Extron electronic MTP U R RS SEQ manual Receiver Jumpers, Setting JMP1 for RS-232 communication

NThe transmitter and receiver are designed for and perform best with Extron Enhanced Skew-Free A/V cable terminated in accordance with the TIA/EIA T 568 A wiring standard. CAT 5 cables are acceptable but less preferable. We also recommend the use of pre-terminated and tested cables. Cables terminated on site should

be tested before use to ensure that they comply with Category 5/5e/6 specifications.

The recommendations shown in the table apply for a single transmitter and receiver. For example, the maximum suggested range for 1024 x 768 video is 300’ (90 m) with Pre-Peak off and 600’ (150 m) with it on.

Receiver Jumpers

The MTP U R receivers have three jumpers on the main board. Jumper 1 (JMP1) controls RS-232 directional communication, and Jumpers 2 (JMP2) and 3 (JMP3) control vertical and horizontal sync respectively.

By default, JMP1 is closed on all models and

configured to send serial data both ways (bidirectional), transmitter-to-receiver and receiver-to-transmitter. Jumpers 2 and 3 are open (negative sync) by default.

Setting JMP1 for RS-232 communication

Jumper 1 can be repositioned to enable unidirectional communication as follows:

1.	If applicable, disconnect all cables, remove the receiver
	from its installation location, and remove any mounting
	brackets installed.
2.	Remove the two screws from either side of the receiver
	(four screws total) and lift the top cover off of the receiver.
3.	Locate jumper JMP1 on the main board. Remove and
	reposition it over one pin (see figure 3).

Reposition the jumper block to cover one pin.

4.	Put the top cover back into place.
5.	Reinstall the four screws removed in step 2. If any
	mounting brackets were removed in step 1, put them back
	into position as you reinstall the screws
