7.3 77709 HAND CONTROLLER
The Hand Controller is a very compact hand held device with backlit LCD, and 40-key keypad.
Virtually every function of the MS257 can be controlled from the keypad, from simply moving to a
particular wavelength, to changing the grating and filter selections. It comes with a 14 ft (4.5 m)
cable.
MS257 Hand Controller Operation
The Hand Controller controls MS257 via an RJ11 jack on the back panel. System parameters
may be edited from the controller's front panel. The grating's position can be changed from the
hand controller and devices can be selected (filters, slits, slow shutter, output flip mirror and
grating changer).
The Hand Controller has three functional areas:
5 System Status LEDs
4 x 20 LCD screen for system information and parameter editing
5 x 8 Keypad (10 numeric,
5
editing keys, 24 command keys, 1 shift key)
The MS257 starts up in the Remote mode of operation (controlled via the USB or RS232 port). To
initiate control by the hand controller, the
Local
command key must be pressed. The shifted
command,
Rem,
returns control of MS257 to the computer.
Transferring of control of the MS257 between the Hand Controller and the computer can only be
initiated with the Hand Controller.
