PIN OUTS & SPECIFICATIONS
Pin In/Out Name Description
1 IN Analog Channel 1 Analog input for joystick control of axis. Voltage range is 0-2.5VDC, 8-bit A/D converter.
CAUTION: Input voltage must not exceed 5VDC.
2 IN Analog Channel 2 (same description as pin 1 above).
3 IN Analog Channel 3 (same description as pin 1 above).
8 — Shield Shield (chassis ground).
14 — Ground Digital ground.
15 IN Axes Select If using one joystick, you can use this input to alternately control axes 1 & 2. *
16 IN Velocity Select
Input to select high or low velocity range (as defined with the JOYVH or JOYVL commands). *
17 IN Joystick Release When low (grounded), joystick mode can be enabled. When high (not grounded), program
execution will continue with the first command after the joystick enable (JOY1) statement. *
18 IN Joystick Trigger
Status of this active-low input can be displayed with the TINOF command, or read by a program (using
the INO command) to control program flow or to enter the OEM6250 into joystick mode (JOY1). *
19 IN Joystick Auxiliary
Status of this active-low input can be displayed with the TINOF command, or read by a program
(using the INO command) to control program flow. *
23 OUT +5VDC (out) +5VDC power output.
* Input voltage range for pins 15-19 is 0-24VDC. HCMOS compatible (switching voltage levels: Low £ 1.00V, High ³ 3.25V).
