PSM2001ACD and Server Gateway Interface Method
and Configuration
PSM2001ACD conforms to the MCUap
TM
Protocol to interface with the server
gateway. PSM2001ACD is able to interface with the gateway through any of the
following three modes. The following describes the configuration and connection
of these modes.
7.3.1
RS-232 Mode
As shown in Figure 9, the PSM2001ACD connects to the server gateway
through the RS-232 connection mode. It should be noted that the RSO1
pin of PSM2001ACD must be connected directly to the RSI pin. 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, the PSM2001ACD connects to the server gateway
through the RS-485 connection mode. It should be noted that the RSO2
pin of the PSM2001ACD must be connected to the RSI pin directly, and
other unused pins must be left open.
