D. BAUD RATE FOR RS-232 COMMUNICATION
The Infinity can receive and transmit data via an RS-232 serial port at one of four baud rates (300,
1200, 2400, and 4800). The factory setting is 4800 baud.
Change the baud rate by moving the jumper on the RS-232 BAUD SEL shorting block (Fig. 3/4).
NOTE:
•
Make sure the baud rate is the same on all Multi-Link units in the chain.
••••
Make sure the baud rate is the same for any external device you connect, such as a
printer or terminal
