(4)Point-to-Point Remote/Repeater

Option 4 allows you to designate the radio modem to act as either a remote or a repeater, depending upon the instructions received from the master for the specific communications session. When a radio modem is placed in an ideal location, this setting offers the flexibility of using that radio modem as an end point in the communications link (remote) or to extend the link to a point further (repeater). These functions are not, however, available simultaneously (the radio modem cannot act as both a remote and a repeater at the same time).

A word of caution: Configured as a repeater, a radio modem has no security features as explained below. When a radio modem is designated as a point-to-point remote/repeater, it will allow any master to use it as a repeater.

(5)Point-to-Point Repeater

Do not use this mode with the DDAA1000/DD1000

If a repeater is need in the system do not use a DDAA1000/DD1000. If and extended range of non-line-of-sight situation exists, use the Data-Linc Group SRM6000 radio modem as a repeater. When designated as a repeater, a radio modem behaves as a pass-through link. All settings for the call book, baud rates, and radio transmission characteristics are disabled. A repeater will connect with any master that calls it (the repeater must still be set up in the master’s call book).

The use of one repeater in a communications link will reduce the top data throughput available when compared to a direct master to remote link (generally on the order of 50%). This impact is generally noticed only when using the radio modems at 115.2 Kbaud. The throughput does not decrease further if two repeaters are used. The highest baud rate that can be used in a DDAA1000/DD1000 is 19200 bps.

(6) Point-to-Point Remote/Master Switchable

Do not use this mode with the DDAA1000/DD1000

(7)Point-to-Multi-Point Repeater

Do not use this mode with the DDAA1000/DD1000. See Mode 5 notes above.

(F)Ethernet Options

Do not use this mode with the DDAA1000/DD1000.
