If you are interfacing a DTE device to the Model 24SII DES (DCE),

you must use a one-to-one or straight cable as shown in

Figure 5

the following page. If you are interfacing a DCE device to the Model

24SII DES (DCE), you must use a crossed cable as shown in

Figure 6

on the following page.

When using XON/XOFF protocol, it may be desirable to use cables

with only Tx, Rx and GND connected. On the serial ports of a

BayTech Model 24SII DES, input handshaking lines are enabled if

nothing is connected, allowing the system to operate with only Tx, Rx

and GND connected.

CAUTION: Do not attempt to use a serial cable on a parallel port.

Since an EIA-232 serial port usually carries a potential of +12 and -12

volts, plugging a serial cable from that port into a parallel port may

cause damage to the parallel port.
