WL-19D RF Modem Installation and Operating Instructions
Read Instructions Completely Before Installing Equipment
Installation and Wiring
1. The WL-19D should be mounted high above ground and in a place that gives clear line of sight to the
other wireless unit it will be communicating with. The directional yagi antenna is manufactured by
CUSHCRAFT and comes with its own set of instructions . Carefully read all instructions before installing the
antenna. The cable from the antenna directly connects to the cable from the WL-19D. These N-type
connectors are weather proof, however, added sealant over the mated connectors is recommended.
IMPORTANT: The antennas at each end of the wireless link should be mounted such that their element(s)
have the same orientation. Normal practice is to mount all antennas with their elements vertical as shown
Figure 1.
LIGHTNING: A low resistance earth ground on the antenna and mast is critical for lightning protection. Some
additional degree of lightning protection may be provided by not mounting the yagi antenna as the highest
point on a structure. An optional lightning arrester kit is available from BinMaster and should be used in
areas where lightning is of concern. The antenna with lightning arrester is shown in Figure 2.
2. The WL-19D will operate from 115 VAC, 230 VAC or 12 to 24 VDC. A voltage selector on the WL-19D
circuit board must be set to match the AC input voltage. A separate set of polarized input terminals are
provided for DC operation. The DC power may be either ungrounded or have a negative ground. Refer to
the wiring diagram shown in Figure 3. All wiring to the unit should be in accordance with the National
Electrical Code and any applicable local codes. In all cases, a good electrical earth ground should be
connected to the G terminal of the WL-19.
3. A quality shielded twisted pair communication cable such as Belden 9463 should be used for the RS485
network. Connect the RS485 communication cable to the appropriate WL-19D terminals. NOTE: The RS485
network is a polarized (+/-) system. Take care to maintain consistent wire polarity throughout the entire
network when connecting to all other devices .
4. TERM: The jumper on the WL-19D circuit board labeled TERM is typically set to the ON position. This is
because the WL-19D is usually at one end of the RS485 network cable. If, however, the WL-19D is in the
middle of a long network then the TERM jumper would be set to OFF and the devices at each end of the
network would have their terminations set to ON.
5. BIAS: Both BIAS jumpers on the WL-19D circuit board are typically set to ON. However, if a computer
interface device or other BinMaster controller is also connected to the same wired RS485 network, then that
device may be biasing the network in which case the WL-19D BIAS jumpers would be set to OFF.
Operation
1. The WL-19D does not require any operator adjustments or actions for operation.
2. The red POWER indicator light located near the RS485 connector on the WL-19D circuit board should be
ON whenever power is applied to the unit.
3. There are four other LED indicator lights on the WL-19D circuit board which indicate the following:
DI
DO

Data In, flashes whenever data on the RS485 network is coming into
the WL-19D.
Data Out, flashes whenever data is moving out of the WL-19D onto
the RS-485 network.
