Triport Cable
The Triport cable is used for tapping serial RS-232 ports
available on most POS cash registers. The Tri-Port does not
interfere with any signals between the POS and the printer (if
there is an external printer connected).
For installation, do the following:
1. Remove the DB9 printer connector at the POS (if an
external printer is connected).
2. Install the Triport connector (printed circuit board) into
the vacated POS connector.
3. Connect the DB9 printer connector to the Triport.
4. Connect the Triport cable (gray cable w/DB-9S) to the
PB3.
NOTE1: If a printer was not attached to the POS, it may be necessary to
enable the serial port on the POS. Program the POS for a printer setting.
NOTE2: If the POS uses a DB-25 serial connector, use two “DB-25 to DB-9”
adaptors. These adaptors are readily available most electronic stores.
Hardware Handshake Jumpers JP1 and JP2
For a POS system with an external printer connected, remove
the JP1 and JP2 jumpers.
For a POS system without a printer, it may be necessary to
jumper one or both JP1/JP2.
• JP1 shorts pins 7 and 8 (RTS/CTS)
• JP2 shorts pins 4 and 6 (DTR/DSR)
