3. Temporarily remove the 6‑32 1/4″ screw and lock washer secured to the hex stand‑off located to the
right of the socket.
4. Install the modem PCB by mating its sixteen‑pin female connector with the Processor PCB socket. Use
the 6‑32 screw and lock washer to secure the modem to the hex stand‑off.
5. Reassemble the logger.
When the VDL is reinitialized the firmware will automatically detect the modem’s presence and configure
it for auto‑answer and originate operation.

The VDL can be equipped with a 10 / 100 Base‑T Ethernet Port. The optional Ethernet Port allows high
speed local or remote access to the logger via a TCP / IP‑based Local Area Network (LAN) connection. It
uses the internal power of the VDL rather than commercial AC power. Table 14 on page 87 lists the bit
transfer rates of each user accessible port.
Generally, the Ethernet Port is ordered at the time the logger is purchased and is pre‑installed at the
factory. If the port was not previously ordered the user may wish to install it after delivery of the logger. To
install the Ethernet Port follow the steps listed below.
1. Completely remove the logger’s front panel assembly in accordance with the procedure entitled
“Working Inside the Data Logger” on page 73 .
2. Remove and discard the protective plate that covers the Ethernet Port opening located at the top
panel. A 6‑32 1/4″ nut secures the protective plate.
