YWS direct connection to PMS
Figure 9-1 shows the YWS direct connection to the PMS. Note the following
requirements about this type of connection:
• The direct connection method can be used only when the YWS is less than
50 ft (15 m) from the PMS interface.
• The YWS is a PC, which in the RS232 connection standard is a Data
Terminal Equipment (DTE) device. If the PMS interface connection is also
a DTE device, a "null-modem" RS232 cable must be used for any direct
DTE-DTE connection.
• If the PMS interface is Data Circuit-terminating Equipment (DCE) device,
a straight RS232 cable must be used.
Procedure 9-1 on page 9-5 describes how to determine if the PMS is a DCE or
DTE device.
