Setting up for Remote Control
Connecting the TIMS to a Controller
To connect the 4934A to a controller, use an appropriate serial cable from the unit's
serial port (on the right side) to the serial port on the controller.
For 4934A pinout information, see
4934A TIMS Serial Port Pinout,
page 7-2.
For cable information, see
Cable Pinout,
page 7-3.
Setting the Baud Rate
To change the 4934A serial port baud rate for remote control operation first put the
unit into LEVEL FREQ mode. Next press STORE followed by P/AR N.T. GND to
cycle through the baud rate choices. The display shows bd in the left display and the
current baud rate in the right display.
The baud rates available are 300, 1200, 2400,9600, and 19200.
NOTE
The 4934A always resets to 9600 baud at power up.
^_ The 4934A uses 8 data bits, no parity, 1 stop bit, and hardware flow control.
Activating Remote Mode
The 4934A enters remote control mode when it detects the RMT command at the
serial input. While the unit is in remote mode, the front-panel controls are locked out
(pressing any key displays a not local message).
Deactivating Remote Mode
The 4934A exits remote mode when it detects the LCL command at the serial port.
The unit returns to normal operation. You can also deactivate remote operation by
switching the unit off and then back on again.
