PSM2000ACD and Server Gateway Interface Method
and Configuration
PSM2000ACD conforms to the MCUap
TM
Protocol to interface with the server
gateway. PSM2000ACD is able to interface with the gateway through any of the
following four modes. The following describes the configuration and connection of
these modes.
7.3.1
RS-232 Mode
As shown in Figure 9, the PSM2000ACD connects to the server gateway
through the RS-232 connection mode. It should be noted that the RSO1
pin of the PSM2000ACD must be connected to the RSI pin directly. RXD
and TXD are the receiving pin and transmitting pin respectively. Other
unused pins must be left open.

7.3.2
RS-485 Mode
As shown in Figure 10, PSM2000ACD connects to the server gateway
through the RS-485 mode. It should be noted that the RSO2 pin of the
PSM2000ACD must be connected to the RSI pin directly, and other unused
pins must be left open.
