Supplied with the 5200 are a YSI# 655384 Straight-pinned Cat 5 EIA568 compliant network patch cable
and pre-wired YSI# 655383 RJ-45 to DB-9 Adapter. The supplied cable and adapter are only intended to
be used for software upgrades or downloading data. Do not use this cable for long-term installation as the
compression fitting cannot form a proper seal. See Section 3.3.1 Sealants, Desiccants and Securing the
Monitor.
Bulk cable for permanent installations must be round (to allow the compression fitting to seal) and should
be purchased locally. A crimping tool will be required to install RJ-45 connectors to each end of the
cable.
IMPORTANT: 1. The connector that is to connect inside the case should be crimped after the cable is
run through the compression fitting.
2. Round cable must be used so a watertight seal at the compression can be achieved.
TCP/IP LAN Connection
An Ethernet serial server is required to connect the 5200 to a LAN. The serial server must be assigned a
static IP address.

Additional RS232 TCP/IP Wiring Information
The 5200 uses a symmetrical EIA-232 data terminal equipment (DTE) pinout on the RJ-45 serial port.
Table 3-1 lists the pinouts of the RJ-45 ports used for EIA-232 serial communications.
