FloBoss S600 Instruction Manual
3.3.2 EIA-422 (RS-422)/EIA-485 (RS-485) Multi-drop Port
Three EIA-422 (RS-422) or EIA-485 (RS-485) ports are located on the backplate of the P152 CPU board
and provide high speed/long distance links of up to 38400 bps and 1200 m (4000 ft). The ports use the
connector labeled TB-2, which is COM5, COM6, and COM7. The COM5, COM6, and COM7 pin
connections are shown in Table 3-6.
NOTE: For two-wire EIA-485 (RS-485) installations, jumper TX+ to RX+ and TX- to RX- on the
TB-2 connector on the P152 CPU board .
3.3.3 Ethernet LAN Port
The standard Ethernet port on the backplate of the CPU card is for high-speed communications using an
Ethernet Local Area Network (LAN) architecture. The speed of data transfer is 10M bps when using
10BaseT twisted pair cable.
The port uses a FCC-68 RJ-45 connector. The port is labeled Network on the backplate of the P152 CPU.
It is the standard Ethernet port. No hardware configuration or wiring is required for this communications
port.
NOTE: For information on the optional, second Ethernet port, refer to Section 3.6.
3.3.4 Local Operator PC or Remote Display Port
The connector labeled COM1-2 on the backplate of the P152 CPU board is used to connect the FloBoss
S600 to a remote display (COM1) or the host PC (COM2). The COM1-2 port should not be modified by
the user for other functions.
The COM1-2 port uses a standard 15-way D-type female connector. The COM1-2 pin connections are
shown in Table 3-7.
