PakBus Networking Guide

• The PC's RF400 needs its own 12 VDC supply.

• This network behaves the same as the ‘minimum network’.

• You can install a Neighbor Filter in CR10XPB making it a ROUTER and

add CR205s to the network. By so doing you would end up with the Quick

Start network described in Section 2 of this guide.

3.1.4 Minimum + Phone Modem + RF400 Network

Adding a telephone modem link for the first hop:

• LoggerNet’s Setup device map now looks like this:

CR10XPB

• If the RF400’s Active Interface is configured for “COM2xx to RF400” a

PS100 and an A100 will be needed to power the two peripherals and

provide a CS I/O null modem. Or the RF400 Active Interface can be set for

CSDC (7) and a PakBus datalogger connected along with the COM210.

• Alternatively, for TCP/IP communications substitute an NL100 for the

COM210 and an IPPort in LoggerNet instead of the COM port.

• Multidrop communications could be used substituting a pair of MD485s

for the PC modem and COM210. An RS-485 twisted pair cable connects

MD485s. Additional MD485s with dataloggers can be added. Remember

to give each datalogger a unique PakBus Address.

3.1.5 Interface/ Com Port Considerations

A PakBus datalogger can interface to a communications peripheral using the

protocols listed below. The CR23XPB, CR200 Series, and NL100 have an RS-

232 port.

• Modem Enabled

Non-CRBasic PakBus dataloggers support M.E. (modem enabled)

communications (like non-PakBus dataloggers, only one M.E. device can

be connected to a datalogger).
