support pole. Please refer to the following instructions for mounting the enclosure onto a 2” pole
and pole mounting (as shown in Figure 1).
•Please align the holes of the single tab mounting bracket with the groove on the enclosure
when the enclosure is vertical.
•Facing the enclosure's front, use item 3 (Figure 1) to hold the enclosure against the bracket.
Place flat and lock washers over the threads on item 3 (Figure 1) when facing the
enclosure's rear and join with nuts.
•Install the two pipe clamps on the pole using the provided hardware.
•Loosen set screw as shown in figure 1 to adjust meter orientation, maximum 180° rotation
from starting point.

4Electrical Connection
This section covers all electrical connection requirement. Electrical connection of the device must
be carried out by trained; qualified specialists authorized to perform such work by the installation
site.
WARNING
•Connect all electrical cables when the power is switched off. If the device does not

4.9 Communication
4.9.1 Local Serial Communication Port
The terminal board provides one RS232 compatible local communication port (CHIT) for
calibration and configuration of the unit using a laptop and configuration software.
Table 10: Cable assemblies for CHIT connector
Assembly P/N
Description
3-0446-090
DB9S connecter with 15-ft cable for use with the six-position connecter
3-0446-090B
DB9S connecter with 25-ft cable for use with the six-position connecter
4.9.2 Bluetooth LE
Bluetooth Low Energy connection is available. A Bluetooth Low Energy Dongle is required to
operate this function (Contact Tek-Trol for this device).
4.9.3 RS232 Mode
•If not used internally, the communication port can interface to any RS232 compatible
customer device, such as a radio.
•Do not exceed +15VDC on any of the communication lines.
•Host communication port RS232 connections are identified in the following Table 11.

*Note:
For RS232 mode, do not install jumper J14.
For RS232 mode without DCD signal, install jumper J16.
4.9.4 RS485 Mode
•The host communication port supports RS485 communication.
•To use RS485 mode, jumpers J14 and J16 must be installed.
•Select RS485 2-wire mode by installing a jumper on J12 pins 2-3.
•Remove the jumper for 4-wire mode.
4.9.5 Ethernet Port
Jumper J4 on the main board is a 10M/100M Ethernet port supports standard TCP/IP protocol.
