6 1 CONTROLS AND CONNECT ORS This chapter explains the function of each control and connector on the 9412/9412A. Front Panel The front panel contains the most frequently used controls and connectors. Display The 9412/9412A features a backlit liquid crystal display, which displays menu selections and settings.
7 Left Button (help) For numeric items, this button is used to select which digit in a numeric entry is selected for editing. For other items or when the left most digit is already selected for numeric i tems, pressing and holding this button down displays a brief description of the current item.

12 1 OPERATING INSTRUCTIO NS This chapter presents detailed instructions on the operation of the 9412/9412A. Overview The 9412/9412A uses a single - line L CD to display menu selections. The front panel keys are used to "navigate" through sets of menus to set various options and control the pulse ge n era- tor.
13 Main Menu The Main Menu consists of a set of menu selections used to set the operating mode, time p e- riod and frequency of the 9412/9412A. MODE - Pulse Modes There are five (5) different Pulse modes available.
14 Duty Cycle The Duty Cycle mode is similar to Continuous mode in that a continuous stream of pulses is output. The exception is the outputs are only active for a set number of seconds ( DC:On menu), then disabled for another set time period ( DC:Off menu) before being re - enabled.
15 ToPer - To Period Except when in External Trigger or Single Shot mode, all pulse outputs are based on an i n te r- nal timer called To. This menu is used to select the rate at which To runs by selecting the time period in microseconds between timer pulses.
16 When set to Positive , the output will initially be at 0 Volts. When active, will go high for the specified pulse width time, after which it will return to 0. The voltage level while high w ill d e- pend upon the load and the setting of the output voltage adjustment on the back panel.
17 T2:Wait The output of Channel 2 can be delayed for a number of pulses. This menu is used to set the number of pulses that must occur on the other channels before the output o f Channel 2 is e n- abled.
18 RECALL Configuration Recalls a previously stored configuration from the specified memory location. To rec all a configuration use the Up and Down arrow keys to select the memory location number and press the Left or Right arrow key. You will be prompted to press the key to verify that you want to overwrite the active configuration.

21 1 COMPUTER INTERFACE The 9412/9412A comes standard with an RS232 serial interface. All menu settings can be set and retrieved over the computer interface using a simple command language.
22 P P CR is a carriage return character (ASCII value 13). With echo enabled, all characters sent will be echoed back to the sender. Unidentified commands and most out of range conditions result in the pulse generator igno r ing the command.
23 Communication Protocol Communication parameters are set at 9600 baud, 8 bits, parity = none, and 1 stop bit. To help establish RS232 communications, the pulse generator emits the characters QC a p proximately every 200 ms after power up and until the 9412/9412A receives a $ .
24 Command List The following table summarizes all the commands. Note: The name of each command is identical to how it appears on the dis play of the 9412/9412A.
25 9412/9412A Communication Commands Command Name Parameters Description MODE 0 = Continuous mode 1 = Burst mode 2 = Duty Cycle mode 3 = Single Shot mode 4 = External Trigger mode Sets the pulse generator mode. GATE 0 = off 1 = active low 2 = active high Enables the external trigger input to function as a gate controlling all outputs.
26 9412/9412A Communication Commands RECALL 0 - 4 (9412) 0 - 8 (9412A) Recall a stored configuration. STORE 1 - 4 (9412) 1 - 8 (9412A) Store a configuration. SHOTS (9412A Only) 0 = Reset to zero Resets shot counter. SHOT ? will return the number of shots.
