(1) Direct Burial Splice Kit
(1) 20 foot Telephone Patch Cord with Connector
1. Connect the 20 foot patch cord to connector marked COM
on the external back panel, under the protective cover.
2. Splice the labeled "Tip" and "Ring" lines of the patch cord to
the telephone service line. Use the direct burial splice kit
when splices are in a valve box or buried.
NOTE - The splice and wire nut must be completely immersed into
the silicon gel inside the splice tube to be waterproof.
4.2.2 Short Haul Modems
Short-haul modems enable communication between a datalogger and
computer over two twisted pairs of wires. The maximum distance
between modems is determined by baud rate and wire gauge. At 9600
baud, the approximate maximum cable length is 6.0 miles using 19 AWG
cable. DCE / DTE switches on the modems are set to DCE.
NOTE - It's critical to use at least a two twisted-pair cable with a shield
wire. Shield wire(s) and/or any additional unused conductors must
connect to an earth ground at one end or the other of the cable run.
