3.4 RS-232 Interface and Host Settings

An RS-232 terminal or host computer connects to the RS-232 Host Interface on the Pan-Tilt

Unit. The host terminal or computer should be set to 9600 baud, 1 start bit, 8 data bits, 1 stop bit,

and no parity. Hardware handshaking and XON/XOFF are not used.

The RS-232 connections to the Pan-Tilt are: TxD (pin 2), RxD (pin 3), and GND (pin 5).

Figure 3 shows cable configurations for some common computer hosts. Since TxD and RxD

assignments to pins 2 and 3 can vary on host computers, try using a null modem if your initial

connection does not work.
