3.3 Communication Ports
The S600 CPU has nine standard communication ports (eight serial
and one Ethernet). Table 3-4 details the communications ports.
Note: Comm Ports 1 and 8 contain internal connections to other boards
in the S600 which are not available for external host or local operator
communications. You can use Comm Port 1 to route Remote Display
connections. Comm Port 2 is normally reserved for Config600/IPL
600.

Communications Port Backplate Descriptor Description
Comm 1 COM1-2 Internal (Connection to Front Panel Keypad)
Comm 2 COM1-2 Config600/IPL 600
Comm 3 COM3 EIA-232 (RS-232)
Comm 4 COM4 EIA-232 (RS-232)
Comm 5, 6 & 7 TB2 EIA-422 (RS-422) or EIA-485 (RS-485)
Comm 8 Remote I/O
External (Reserved for future use) and Internal
(Connection to I/O Boards)
Comm 9 Network Ethernet
For information on the communications port on the front panel which
can also act as Comm 2, refer to Chapter 5, Front Panel. For
information on the optional second Ethernet port, refer to Section 3.6,
Dual Ethernet LAN Port.
3.3.1 EIA-232 (RS-232) Serial Port
Two EIA-232 (RS-232D) communications ports are provided on the
P152 CPU board’s backplate. The ports use FCC-68 RJ-45 connectors
and are labeled COM3 and COM4. The COM3 and COM4 pin
connections are shown in Table 3-5. Figure 3-4 shows a sample pin
connection.
Converters are commercially available to configure either 9-way D
type or 25-way D type connection. The ports support baud rates from
300 to 38400 bps.
