IGWiPS200-1
HAZARD LABEL A label, similar to that shown here, is included in a WiPS shipment. The installer or
user should post this label in an appropriate, highly visible location near the WiPS
modules. Possible label mounting locations include: on the outside of an enclosure
housing WiPS modules or inside that enclosure adjacent to the modules.
When WiPS transceivers are ordered, two or more transceivers are supplied as
matched devices, meaning that they share the same electronic identifier and
frequency hopping pattern. This data is stored in a Hop Key. The Hop Key in a
transceiver can be removed and physically transferred to another transceiver
producing a second matched transceiver. The original matched transceiver will
retain its Hop Key data and operate normally even though the Key has been
removed.
The following procedure describes transferring the Hop Key from a matched transceiver to an unmatched
transceiver (e.g. spare transceiver part number TGX:16347-320) thereby producing another matched transceiver.
The newly matched transceiver can then be used as a remote transceiver in a multipoint-to-point system, a spare
transceiver, or a replacement (master or remote) transceiver. Once the Hop Key is installed in the transceiver and
power is applied, the transceiver will memorize the identification, hop frequencies, and hop sequence of the matched
transceiver. When power is removed, it will retain this information, even if the Hop Key is removed. The newly
matched transceiver and the original matched transceiver will communicate with the other matched transceiver(s).
IMPORTANT
When replacing or adding a transceiver to a wireless network, remember that a network
node can have one (1) master transceiver and up to eight (8) remote transceivers.
To Transfer a Hop Key
1. Place an anti-static wrist strap on your wrist and connect the strap’s ground lead to a good ground.
2. If the transceiver is installed, remove power from the transceiver and all I/O connections.
Remove the wired connector blocks from the transceiver; see Figure 5 on page 17 for photographs
(alternatively, label each wire to facilitate reconnection and then disconnect the wires). Physically separate any
connected I/O modules and remove the transceiver from the DIN rail.
3. Remove the faceplate/circuit board assembly locating a rectangular recess near the numbered terminals on the
top of the transceiver cover (see Figure 4 on page 17 and Figure 20 below). With a small flat blade screwdriver,
press the tab in the recess inward and pull that corner of the faceplate outward slightly. Repeat this process at
the bottom of the transceiver. Carefully pull the faceplate/circuit board assembly from the cover.
