2.3.3.1 Wiring
Wire the Peripheral RS485 terminals A OUT and B OUT to a peripheral bus module RS485 (PBUS) terminals A and B
(A to A, B to B) [see figure 9]. Place a 150 Ohm filtering end-of-line (EOL) resister on the last peripheral bus module.
Note: Though the AX-PENN (/ST7) can support Class A PBUS (peripheral bus) wiring, this feature is presently
not available, as existing peripheral bus modules do not support Class A communications.
2.3.4 Optional AX-DSP Keyboard Display
The AX-PENN (/ST7) can support a standard Advanced AX-DSP keyboard display, simply wire the keyboard display
cable to the AX serial port on the AX-PENN (/ST7) [see figure 10].
