14-8 SLC Passthru Communications
Using RSLinx Classic, version 2.50 and higher, with SLC 5/04 
Passthru
RSLinx Classic, version 2.42 and below, only supports DF1 Full-duplex to 
DH+, DF1 Half-duplex Master to DH+, DH-485 to DH+, DH+ to DF1 
Full-duplex, and DH+ to DH-485 passthru. RSLinx Classic, version 2.43 
supports all modes of channel-to-channel passthru described below, except 
when channel 0 control line handshaking is enabled. RSLinx Classic, version 
2.50 and higher supports all modes of channel-to-channel passthru as 
described below.
When channel 0 is configured for DF1 Full-duplex and S:34/5=1, the SLC 
5/04 passthru processor can be used by RSLinx to go online through channel 
0 to the channel 1 DH+ network. The RSLinx RS-232 DF1 driver is used, 
with the device configured for 1770-KF2/1785-KE. The passthru processor 
will appear on the RSWho browse at its DH+ node address. You should 
configure the properties of the DH+ network within RSWho to only browse 
the specific range of addresses that are being utilized on the DH+ network.
When channel 0 is configured for DF1 Half-duplex Master and S:34/5=1, the 
SLC 5/04 passthru processor can be used by RSLinx to go online through 
channel 0 to the channel 1 DH+ network. The RSLinx DF1 Slave driver is 
used. The SLC 5/04 passthru processor channel 0 configuration must be set 
up in Standard Polling Mode, and the slave address of RSLinx must be 
included in the polling range. The DF1 Slave driver properties in RSWho must 
be modified to poll for the valid 5/04 DF1 Half-duplex Master passthru range 
of addresses, which is 128 to 191 (for DH+ nodes 0 to 77 octal or 0 to 63 
decimal). The passthru processor will appear on the RSWho browse at 128 
plus its decimal DH+ node address. You should configure the properties of 
the DH+ network within RSWho to only browse the specific range of 
addresses that are being utilized on the DH+ network.
When channel 0 is configured for DH-485 and S:34/0=0, the SLC 5/04 
passthru processor can be used by RSLinx to go online through channel 0 to 
the channel 1 DH+ network, when the PC running RSLinx is directly 
connected to the DH-485 network through a 1784-KTX(D), -PKTX(D), or –
PCMK card. When RSWho is browsing the SLC 5/04 on DH-485 with 
S:34/0=0, then a ‘+’ sign will appear to the left of the SLC 5/04 icon. Clicking 
on the ‘+’ sign will expose a DH+ network underneath the SLC 5/04 icon. 
Clicking on the ‘+’ sign to the left of the DH+ network will result in RSWho 
browsing for nodes 0 to 77 (octal) on the DH+ network. You should 
configure the properties of the DH+ network within RSWho to browse the 
specific range of addresses that are being utilized on the DH+ network.
When channel 0 is configured for either DF1 Full-duplex, DF1 Half-Duple 
Master, DF1 Radio Modem (with S:34/5=1), or DH-485 (with S:34/0=0), the 
SLC 5/04 passthru processor can be used by RSLinx to go online through 
channel 1 to the channel 0 DF1 or DH-485 network, as long as the PC 
running RSLinx is directly connected to the DH+ network through a
