FIGURE 4a -- WIRED RS 485 FROM COMPUTER TO TS1 UNITS
FIGURE 4b -- WIRELESS FROM COMPUTER TO ONE TS1 WITH A RADIO MODULE,
WIRED RS 485 TO OTHER TS1’s WITHOUT RADIO MODULES
NOTE:
There can be only
one
TS1 unit having a wireless modem connected to each wired RS-485 net-
work. Do not connect multiple TS1 units with wireless modems to the same RS-485 network.
FIGURE 4c -- WIRELESS FROM COMPUTER TO ALL TS1’s WITH RADIO MODULES
2.5 WIRELESS MODEM
The optional wireless modem allows units to communicate without having interconnect-
ing wires. A system may consist of all TS1 units having wireless modems or just one
TS1 unit with a wireless modem and other TS1 units without wireless modems hard
wired to it with RS-485 cable. In such a case where one TS1 with a wireless modem
drives a hardwired RS-485 network, the TS1 with the wireless modem must have both of
its BIAS jumpers placed in the ON position and its TERM switch in the ON position. All
other units on the network should have their BIAS jumpers in the OFF position. The last
unit on the RS-485 network should have its TERM switch ON and all other units, except
the one with the wireless modem, should have their TERM switch OFF.
