I have a project that the pinout for various components is starting to make me doubt myself. I am hoping someone on here can confirm or correct my pinouts. The various tech support people are giving conflict information
First Connection A: TSXETG100 (DTE) RJ45 RS233 to 25pin DDS/MR64 Modem (DCE)
ETG100 MR64
1(DSR)----6(DSR)
2(RLSD)---8(RLSD)
3(DTR)----6(DSR)
4(SigGND)-7(SigGND)
5(Rx)-----3(Rx)
6(Tx)-----2(Tx)
7(CTS)----5(CTS)
8(RTS)----4(RTS)
I've been thinking about forgetting about the TSXETG100 and going straight from the Quantum PLC modbus port (DTE) directly to the DDS/MR64 Modem (DCE) 25pin serial port with the following pinout
9pin to 25pin
2 ------- 3
3 ------- 2
5 ------- 7
4 -| |- 4
6 -| |- 5
7 -|
8 -|
On the 9pin end 4 jumps to 6 & 7 jumps to 8
On the 25pin end 4 jumps to 5
Second Connection A: BM85 Mux (DTE?) to DDSMR64
When metered out an existing cable found the following connection:
Male 25pin Male 9pin
2---------------3
3---------------2
6---------------6
7---------------1
20--------------4
|-7
|-8
Again this seems to contradict the DTE to DCE rule of straight through. Is the BM85 a DTE or DCE?
If I were doing it I would do, Second Connection B:
9pin to 25pin
2 ------- 3
3 ------- 2
5 ------- 7
4 -| |- 4
6 -| |- 5
7 -|
8 -|
On the 9pin end 4 jumps to 6 & 7 jumps to 8
On the 25pin end 4 jumps to 5
Any help in this would be much appreciated. The pinout for the DDS/MR64 can be found:

If you are interested in the application see below:
I maintain and upgrade a SCADA (Wonderware) for monitoring in and controlling multiple liftstations and pumphouses from a central locations. All the remote facilities have modicon 984 PLCs and DDS/MR64 modems over Modbus RTU. The main pumphouse where the operator sits has a modem for each facility that are connected to BM85 muxes (MB to MB+) which is connected to the SCADA host PC running InTouch 9.5 and a SA85 MB+I/O Server.
A new facitity was recently built and employs a Quantum PLC with an NOE card. The NOE is connected to a switch. The TSXETG100 is also connected to the switch. I am confident the new topic definition an access name are configured correctly on the SCADA. I am sure the BM85 is configured correctly. The TSXETG100 I am 95% sure it is configured properly. The I/O server is still not seeing the new Quantum PLC leading me to believe there is cabling issue somewhere.
