running a terminal program, for example.
Note: For volume applications, the content of the preset message can be customized if required.
