To connect a PC to a set of VS-812 units, do not use a Null-modem adapter.
Do the following:
1. Prepare the RS-232 9-pin D-sub connector (A), by connecting PIN 4 to
PIN 6 and connecting PINS 8, 7, and 1 together.
2. Attach the RS-232 9-pin D-sub connector (A) to another RS-232 9-pin
D-sub M connector (B) by connecting PIN 5 to PIN 5, PIN 3 to PIN 2,
and PIN 2 to PIN 3.
3. Connect the RS-232 9-pin D-sub connector (A) to your PC’s RS-232
9-pin D-sub M port.
4. Attach the RS-232 9-pin D-sub M connector (B) to another RS-232 9-pin
D-sub M connector (C), by connecting PIN 5 to PIN 5, PIN 8 to PIN 3,
PIN 9 to PIN 2.
5. Connect the RS-232 9-pin D-sub M connector (B) to the RS-232 9-pin
D-sub port on the first VS-812 unit.
6. Attach the RS-232 9-pin D-sub M connector (C) to another RS-232 9-pin
D-sub M connector, if required, by connecting PIN 5 to PIN 5, PIN 8 to
PIN 3, PIN 9 to PIN 2.
7. Connect the RS-232 9-pin D-sub M connector (C) to the RS-232 9-pin
D-sub port on the next VS-812 unit.
